FIELD: chemistry.
SUBSTANCE: claimed invention relates to method of obtaining bisphenol-A by interaction of phenol and acetone in presence of solid acid catalyst, in particular ion-exchange resin, and inert stripping agent (versions). One of method versions includes reaction of phenol and acetone with formation of bisphenole-A and water with anti-current and multi-stage contact with solid acid catalyst in presence of means for stripping, boiling within range from 50 to 90°C in conditions of condensation pressure, and which is inert in reaction conditions, as a result of which means for stripping removes water from reaction medium, and acetone dissolves in phenol.
EFFECT: ensuring of catching of practically all acetone in reaction zone and reaching almost 100% conversion.
