Dimerization of 1,3-butadiene was investigated in a closed batch system under high-pressure conditions. 4-Vinylcyclohexene was mainly produced without using any solvents or catalysts at temperatures of 150–215 °C. The conversion of 1,3-butadiene was significantly dependent on the temperature and pressure. 1,3-Butadiene was converted to 4-vinylcyclohexene at selectivity higher than 90 mol % with by-products of 1,5-cyclooctadiene and 1,2-divinylcyclobutane. Large charges of reactant are efficient in achieving high conversions of 1,3-butadiene. Use of solvents, which dilute the reactant and absorb the reaction heat, is not favorable in the present dimerization of 1,3-butadiene under pressured conditions.
在高压条件下,我们对封闭批次系统中1,3-丁二烯的二聚作用进行了研究。在150-215°C的温度下,主要生成了4-乙烯基环己烯,且未使用任何溶剂或催化剂。1,3-丁二烯的转化率显著依赖于温度和压力。1,3-丁二烯以高于90摩尔%的选择性转化为4-乙烯基环己烯,副产品为1,5-环辛二烯和1,2-二乙烯基环丁烷。大量的反应物有利于实现1,3-丁二烯的高转化率。在本高压条件下的1,3-丁二烯二聚作用中,使用稀释反应物并吸收反应热的溶剂是不利的。
