摘　　要：以三光气和丙烯酸为原料,在无溶剂及少量阻聚剂和一定量催化剂条件下,合成了纯度较高的丙烯酰氯。探讨了投料比、催化剂及其用量和反应时间对三光气法合成丙烯酰氯收率的影响,结果表明最佳的实验条件为:原料配比为2∶1,最佳催化剂为咪唑,反应时间为3.5 h。The high-purity acryloyl chloride was synthesized from triphosgene and acrylic acid without solvent.Only a small amount of inhibitor and a certain amount of catalyst were needed.The effect factors including reactant ratio,catalyst and its quantity,reaction time were discussed.The optimum experiment conditions were obtained： the molar ratio of triphosgene and propanic acid was 1∶ 2,the best catalyst was imidazole,and reaction time was 3.5 h.
