In this paper, bromized polystyrene flame retardant was synthesized by electrophilic substitution of waste polystrene with bromine using aluminium ehlorid as catalyst.

本文利用三氯化铝作催化剂,废与溴发生亲电取反应合成溴化燃剂。

Because the reaction is initiated by the attachment of an electrophile, the process is called an electrophilic addition reaction .

因为反应是由亲电试剂的附加而开始的，所以这个过程叫做亲电加成反应。
