Abstract
A process comprising the addition of a degradation inhibiting effective amount of an ammonium, alkali metal, alkaline earth metal or transition metal of oxidation number +2 salt of an aliphatic mono or dicarboxylic acid to a composition comprising a phenol and a bisphenol, the addition occurring prior to a procedure which subjects the bisphenol to substantial heat, said bisphenol produced from an acidic ion exchange resin catalyzed reaction of a phenol and a ketone or aldehyde.
Claims14
A process comprising the addition of a degradation inhibiting effective amount of an ammonium, alkali metal, alkaline earth metal zinc of oxidation number +2 salt of an aliphatic mono or dicarboxylic acid having no other functional groups and from two to about eighteen carbon atoms, inclusive, to a composition comprising phenol and bisphenol-A, the addition occurring prior to a procedure which subjects the bisphenol to substantial heat, said bisphenol produced from an acidic ion exchange resin catalyzed reaction of phenol and acetone ketone or aldehyde.
A process in accordance with claim 2 wherein the salt is a salt of a monocarboxylic acid.
The process in accordance with claim 6 wherein the metallic portion the salt is sodium or ammonium.
A composition comprising phenol and bisphenol-A in admixture with a bisphenol-A degradation inhibiting effective amount of an ammonium, alkali, alkaline earth or zinc metal of oxidation number +2 metal salt of an aliphatic mono or dicarboxylic acid having no other functional groups and from two to about eighteen carbon atoms, inclusive.
