Procedure

In these experiments, cumene was manufactured by contacting 5.55 parts by weight benzene and 1 part by weight propylene in the batch slurry reactor using the procedure detailed above for Test Sequence for Cumene Manufacture in a Batch Test over catalyst comprising the 0.127 cm MCM-49 quadrulobal catalyst (Material 1) and the 250 to 297 micron catalyst prepared from it by crushing and sieving (Material 2). Cumene (isopropylbenzene, IPB) and diisopropylbenzene (DIPB) products were collected from each experiment and it was found that Material 2 again provided a 30% reduction in the DIPB/IPB ratio.
