Abstract
Acrylonitrile was urgently required for certai experimental work and the Ministry of Supply Undertook the requiring a minimum of special equipment. The published methods of preparation were reviewed, together with certain information from B.I.O.S. reports on German industrial processes, and a process was finally developed suitable for existing plant. This paper deals with the laboratory and semiβtechnical research incidental to the preparation of about 56 1b. of acyrlonitrile starting from ethylene chlorhydrin.
