Process for alkylating aromatics |
abstract |
A process for alkylating aromatics is provided which comprises contacting an aromatic-containing feed with alkylating agent in the presence of a silica-bound ZSM-5 zeolite catalyst, wherein the ZSM-5 has a crystal size no greater than 0.05 micron, said contacting being conducted under alkylating conditions to provide a product containing a monoalkylated aromatic fraction and a polyalkylated aromatic fraction, wherein the polyalkylated aromatic fraction contains at least 40 wt.% of the para-dialkylaromatic species. The polyalkylated aromatic fraction may be contacted with unsubstituted aromatic and a transalkylation catalyst under transalkylating conditions to provide a monoalkylated aromatic-rich stream, e.g., an ethylbenzene-rich stream. |
