COMPOSITION FOR PRODUCING CATION-EXCHANGE FIBRE MATERIAL Russian patent published in 2012 - IPC C08L61/10 C02F1/42 C08J5/20 

FIELD: chemistry.

SUBSTANCE: composition is meant for producing cation-exchange fibre material used in water treatment processes and treatment of industrial sewage. The composition is also used to soften and desalinate water, in production of synthetic detergents, in the paint industry and industry of polymer materials. The composition consists of paraphenol sulphonic acid and formalin. The composition additionally contains filler - basalt wool. The basalt wool is first heat treated for 1 hour at temperature 350-450°C, followed by microwave treatment at 180 or 750 W for 30 s. Content of components is as follows, wt %: paraphenol sulphonic acid 50-55.8, formalin 40.9-35.1; basalt wool 9.1. The composition enables synthesis of cation-exchange fibre material with improved properties, particularly lower oxidation number of the filtrate, higher specific volume of the cationite, as well as high dynamic exchange capacity and high osmotic stability of the cationite.

EFFECT: composition enables synthesis of cation-exchange fibre material with improved properties.
