Catalytic alkylation of benzene by alkenes in the vapor phase 2. Alkylation of benzene by 3-methyl-1-butene

  • 55 Accesses

Summary

  1. 1.

    Optimum conditions were found for alkylation of benzene with 3-methyl-1-butene under which the alkylate yield was 18.6% based on benzene used for the reaction and 74% based on the alkene.

  2. 2.

    2-Methyl-2-phenylbutane is formed instead of the expected 2-methyl-3-phenylbutane and 2-methyl-4-phenylbutane in the alkylation of benzene with 3-methyl-1-butene.

  3. 3.

    3-Methyl-1-butene isomerizes into 2-methyl-1-butene and 2-methyl-2-butene at 350° and a pressure of 40 atmospheres.
