Abstract
A process for the selective alkylation of substituted or unsubstituted benzene compounds with relatively long chain length alkylating agents to produce phenylalkanes having an improved yield of the 2-phenylkane isomer. The reaction is carried out in the presence of crystalline zeolite catalysts characterized by channels or networks of pores having openings with a major dimension of 6-7 angstroms.
Claims11
A process for the selective alkylation of an aromatic compound with a relatively long chain length alkylating agent to produce linear phenylalkanes enriched in the 2-phenylalkane isomer;
- said alkylating agent comprising an aliphatic or aromatic organic compound having one or more available reactive alkyl groups of at least five carbons in the linear hydrocarbon chain;
- said process comprising contacting said aromatic compound with said alkylating agent in the presence of a selective zeolite catalyst at a temperature of between about 50.degree. C. and about 500.degree. C. and a pressure within the approximate range of 2.5.times.10.sup.4 N/m.sup.2 to 2.5.times.10.sup.7 N/m.sup.2 ;
- said selective zeolite catalyst being characterized by a crystal structure having channels or network of pores therethru, the major dimension of the openings to said channels or networks of pores being between about 6 and about 7 angstroms.
