METHOD FOR SIDE CHAIN ALKYLATION OR ALKENYLATION

摘要

The invention relates to a method for reducing the formation of polymers during the side chain alkylation or side chain alkenylation of alkylaromatic compounds by reacting olefins or diolefins in the presence of an alkali metal catalyst; and the ensuing distillation for preparing the alkylated or alkenylated compound. The alkali metal in the catalyst is situated on an inorganic carrier, and the catalyst is mechanically separated from the reaction mixture after the reaction and before distillation.
