摘要:选用具有丰富不饱和键的乌桕籽油为原料,并通过酯交换、异构化、D-A反应、酯化等反应对其改性合成了具有六元环结构的多酯类增塑剂-多碳一甲二辛酯。结果表明,将马来酸二辛酯与乌桕油甲酯在碘催化下可同步共轭与D-A反应,乌桕油甲酯与马来酸酐的物质的量之比为1∶0.7,反应温度在180℃,反应时间为3 h;其产品不仅对PVC具有较好的增塑性能,且热稳定性明显优于DOP。
Choose stillingia oil which has abundant unsaturated bond as raw material, adopt a series of reactions, such as transesterification, isomerization reaction, D-A addition, esterification reaction, synthesized an ester plasticizer plasticizer has six-caned construction-more carbon triearboxylic monomethyl-dioctyl ester. The results show that:Dioetyl maleic acid ester and Stillingia oil methyl ester can be synchronous conjugated with D-A reaction with iodine as catalyst, The ratio of the amount of substance of stillingia oil methyl ester and maleie anhydride is 1 : 0. 7, the reaction temperature at 180 ℃ ,reaction time is 3 h;thise plasticizer has better plasticizing effects on PVC ,and the thermal stability was better than DOP.
