Abstract

1,262,942. Transalkylation. UNIVERSAL OIL PRODUCTS CO. 15 May, 1969 [16 May, 1968], No. 24768/69. Heading C5E. A transalkylation process comprises contacting an alkyl aromatic -hydrocarbon at 200- 480‹ C. and at a pressure of from atmospheric to 100 atmospheres with a catalyst comprising an acid extracted crystalline aluminosilicate. Examples describe the use of catalysts to convert (1) toluene to benzene (2) toluene and trimethylbenzene to xylenes (3) di- and tri-ethylbenzenes to benzene and (4) the various products up to C 16-18 which are produced after prolonged reaction of ethylbenzene.
