There is provided a method for preparing para-divinylbenzene by dehydrogenating para-diethylbenzene followed by crystallizing para-divinylbenzene. The para-diethylbenzene may be prepared by alkylating ethylbenzene with ethylene in the presence of a para-selective molecular sieve catalyst, such as ZSM-5 modified with an oxide of magnesium and, optionally, an oxide of phosphorus.
