ABSTRACT:
A process of recovering monoalkylbenzene and pure 1,3,5-trialkylbenzene from an isomeric mixture containing dialkyl- and trialkylbenzenes. The process comprises transalkylating a monocyclic aromatic compound with a mixture of dialkyl- and trialkyl-benzenes in the presence of an acidic mordenite zeolite under conditions such that monoalkylbenzene and predominantly 1,3,5-trialkylbenzene are formed. 1,3,5-trialkylbenzene is isolated in pure form from a mixture of the same and 1,2,4- and/or 1,2,3-trialkylbenzene by use of a dealuminated zeolite Y adsorbent.
