IMPROVED ALKYLAROMATIC PRODUCTION PROCESS

摘要

The present disclosure provides a process for selectively producing a des ired monoalkylated aromatic compound comprising the step of contacting in a reaction zone an alkylatable aromatic compound with an alkylating agent in t he presence of catalyst comprising a porous crystalline material under at le ast partial liquid phase conditions, said catalyst manufactured from extruda te to comprise catalytic particulate material of from about 125 microns to a bout 790 microns in size, having an Effectiveness Factor increased from abou t 25% to about 750% from that of the original extrudate, and having an exter nal surface area to volume ratio of greater than about 79 cm-1.
