HYDROGENATION OF 4-ACETOXYACETOPHENONE IN PRESENCE OF NO SOLVENT IN PRODUCTION OF 4-ACETOXYYSTYRENE, POLYMER THEREOF AND HYDROLYSATE THEREOF |
摘要 |
A process for the solventless (neat) hydrogenation of 4-acetoxyacetophenone to produce 4-acetoxyphenyl methylcarbinol. The reaction proceeds by heating at 54<o>C to 120<o>C 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). |
