为了满足激光惯性约束聚变(ICF)中对全氘代聚合物泡沫的需求,2003年主要利用非氘代化合物对制备全氘代聚合物泡沫所需的全氘代单体———氘代二乙烯基苯的合成路线进行了相应的探索研究。根据制备成本,最终产物产率以及影响最终氘代率等因素,基本确定了合成氘代二乙烯基苯的路线,即:以氘代对二甲苯为原料,通过溴代,水解和魏希梯(Witting)烯化三步反应,进行氘代二乙烯基苯合成。目前非氘代二乙烯基苯已经制备成功,并对一些中间氘代物也进行了相应制备。 In order to meet the demand for fully deuterated polymer foams in laser inertial confinement fusion (ICF), in 2003 the main use of non-deuterated compounds for the preparation of fully deuterated polymer foam required deuterated monomer deuterated bis Vinylbenzene synthesis route for the corresponding exploration. According to the preparation cost, the yield of the final product and the final deuteration rate and other factors, the route of synthesizing deuterodivinylbenzene is basically confirmed, that is, the deuterated para-xylene is obtained by bromination, hydrolysis and Weixi ladder (Witting) olefination three-step reaction, deuterated divinylbenzene synthesis. At present, non-deuterated divinyl benzene has been successfully prepared, and some intermediate deuterated products have also been prepared accordingly.
