Method for selective dealkylation of 1,4-dialkylbenzene |
| 摘要 |
A method for selective dealkylation of 1,4-dialkylbenzene comprising selectively dealkylating a 1,4-dialkylbenzene in a dialkylbenzene mixture using as a catalyst crystalline zeolite having a silica/alumina ratio of at least 12 and a constrained index of 1 to 12 which is modified with an oxide of a metal or mettaloid, said crystalline zeolite being one ion-exchanged with a lithium ion.
