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

因为反应是由试剂的附而开始的，所以这个成反应。

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

本文利用三氯化铝作催化剂,废聚苯乙烯与溴发生取代反应合成溴化聚苯乙烯阻燃剂。
