ISOMERIZATION OF NONCONJUGATE DOUBLE BOND IN REACTANT COMPRISING CONJUGATE DIOLEFIN AND AROMATIC HYDROCARBON TO CONJUGATE DOUBLE BOND

摘要

The process is carried out with the aid of an isomerisation catalyst and, if appropriate, in the presence of a solvent, the isomerisation catalyst employed being an alkali metal alkoxide, if appropriate together with a strongly polar aprotic compound, or a reaction product and/or mixture of an alkali metal and/or an alkali metal hydride and/or an organic alkali metal and/or organomagnesium compound and ammonia and/or an amine and/or hexamethylphosphoric triamide and the isomerisation being carried out at temperatures from 0 to + 200 DEG C.
