METHOD FOR PRODUCING 1,3,5-TRIMETHYLBENZENE

摘要

PROBLEM TO BE SOLVED: To produce 1,3,5-trimethylbenzene from a mixture of trimethylbenzene isomers containing ethyltoluene.;SOLUTION: 1,3,5-Trimethylbenzene is produced from a mixture of trimethylbenzene isomers containing ethyltoluene in high efficiency by a step to perform at least one of deethylation reaction, hydrogenative deethylation reaction and transalkylation reaction of ethyltoluene and the isomerization reaction of trimethylbenzene and a step to separate the 1,3,5-trimethylbenzene by adsorption.;COPYRIGHT: (C)2002,JPO
