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开始的，所以这个过程叫亲电成反应。

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

本文利用铝作催剂,废聚苯乙烯与溴发生亲电取代反应合成溴聚苯乙烯阻燃剂。
