Process for manufacturing alkenyl compounds

A process for manufacturing an alkenyl compound which comprises reacting an alkylbenzene and 1,3-butadiene in the presence of metallic sodium or a combination of metallic sodium and an oxide, a hydroxide, or a salt of potassium, rubidium or an alkaline earth metal, or a mixture of these under a pressure of 1 kPa (gauge) to 30 MPa (gauge). The process can produce alkenyl compound which is an industrially valuable compound as a raw material for the manufacture of naphthalenedicarboxylic acid, a highly useful raw material of polymers, at a high yield using a small amount of metallic sodium.

Process for producing alkenylbenzene

In a process for producing an alkenylbenzene by the reaction of an alkylbenzene having 8 or more carbon atoms and a conjugated diolefin, the improvement in which the reaction is performed in the presence of a catalyst obtained by dispersing (a) an alkali metal and (b) potassium carbonate and/or potassium hydroxide in the presence of (c) an aromatic hydrocarbon having at least a substituent with a double bond.
