对直接溴化法合成六溴苯作了系统的研究,并对文献方法进行了一系列的改进。包括选择适当的摧化剂及其用量,使反应基本上在室温下进行;利用水汽蒸馏法驱除残余溴,可直接得到无色或近乎无色的纯净产物,而勿需进行还原脱溴,且得率较高。提出一种以溴化物形式回收副产物的方法。 The direct bromination of hexabromobenzene was systematically studied, and a series of improvements were made to the literature methods. Including the choice of an appropriate amount of catalyst and its amount to allow the reaction to proceed essentially at room temperature; the removal of residual bromine by steam distillation directly yields a clear or nearly colorless, pure product without the need for reductive debromination and Higher yield. A method of recovering by-products in the form of bromide is proposed.
