LOESUNGSMITTELFREIE HYDRIERUNG VON 4-ACETOXYACETOPHENON BEI DER HERSTELLUNG VON 4-ACETOXYSTYREN UND SEINEN POLYMEREN UND HYDROLYSEPRODUKTEN.

摘要

A process for the solventless (neat) hydrogenation of 4-acetoxyacetophenone to produce 4-acetoxyphenyl methylcarbinol. The reaction proceeds by heating at 54C to 120C with an excess of hydrogen in the presence of a Pd/C or activated nickel such as Raney Nickel catalyst in the absence of a solvent. The 4-acetoxyphenyl methylcarbinol may then be dehydrated to 4-acetoxystyrene. The later may be polymerized to poly(4-acetoxystyrene) and hydrolyzed to poly(4-hydroxystyrene).
