摘　　要：以丙烯腈为原料，经催化氯化、消除、蒸馏等步骤制得2-氧丙烯腈。对催化剂的选择，原料的用量，阳聚剂，反应温度，搅拌速度等进行了探讨。收率达到92.％产品沸点88℃～89℃。Using acrylonitrile as the starting reagent, 2-chloroacrylonitrile （vas prepared in several reaction steps including catalytic chlorination, clean-up, and distillation. Research was conducted to determine reaction parameters including catalyst selection, userate of the starting reagent, selection of polymerization re, tardant, reaction temperature, and stirring speed. Product yield was 92.6% and the boiling point was 88-89℃.
