H-mordenite has been shown to be unique in its ability to yield a high percentage of para-substitution of monoalkyl benzene by alkylation with long chain alpha-olefins. The process also yields a high percentage of substitution of the alpha-olefin in the 2-carbon position. Minimal side effects, such as dialkylation and transalkylation, are also advantages of the process.
