ABSTRACT:
Process for the production of 2,2-(4,4'-dihydroxydiphenyl) propane comprising reacting phenol with acetone in a molar ratio of at least 2:1 but not exceeding 10:1 in the presence of an acidic agent at a temperature not exceeding 80.degree. C. to substantially complete reaction of the acetone, separating the acidic agent from the reaction product, bringing the product freed from acidic agent into contact with a material chosen from between activated carbon and active earths at a temperature in the range of from about 60.degree. to 120.degree. C. for a time in the range of from about 1 to 120 minutes and distilling the product obtained in the treatment with the active material to recover the 2,2-(4,4'-dihydroxydiphenyl-propane.
