Nature:
Secondary butanol is a colorless liquid that has an alcoholic odor and is soluble in water and most organic solvents. The chemical properties of secondary butanol are relatively stable, and it is not easy to oxidize itself.
Purpose:
Secondary butanol is widely used in industrial and chemical laboratories. It is an important solvent used in the manufacture of coatings, cleaners, resins, dyes and lubricants. Secondary butanol can also be used as an oxidizing and reducing agent in organic synthesis reactions.
Preparation:
There are two main ways to prepare secondary butanol:
1. Prepared by the water and reaction of butene. At high temperatures, butene reacts with excess water vapor to form 2-butanol.
2. Obtained by hydrogenation reduction reaction of butyraldehyde. In the presence of hydrogen, butyraldehyde is reduced to 2-butanol by hydrogenation.
Colorless transparent liquid with a special aroma like wine. Soluble in ethanol, ether and other organic solvents, slightly soluble in water.
It can be obtained from acetaldehyde shrinkage and dehydration to crotonaldehyde, which is obtained by catalytic hydrogenation. Or grain starch as raw material, by fermentation, separation.
