| Application | isobutyramide is an important organic synthesis monomer, used in organic synthesis, preparation of isobutyronitrile, etc. As a component of environment-friendly anti-spattering fluid for automobile welding, isobutyramide has a good prospect of technical application. |
| production method | isobutyryl chloride is obtained from isobutyric acid by chlorination followed by amidation. Isobutyryl chloride was added dropwise to concentrated aqueous ammonia with vigorous stirring, and the rate of addition was controlled so that the temperature did not exceed 15 °c. After the addition was complete, the mixture was stirred for 1H. The mixture was evaporated to dryness under reduced pressure and the residue was isobutyramide and ammonium chloride. Ethyl acetate was added to the residue, boiled for 10min, filtered and dried under vacuum to give the final product. |
