Abstract
A process for producing an alkylaromatic compound comprises providing a first feed comprising an alkylatable aromatic compound and a second feed comprising an alkylating agent, wherein at least the first feed contains an impurity compound comprising at least one of nitrogen, halogens, oxygen, sulfur, arsenic, selenium, tellurium, phosphorus, and Group 1 through Group 12 metals The first feed is passed through an adsorbent comprising a metal-organic framework material under conditions effective to reduce the amount of impurity compound in the first feed and produce a purified first feed. The purified first feed and at least part of the second feed are then contacted with an alkylation catalyst composition under alkylation conditions effective to convert at least part of the alkylatable aromatic compound in the purified first feed to the desired alkylaromatic compound and produce an alkylation effluent.
