Read： 523 Time：18months ago Source：Transform the World with Simplicity

Methyl isobutanol (MIBC) is a common organic chemical with high volatility and solubility, which can be widely used in flotation, separation, extraction and other industrial fields. There are many kinds of production processes and preparation methods of MIBC, including normal temperature and pressure hydrogenation preparation method, catalytic hydrogenation method, direct isomerization method, etc., the following will introduce and analyze these methods one by one.

Hydrogenation Preparation Method 1. Normal Temperature and Pressure

This method uses isobutylene as a raw material and carries out hydrogenation reaction using a metal catalyst at ambient temperature and normal pressure to obtain methylisobutanol. This method has simple raw materials, convenient operation, and high product purity, but the reaction time is long, the yield is low, and a large amount of hydrogen is consumed, so the production cost is high.

2. catalytic hydrogenation method

This method also uses isobutylene as raw material, but it is different from the normal temperature and normal pressure hydrogenation preparation method in that under the action of a catalyst, hydrogen oxide reacts with isobutylene to generate methyl isobutanol by pressurization. This method can effectively shorten the reaction time, improve the yield and reaction efficiency, but the reaction conditions need to be strictly controlled, and the selection and performance optimization of the catalyst have a great influence on the reaction.

3. direct isomerization method

This method is through formaldehyde and isobutene as raw materials, through acidic or alkaline catalyst to initiate isomerization reaction, and finally get methyl isobutanol. This method has high reaction efficiency and yield, and the reaction time is also short, but it also needs to select the catalyst and adjust the reaction conditions.

summary, there are many production processes and preparation methods of MIBC, and each method has its unique advantages and disadvantages. According to different needs and reaction conditions, choosing the appropriate method can improve reaction efficiency and reduce production costs.
