METHOD USED FOR MANUFACTURE OF THE FILTERING MEDIUM AND THE FILTERING MEDIUM Russian patent published in 2008 - IPC B01D39/16 

FIELD: chemical industry; other industries; methods of manufacture of the filtering medium.

SUBSTANCE: the group of inventions is pertaining to the field of the water treatment, to be exact to the manufacture process of the polymers of the space-globular structure (SGS polymers), used in the capacity of the filtering mediums. The method of manufacture of the filtering medium consists, that preliminarily exercise thiocyanation of resorcinol, then conduct the joint polycondensation of the resorcinol, the formaldehyde and the product of thiocyanation of the resorcinol. The filtering medium is characterized by the fact, that it contains the product of the joint condensation of the formaldehyde, resorcinol and the product of the reaction of thiocyanation of the resorcinol, and also that it has space- thiocarbomate functional groups-S-C (O)-NR₂ defined in the infra-red spectrum of absorption of the polymer sample by the bands with the minimums of 1163 cm^-1 (the reference band), 1720 cm^-1 (the reference band) and 615 cm^-1 (the ill-defined band).

EFFECT: the group of the inventions presents the method of manufacture of the polymers of the space-globular structure used in the capacity of the filtering mediums.
