间/对-二乙炔基苯的合成工艺研究

The synthesis process of a/p-diethyl benzene

以间/对二乙烯基苯为原料,经溴化加成反应得到二(α,β-二溴乙基)苯,再将分离后的二(α,β-二溴乙基)苯在甲醇钠/甲醇介质中脱去溴化氢,通过加水萃取和水蒸气蒸馏,得到纯度较高的间/对二乙炔基苯。

to room/divinyl benzene as raw material,through bromination addition reaction under two(alpha,beta 2 bromomethyl) benzene,then after separation of 2(alpha,beta 2 bromomethyl) benzene in sodium methoxide/methanol medium remove hydrogen bromide and through water extraction and vapor distillation,get high purity/between the two ethinyl benzene.
