Abstract

Un composto alchilaromatico viene selettivamente fotoclorurato in catena laterale in un sistema di reazione ciclico nel quale detto composto viene fatto circolare continuamente tra un recipiente di contenimento ed un reattore di fotoclorurazione.Il composto viene clorurato parzialmente ad ogni passaggio del reattore di fotoclorurazione, il numero di passaggi essendo dipendente dall'entità di clorurazione desiderata.Il procedimento è particolarmente utile per la preparazione di cloruro di benzile, cloruro di benzale e benzotricloruro, e dei corrispondenti derivati alogeno-sostituiti nel nucleo.
