摘要
以β-月桂烯为原料,经Diels-Alder反应和酯化反应,合成了化合物4-(4-甲基-3-戊烯基)-4-环己烯-1,2-酸异辛酯。对酯化反应条件进行了优化,优化后条件为:在回流温度下,以B酸性离子液体[HSO3-bmim]+[HSO4]-做催化剂,催化剂的质量分数为0.7%,反应时间为80 min,n(酸酐)∶n(异辛醇)为1∶4.0,带水剂甲苯的质量分数为15%。该化合物可作为PVC塑料的主增塑剂使用,具有比邻苯二甲酸二(2-乙基己基)酯(DOP)更加优异的增塑性能。
Bis ( 2-ethylhexyl)-4-( 4-methylpent-3-enyl ) cyclohex-4-ene-1, 2-dicarboxylate is prepared by the reaction of Diels-Alder and esterification using fl-myrcene as raw materials. The optimal conditions of esterification are found as follows:with Bronsted acid ionic liquids [ HSO3-bmim] + [ HSO4 ]- as the catalyst,0. 7% of the amount of catalyst based on the total weight, 80 minutes of reaction time at refluxing temperature, 1 : 4.0 of n ( anhydride ) : n ( isooetanol) , 15% toluene based on anhydride and/so-octanol. The compound can be used as the primary plasticizer for PVC plastic with superior performance than that of the DOP.
