Title:
アルキル芳香族化合物の製造方法
Document Type and Number:
Japanese Patent JP5417449
Kind Code:
B2
Abstract:
In a process for alkylation of an alkylatable aromatic compound to produce a monoalkylated aromatic compound, a first feed stream comprising fresh alkylatable aromatic compound is passed to a first reaction zone which comprises a transalkylation catalyst and which also receives a second feed stream comprising polyalkylated aromatic compounds. The first and second feed streams are contacted with the transalkylation catalyst in the first reaction zone under conditions to transalkylate the polyalkylated aromatic compounds with the alkylatable aromatic compound to produce the desired monoalkylated aromatic compound. A first effluent stream comprising unreacted alkylatable aromatic compound and the monoalkylated aromatic compound is removed from the first reaction zone and passed to a fractionation system to separate the first effluent stream into a first light fraction comprising the unreacted alkylatable aromatic compound and a first heavy fraction comprising the monoalkylated aromatic compound. At least part of one or more impurities in the fresh feed stream are removed in the first reaction zone.
