FIELD: chemical industry.
SUBSTANCE: invention relates to a method for producing slightly acidic sorption and ion-exchange materials, including the interaction of amino-containing raw materials with technical formalin and phenol, and as an amino-containing raw material, a product of acid hydrolysis of animal proteins is used: organic acid dermis collagen hydrolysate with an amine nitrogen content of 50-84 mg, with a liquid hydrolysate coefficient of 8-14, conducted in an alkaline medium at a temperature of 80-90°C.
EFFECT: expansion of the range of solutions to obtain chemical substances.
