FIELD: chemical technology. SUBSTANCE: desalting is carried out by extraction treatment with water at countercurrent regime at 10-90 C and mass ratio resin : water = 1:(0.3-1.3). Method is used for processing waste in phenol and acetone production by cumene procedure, for removal of water-soluble salts from phenolic resin. EFFECT: improved method of desalting. 1 tbl
