Synthesis method

1. Brief description of the production method

It is obtained by chlorination of isobutyric acid to obtain isobutyryl chloride, and then amidation. Add isobutyryl chloride dropwise to concentrated ammonia water under strong stirring, and control the addition rate so that the temperature does not exceed 15°C. After the addition was completed, the mixture was stirred for another 1 hour, and the mixture was evaporated to dryness under reduced pressure. The residue was isobutylamide and ammonium chloride. Add ethyl acetate to the residue, boil for 10 minutes, filter, and then dry under vacuum to obtain the finished product.

Purpose

2. Uses

Used in organic synthesis,Prepare isobutyronitrile, etc.
