In the technology of synthesis of an additive for drywall based on polymethylene naphthalenesulfonate, it is proposed to carry out an additional stage - the Cannizzaro reaction, which allows reducing the mass fraction of residual formaldehyde. In the process of experimental studies, the effect of the additive on the plasticizing properties of the gypsum dough was revealed.
