【摘要】 以α-甲基苯乙烯(α-MS)为原料,以阳离子交换树脂、活性白土等为催化剂分别合成了α-MS环二聚体,线性2~3聚体,5~8聚体,2.4-二苯基-4-甲基-戊烯-(1)等化合物。以阳离子交换树脂为催化剂,催化剂用量为原料质量的5%,140℃,反应时间4 h,得α-MS环二聚体,收率87.2%,并以MS、IR、NMR测试技术表征了化合物结构。更多还原

【Abstract】 The α-methylstyrene cyclic dimer,liner dimer～trimer,pentamer～octamer, and 2,4-diphenyl-4-methyl-amylene-(1) were synthesized from α-methylstyrene(α-MS) with activated clay or strong acidic cation exchange resin as catalyst.With strong acidic cation exchange resin as catalyst,the reaction temperature was 140 ℃,the quantity of catalyst was 0.05 times as much as the (amount) of α-MS,and the reaction time was(4 h),the yield of α-MS cyclic dimer was 87.2%.The structure of the products was determined by IR,MS and NMR.更多还原
