Production of N-t-alkylamides from t-olefins or t-alcohols.

摘要

A process for producing N-t-alkylamides comprises reacting a combination of a tertiary olefin and water, and/or a tertiary alcohol with a nitrile in the presence of sulfuric acid, with the molar ratio of sulfuric acid to the tertiary olefin and/or tertiary alcohol being 0.05:1 to 0.8:1 and the molar ratio of the nitrile to the tertiary olefin and/or tertiary alcohol being 1.5:1 to 10:1. The process gives good yields. Suitable reagents are isobutylene or isobutyl alcohol, and hydrocyanic acid.
