Method of Obtaining Phenol-Furfural Resins

Abstract

Invention relates to improvement of method of obtaining phenol- furfural resins, utilized in different branches of national economy as cationites (for purification of waste water from ions of calcium, magnesium, etc., sorption of different metals). Method of obtaining phenol-furfural resins by polycondensation of sulfonated phenol with furfural is known; obtained in this case resin has small exchange capacity, low swelling, insufficient strength, which causes low quality of cationites. Target of present invention is improvement in mechanical properties of phenol-furfural resins and increase in its exchange capacitance.
