AROMATIC ALKYLATION PROCESS |
摘要 |
In a method for producing monoalkylated aromatic compounds, an aromatic feed is contacted with an alkylating agent in the presence of a catalyst comprisi ng a molecular sieve having an X-ray diffraction pattern including d-~spacing maxima at 12.4.plusmn.0.25, 6.9.plusmn.0.15, 3.57.plusmn.0.07, and 3.42.plusmn.0.07 Angstrom. The catalyst also contains at least one metal cation selected from Groups 1-4 and 7-16 of the Periodic Table of Elements, wherein the metal cation is present in an amount of at least 0.5% by weight of the catalyst, whereby selectivity of the catalyst to produce monoalkylates over polyalkylates is improved as compared with the identical catalyst but without the metal cation present.
