PROCESS FOR PREPARING AROMATIC PRODUCT WITH ALKYLATING ZEOLITE AND DEALKYLATING ZEOLITE

Process for preparing an alkylated aromatic product (12) by alkylation of an aromatic compound (1), the alkylation giving a number of alkylated aromatic products, this process being characterised by the following points: a) the aromatic compound (1) is reacted with an alkylating agent (2) in the p...

Zusammenfassung:	Process for preparing an alkylated aromatic product (12) by alkylation of an aromatic compound (1), the alkylation giving a number of alkylated aromatic products, this process being characterised by the following points: a) the aromatic compound (1) is reacted with an alkylating agent (2) in the presence of an alkylation zeolite (4); b) the alkylated aromatic product (12) is separated from the alkylation products by crystallisation; c) the uncrystallised part (13) of the alkylated aromatic products is subjected to a dealkylation in the presence of a dealkylation zeolite (15); d) the regenerated aromatic compound (1b) is recycled to make it react again with the alkylating agent (2) in the presence of the alkylation zeolite (4). Alkylated aromatic compounds (12) obtained by this process, especially 2,6-dicyclohexylnaphthalene.
