Abstract

1530430 Linear dimers of styrene or substituted styrenes MONSANTO CO 31 May 1977 [1 June 1976] 22887/77 Heading C5E Styrene or substituted styrenes are converted to predominantly linear dimers by contact with a clay catalyst in the presence of a reaction modifier comprising an aldehyde, ketone, hydroxy ester or alcohol. The feed should be refined and comprises a monomer of the Formula I wherein m, n and p are each 0 to 3. The reaction may be carried out at 50-100‹ C. using montmorillonite or attapulgite clay. Examples describe the dimerization of α-methyl styrene to give 2,4- diphenyl-4-methyl-1-pentene and 2,4-diphenyl-4- methyl-2-pentene using a wide variety of reaction modifiers.
