What is Sodium Formate?
In chemistry, Sodium belongs to the alkali metal family with the atomic number 11 and the symbol Na. In the crust of the Earth, it is the sixth most prevalent element and is found in various minerals, including feldspars and rock salt (NaCl). Since sodium particles have been removed from Earth’s minerals over time by water’s activity, many sodium salts are incredibly water-solvent. As a result, sodium and chlorine are the most well-known disintegrating components by weight in the water.
Sodium formate is a white, powdery material that prefers to pick up moisture from the air and turn it into a liquid. Sodium Formate is also known as Formic acid and Sodium Hydrocarbon Dioxide and is designated as Sodium Methanoate by the IUPAC. Sodium formate has the chemical formula HCOONa. Its chemical composition qualifies it as the sodium salt of formic acid. It is, however, made in smaller quantities from formic acid rather than the other way around. Yet, sodium formate can be made in several ways, including neutralizing formic acid with sodium hydroxide. It’s also worth mentioning that sodium formate holds many physical and chemical properties. The crucial Chemical Properties are as follows:
- It is a salt of a weak acid (H2O) and a strong base (NaOH);
- It is slightly toxic to water and inhibits some bacteria while being degraded by others;
- When sodium formate is heated, sodium oxalate and hydrogen are produced. The created sodium oxalate can be further heated to break down into sodium carbonate, which releases carbon monoxide gas.
It also possesses the following Physical properties:
- Formic acid-like aromas can be detected in sodium formate;
- The refractive index of 1.371;
- A molecular weight of 68 g/mol;
- The density that is equal to 1.92g/cm3;
- The melting point of 253° C.
Due to its chemical and physical properties, sodium formate functions in a wide range of industries. It serves in various dyeing and printing procedures on fabrics. Additionally, it serves as a de-icing agent, a buffer for powerful mineral acids to boost their pH, and a food ingredient. It also acts as “drilling salts” and in “drilling mud.” In the oil industry, drilling salt is used as a supplement in the sub-drilling process. Because of their comparatively high density, saturated sodium formate solutions are utilized as drilling and stabilizing aids for exploring natural gas and oil. Any density between 1,0 and 2,3 g/cm3 can be set by combining the corresponding saturated alkali metal formate solutions.
Different Grades of Sodium Formate
Chemical grades are vital because they indicate whether a material complies with specified requirements. However, this concept is more complex than just using grades to indicate purity levels. While true, some chemical qualities will also be designed for a particular process, use, or market. For instance, chemical grades for food and pharmaceutical compounds may involve searching for toxins, metals, and bioactive impurities.
Monographs for chemicals serve as a standard, offering information about chemical compounds’ appearance, solubility, molecular weight, safety, and purity. Regarding purity, the monograph will contain details regarding suitable testing assays and the acceptable outcomes established by the publishing body. The US Pharmacopoeia (USP.org) claims that monographs aim to help in quality control. Various standards bodies, such as the American Chemical Society (ACS) and the United States Pharmacopoeia (USP), provide chemical monographs. As an example of what a monograph looks like, we can discuss one of sodium formate grades and its monograph. You can find the product description in the first line, including its commercial name. There is also a separate subsection for this grade’s intended applications based on its composition and chemical and physical properties. You can also find a detailed table about the grade’s specifications. Each grade of sodium formate may contain a specific amount of the following substances.
- Sodium formate content;
- Water content;
- Organic substances;
- Iron content.
As such, by checking the monograph of the sodium formate grade, you can find crucial information about its purity, chemical and physical properties, and intended applications. You can also learn about the famous qualities of this chemical compound that meet international standards below. Each of them will be suitable for a specific application, such as drilling mud or drilling salts.
Technical Grade
The technical grade of sodium formate is excellent for most industrial cleaning, degreasing tasks, and some solvent uses. However, they include a quantifiable level of contaminants that prevent them from being used in food or pharmaceutical applications.
ACS Grade
The ACS grade of sodium formate meets or exceeds the American Chemical Society’s purity criteria (ACS). This grade is suitable for food, drug, or medicinal use and can satisfy ACS applications or general procedures requiring stringent quality specifications and 95% purity.
Laboratory Grade
Although laboratory-grade sodium formate has a very high purity level, it contains a tiny amount of contaminants, making it unfit for food use. However, this chemical grade primarily appears in science projects and experiments for instruction or schools.
Sodium Formate Production Process
Sodium formate manufacturers produce this substance by using various methods and techniques. The final application, the intended amount of outcome, and the required purity are some of the crucial factors that help producers to choose one of the production processes. For instance, in order to produce sodium formate for industrial use, carbon monoxide is forced under pressure of 6-8 bar and 130 degrees Celsius into solid sodium hydroxide:
NaOH + CO = HCO2Na
Since formic acid can be produced cheaply and in large quantities by carbonylation methanol and hydrolyzing the ensuing methyl formate, sodium formate can be made by neutralizing formic acid with sodium hydroxide. Sodium formate is also generated as a byproduct in the final step of pentaerythritol synthesis and the crossing Cannizzaro reaction of formaldehyde with the aldol reaction, resulting in trimethylol acetaldehyde.
In this section, we will discuss a single-step procedure for generating highly pure sodium formate. More specifically, it proposes a method for manufacturing sodium formate aqueous solution constantly and efficiently in a tower-style reactor. Below, you can discover more about this production method that leads to making a pure grade of this product, suitable as sodium formate oilfield drilling and sodium formate drilling mud.
