Process for preparing unsaturated organic compounds.

摘要

A process is provided for obtaining improved yields of unsaturated organic compounds, particularly amides, acids and esters, at lower reaction temperatures which comprises reacting a reaction mass comprising sulfuric acid of over 96% strength with cyanohydrin and contacting the reaction mass with organic nitrile, the mole ratio of cyanohydrin:nitrile being from 2:1 to 100:1. The mitrile dehydrates the reaction mass, thereby suppressing the formation of undesired by-product, and by appropriate choice of the nitrile used, is capable of converting already formed undesired by-product to the desired unsaturated organic compound.
