以间苯二酚和苯乙烯为原料,离子液体N-甲基吡咯烷酮硫酸氢盐([Hnmp]HSO4)为催化剂,经傅克反应催化合成标题化合物。通过正交实验进行条件优化,在n(间苯二酚)∶n(苯乙烯)=1.5∶1.0,催化剂n([Hnmp]HSO4)用量为2.5%,反应温度105℃,反应时间为6h条件下,产物收率达到85.7%。对产品进行了熔点测定、IR光谱分析、ESI-MS分析及1HNMR分析,确定合成的产物为目标产物。 The title compound was synthesized by Friedel-Crafts reaction using resorcinol and styrene as raw materials and ionic liquid N-methylpyrrolidone hydrogensulphate ([Hnmp] HSO4) as catalyst. The conditions were optimized by orthogonal experiments. Under the conditions of n (resorcinol): n (styrene) = 1.5:1.0, catalyst n ([Hnmp] HSO4) 2.5%, reaction temperature 105 ℃ and reaction time 6h The product yield reached 85.7%. The melting point, IR spectrum, ESI-MS analysis and 1HNMR analysis of the product were carried out to determine the product as the target product.
