| titleOfInvention | Production of polyalkylbenzene |
| abstract | PURPOSE: To produce the titled compound on an industrial scale at a low cost, by alkylating a di- or trialkylbenzene in the presence of hydrogen using a catalyst comprising crystalline aluminosilicate modified with a heteropolyacid. n CONSTITUTION: A polyalkylbenzene, especially trimethylbenzene and tetramethylbenzene is produced by reacting an aromatic compound containing dialkylbenzene and/or trialkylbenzene with an alkylation agent, especially methanol and/or dimethyl ether in the presence of hydrogen using a catalyst comprising preferably a mordenite-type crystalline aluminosilicate treated with a modifying agent containing one or more compounds selected from heteropolyacid and its salt. The side reaction can be suppressed to improve the yield of the objective compound, facilitate the separation and purification of the compound and keep the catalytic activity stably over a long period. n COPYRIGHT: (C)1988,JPO&Japio |
