Further information about Methyl Isobutyl Carbinol Production Process

European, American and Asian chemical producers, such as Iran manufacturers of Methyl Isobutyl Carbinol (MIBC), have developed various ways to produce MIBC. Several methods of producing this substance are similar to making other chemical solvents by employing specific machines and certain condensation and Dehydration processes. It is vital to note that Methyl Isobutyl Carbinol, like other chemical compounds, should be produced in the hand of experienced chemists to meet satisfactory results. So, it makes sense to rely on products of respected companies, like Iran’s producers of mineral processing chemicals.

This section contains a production process for the Methyl Isobutyl Carbinol. But, we should consider that this method would also be utilized for producing other solvents like a mixture of MIBC and IBHK plus TMN. In one aspect, the production process pertains to a method for creating trimethyl nonanol (TMN), isobutyl heptyl ketone (IBHK), and Methyl Isobutyl Carbinol (MIBC). In another aspect, it relates to a method for producing these solvents using a catalyst made of copper. The main point is that this technique enables chemists to deliver MIBC in its pure form or combined with a mixture of IBHK and TMN. Therefore, producers of various countries like Indian manufacturers of Methyl Isobutyl Carbinol (MIBC) can rely on this process to deliver other desired outcomes like a mixture of MIBC and IBHK plus TMN.

When MIBK is exposed to hydrogen under condensation-reactive conditions and in the presence of a catalytic quantity of a Cu-based condensation catalyst (a copper-containing catalyst), MIBC or a combination of IBHK and TMN is created. The reaction temperature determines the relative amounts of the outcome, whether it contains MIBC or a mixture of IBHK and TMN. Accordingly, with a lower temperature, such as 130 C,  MIBC would be produced and at a higher temperature, such as 200 C, it may result in a mixture of MIBC and IBHK plus TMN.

The Summary Of The Production Process

Mixed ketone converters are used to create MIBK, MIBC, DLBK, and IBHK simultaneously. The reaction system is fed isopropanol and hydrogen, and various products are produced through a sequence of condensation, hydrogenation, and dehydration stages. It is possible to perform these condensation, hydrogenation, and dehydration reactions using a single multifunctional catalyst made of copper, chromium, and calcium supported by aluminium oxide. These goods may be continuously manufactured in the amounts required. A small degree of product ratio adjustment is possible by changing the reaction conditions. Please also consider that the Refined MIBK created in the mixed-ketone converters is fed into a different single hydrogenation converter with a catalyst made of nickel to make further MIBC.

It is vital to understand that the term “condensation/hydrogenation/dehydration reactive conditions” represents particular reactive conditions employed in this production process. It means that some reactants undergo condensation and/or dehydration and/or hydrogenation. These reactive conditions indicate functions below:


It involves uniting two molecules or moieties to create a single molecule while losing a tiny molecule, for as, when two MIBK combine to make IBHK plus water.


It is the process of incorporating hydrogen into an unsaturated organic molecule, such as when changing MIMIC to MIBC.


It is a chemical reaction where one molecule loses water (it is a subset of elimination reactions), such as when DAA is converted to MSO.

A temperature between 90 and 300 C. and a pressure between 0.1 and 1 megapascals are required to achieve the best results from these three conditions in our intended process.

The Advantages Of This Process

When MIBK and hydrogen are fed over Cu-based hydrogenation or multifunctional catalyst (a copper-containing catalyst) at low temperatures, similar to those required for a Ni-based hydrogenation catalyst, MIBC is created. MIBC is manufactured in a converter employing costly materials like nickel-based catalyst during the standard techniques used by various producers like Indian and china manufacturers of mineral processing chemicals. The process described in this article allows for a significant increase in IBHK plus TMN production capacity. It happens by eliminating the need for other labour-intensive campaigns to supplement IBHK plus TMN production, using a much less expensive catalyst, reducing conversion costs, and finally, generating fewer hydrocarbon impurities. So, reducing production costs may allow Iranian distributors of Methyl Isobutyl Carbinol (MIBC) to represent their products at a reasonable price.

Details about the method expectations

The ideal catalysts for this process are bi-functional, copper-based aldol condensation catalysts that can also perform hydrogenation chemistry. Still, other copper-based catalysts can also be utilized. Considering this, any stimulus effective in manufacturing MIBK or DIBK from IPA and DMK may be applied in the conduction of this method. These catalysts frequently combine one or more base metals (such as Na, Ca, Mg, and Li) with one or more metals (such as Cr, Ni, Pd, or Zn) for hydrogenation and dehydrogenation chemicals. This capability helps various producers like Turkey manufacturers of Methyl Isobutyl Carbinol (MIBC) simplify the delivery process.
