对甲苯磺酸催化合成邻苯二甲酸二烯丙酯

Catalytic Synthesis of Diallyl Phthalate by p-Methylbenezesulfonic Acida

以对甲苯磺酸作催化剂,由邻苯二甲酸酐和烯丙醇反应合成邻苯二甲酸二烯丙酯。邻苯二甲酸酐与烯丙醇的物质的量比为1:4,对甲苯磺酸的质量为邻苯二甲酸酐质量的13%,回流分水16h,产品邻苯二甲酸二烯丙酯的收率可达95.7%。

Diallyl phthalate was synthesized from phthalic anhydride and allyl alcohol in the presence of p -methylbenezesulfonic acid. The yield of diallyl phthalate could reach 95.7% when the mole ratio of phthalic anhydride and allyl alcohol was 1：4 and p - methylbenezesulfonie acid was 13% of the mass of phthalic anhydride with refluxing and separating water for 16 h.
