Abstract
A mixture of alkali metal formates liquid at the reaction temperature, i.e. below 250 DEG C., is used in the dehydration of ethylenecyanhydrin to acrylonitrile. The process may be continuous and the formation of resinous byproducts is avoided. Sodium, potassium and lithium formates are mentioned. The catalyst remains active over a longer period if formic acid or ammonium formate is added.
