HETEROPOLYMER OF SALTS OF HEXAMETHYLENEGUANIDINE AND METHOD OF OBTAINING IT Russian patent published in 2008 - IPC C08G73/02 C07C277/08 C07C279/08 

FIELD: chemistry.

SUBSTANCE: invention relates to the heteropolymer salts of hexamethyleneguadinine and method for obtaining it, it is used as a means of disinfecting in medicine, veterinary science, for disinfection of natural and waste water, for protection of the materials of plant and animal origin, for example, of wood, cotton the skin, fur from biodegeneration, as well as in other sectors of national economy, where biocidal products are required. Heteropolymer salts of hydrochloride, phosphate and sodium dihydroorthophosphate of hexamethyleneguadinine of the following formula: , where: A=5-25 mol%; B=60-90 mol%; C=5-30 mol%, can be obtained in two ways. The first method of obtaining heteropolymer salts consists in adding and mixing up of the base of poly- hexamethyleneguadinine, dissolved in ethyl alcohol or in water, with hydrochloric acid, phosphoric acid and 30% aqueous solution of sodium dihydroorthophosphate, or with hydrochloric acid, phosphoric acid and aqueous sodium hydroxide. Then the obtained heteropolymer is separated and fried. Initial components are take in the following molar relationship base poly-hexamethyleneguadinine: hydrochloric acid: phosphoric acid: solution of sodium dihydroorthophosphate - 1: 0.05-0.25 : 0.60-0.90 : 0.05-0.30, or in the following molar relationship of the base poly- hexamethyleneguadinine: hydrochloric acid; phosphoric acid; solution of sodium dihydroorthophosphate - 1: 0.05-0.25 : 0.65-1.20 : 0.05-0.30. The second method of obtaining the heteropolymer salts consists in that to the hydrochloride of poly- hexamethyleneguadinine, dissolved in ethyl alcohol, alcoholic solution of sodium hydroxide obtaining the mother liquor, to which phosphoric acid and 30% aqueous solution of sodium dihydroorthophosphate is added while mixing. The obtained heteropolymer is dried. The initial components are put in the following molar relationship: hydrochloride of the poly- hexamethyleneguadinine; alcoholic solution of sodium hydroxide: phosphoric acid: solution of sodium dihydroorthophosphate - 1: 0.75-0.95 : 0.60-0.90 : 0.05-0.30.

EFFECT: invention enable to obtain heteropolymer salts with high antimicrobial activity.
