Abstract
1,052,618. Bis (4-hydroxyphenyl) propane. BALDWIN-MONTROSE CHEMICAL CO. Aug. 5, 1965, No. 33649/65. Heading C2C. 2,2 - bis (4 - hydroxyphenyl) propane is made by reacting acetone with at least 5 moles phenol, while HCl is introduced into the reaction zone at a rate sufficient to maintain a pressure above 3À5 kg/cm.<SP>2</SP> and a temperature up to 60‹ C. until the reaction is at least 90% complete and fractionally distilling off excess phenol followed by the product, under reduced pressure.
