Zeolite catalysts have been tested for alkylation of benzene with propylene to produce cumene and cymene from toluene by alkylation with propylene. Conditions of reaction were optimized with certain rare-earth-modified zeolites to give 75-80% cumene yields. Previous papers in this series have been concerned primarily with alkylation of benzene or toluene with methanol or ethylene. The latter reagents are very active under alkylating conditions and will oligomerize and react to give a variety of undesired by-products. Five to ten molar excesses of the aromatic component are needed to promote the desired alkylation reaction. Propylene is also very active and requires a similar excess of the aromatic component. In addition, there is potential for production of n- and isopropylbenzene. The results from alkylation of benzene with propylene using HZSM-5 are discussed here. 15 references.