The Apparatus
The equipment used in the current method is a tower-type reactor, preferably an empty tower. An empty tower is helpful because it allows for high reaction speeds and efficient mixing of the components, increasing the flow rate per hour and sodium formate purity. To avoid counter mixing of the generated sodium formate, attaching a suitable device, such as perforated plates, in the reactor is advisable. However, the number of plates and plate spacing should be reasonable.
The Requirements
To ensure that the gas makes contact with sodium hydroxide and a perforated area, it is preferable to introduce the gas in as few tiny bubbles as feasible. When sodium hydroxide overflows with carbon monoxide, a suitable device for gas-liquid separation is installed after the gas-liquid outlet. The reaction occurs at a temperature between 150° and 220°C under a pressure of 12–30 kg/cm2. Lower temperatures and pressures above 150°C and 12 Kg/cm2 slow down reactions, respectively, whereas temperatures above 220°C are likely to lead to equipment corrosion.
Some must be removed if inert gas, such as nitrogen, is present in the excess gas separated from the sodium formate solution after the reaction. The remaining gas is then recirculated to the reaction tower with carbon monoxide supplied and consumed to react with sodium hydroxide. When using 100% carbon monoxide, the extra gas can naturally circulate in whole volumes.
The Outcome
To create a 45–55% aqueous solution of sodium formate, a flow of sodium hydroxide is less than two l./hr. Per effective unit, volume is industrially preferred, even though this flow might vary considerably. If the flow exceeds the cited number, high-purity sodium formate cannot be produced. It is safe to use more carbon monoxide than the theoretical amount determined by the amount of sodium hydroxide, and more carbon monoxide than 80% surplus may be used to create a highly pure sodium formate solution. The gas mixing and response speed are reduced if less than 50% excess carbon monoxide is used over the theoretical amount.
Sodium Formate Applications
Due to its numerous industrial and commercial uses, sodium formate manufacturers produce this substance in vast quantities. It is vital to note that all of these applications involve this substance’s chemical and physical properties, introduced in the previous sections. The salt is used to manufacture various compounds, such as sodium hydrosulphate and formic acid. Commercial applications for sodium formate include tanning leather, industrial printing, de-icing, food preservation, and detergent production. It also serves as a vital substance as a powerful Oil and Gas Chemical. Aside from this, Sodium formate can be employed as a cryoprotectant in structural biology for X-ray diffraction research on protein crystals, typically carried out at a temperature of 100 K to minimize the effects of radiation damage. All in all, sodium formate plays a role in the following:
- Dyeing Fabrics:
Salt is a fixing agent for dyes, mainly when dying fabrics are composed of polyester and cotton blends. As a fixing agent in printing processes, it performs a similar function. This salt aids the improved adhesion of printing inks to many substrates, especially textiles.
- Cryoprotectant:
It is utilized in this case to safeguard biological materials through X-ray diffraction tests on protein crystals. The temperature used for these studies is typically 100 K (-173.15°C).
- Food Additive:
It mainly goes into animal feeds as a preservative to help the food stay fresher longer. It is the E237 food additive number.
- Manufacturing Chemicals:
This salt is a crucial starting point and component in the large-scale manufacture of several compounds, including formic acid.
Below, you can read more about sodium formate applications in various industries.
Sodium Formate in Oilfield Drilling
Different grades of sodium formate can be used as drilling salts. (Additive materials in sub-drilling.) Saturated sodium formate solutions (as well as blends of other alkali metal formates, including potassium and cesium formate) are proper drilling and stabilizing aids in gas and oil exploration due to their relatively high density. Combining saturated alkali metal formate solutions can set any density between 1,0 and 2,3 g/cm3. The saturated solutions are long-lastingly stable against microbial deterioration and biocidal. On the other hand, when diluted, they degrade quickly and thoroughly. Formates are a significant advancement in exploration technology since they eliminate the need for solid fillers to improve density (like barytes) and allow the formate solutions to be recovered and repurposed on the drilling site.
Sodium Formate As a Buffering Agent
Sodium formate also serves as a buffering agent for strong mineral acids to raise their pH and as a food additive. The pH of solutions is frequently stabilized in soft matter and biological sciences using buffering agents. They can interact electrostatically with charged surfaces such as biomembranes and are typically made up of weak acids and bases combined with water. Buffers can cause protein aggregation and soft interface structural alteration, although a molecular-level understanding needs to be included.
Sodium Formate As a De-icing Agent
When combined with corrosion inhibitors and other additives, solid sodium formate acts at airports as a non-corrosive de-icing agent for runways. It quickly penetrates thick snow and ice layers, separates them from the asphalt or concrete, and melts the ice soon. It is interesting to know that from 1987 to 1988, Ottawa’s city roads were cleared of ice using sodium formate.
The high freezing point depression efficiently avoids the re-icing, even at temperatures below 15 °C, unlike the still widely used urea (which is effective but troublesome because of eutrophication). Moistening the solid sodium formate with aqueous potassium formate or potassium acetate solutions can enhance the thawing effect. When compared to the de-icing chemicals sodium acetate (740 mg O2/g) and urea with (> 2,000 mg O2/g), sodium formate’s degradability has a chemical oxygen demand (COD) of 211 mg O2/g.
