Abstract:
In a method for producing a monoalkylated aromatic product, benzene and an alkylating agent are contacted with an alkylation catalyst in a first alkylation reaction zone under alkylation conditions to produce a first alkylation effluent comprising the monoalkylated aromatic product, polyalkylated aromatic product, unreacted benzene and C5, C6 and/or C7 non-aromatic compounds. A purge stream containing C5, C6 and/or C7 non-aromatic compounds and unreacted benzene is removed from the first alkylation effluent and is contacted with an alkylating agent in a second alkylation reaction zone in the presence of an alkylation catalyst under alkylation conditions to produce a second alkylation effluent comprising monoalkylated aromatic product, polyalkylated aromatic product and C5, C6 and/or C7 non-aromatic compounds. The monoalkylated aromatic product is recovered from the first and second alkylation effluents and at least part of the C5, C6 and/or C7 non-aromatic compounds in the second alkylation effluent is purged.

Claim (Index 1):
A method for producing a monoalkylated aromatic product, the method comprising:\n (a) contacting benzene and an alkylating agent with an alkylation catalyst in a first alkylation reaction zone under alkylation conditions to produce a first alkylation effluent comprising the monoalkylated aromatic product, polyalkylated aromatic product, unreacted benzene and C 5 , C 6  and/or C 7  non-aromatic compounds; (b) removing a purge stream containing C 5 , C 6  and/or C 7  non-aromatic compounds and unreacted benzene from the first alkylation effluent; (c) contacting at least part of the purge stream with an alkylating agent in a second alkylation reaction zone in the presence of an alkylation catalyst under alkylation conditions to produce a second alkylation effluent comprising monoalkylated aromatic product, polyalkylated aromatic product and C 5 , C 6  and/or C 7  non-aromatic compounds; (d) recovering the monoalkylated aromatic product from the first and second alkylation effluents; and (e) purging at least part of the C 5 , C 6  and/or C 7  non-aromatic compounds in the second alkylation effluent.
