三(环氧丙基)异氰尿酸酯的合成

SYNTHESIS OF TRIGLYCIDYL ISOCYANURATE

采用2步法合成了三(环氧丙基)异氰尿酸酯(TGIC),研究了物料配比、催化剂、反应时间、反应温度、反应时真空度等对产率的影响,得到了如下工艺条件:采用四甲基氯化铵作催化剂,原料配比为:n(氰尿酸)∶n(环氧氯丙烷)=1∶18;第1步反应时间为6h;第2步反应时间为1 5h;第1步反应温度90℃;第2步反应真空度0 09MPa,产率95%以上。

Triglycidyl Isocyanurate(TGIC) was synthesized by two steps using.The rate of epichlorohydrin and cyanuric acid was 1∶18(mol).The reaction in the first step need 6 h at temperature of 90 ℃ and the second step need 1.5 h at vaccum condition.The process was satisfactory with high yield above 95% and little pollution of water.
