摘要:
The invention relates to a process for producing a desired dialkylbenzene isomer having a formula R2C6H4, where R is an alkyl substituent, by contacting a polyalkylbenzene compound of formula RnC6H6-n, where n is an integer between 2 and 4, with a monoalkylbenzene compound of formula RC6H5 in the presence of a molecular sieve catalyst under reaction conditions sufficient to produce said dialkybenzene isomer. The preferred molecular sieve catalysts have pores or surface cavities greater than 5.6 Angstroms in diameter and/or an X-ray diffraction pattern including d-spacing maxima at 12.4±0.25, 6.9±0.15, 3.57±0.07, and 3.42±0.07 Angstrom.
