反应详情

Upon cooling and reheating to 45° C., the reaction mixture remains viscous. Two hundred grams of 45° C. phenol are added and, upon stirring, the temperature rises to 50° C. The temperature is then lowered to 33° C. for formation of a 1:1 bisphenol-A/phenol molar adduct. Results of gas chromatographic analysis of the adduct thus formed shows 49% of the bisphenol-A present in the completed reaction mix is present in the adduct formed.
