INCORPORATED BIOCIDE Russian patent published in 2008 - IPC A01N25/30 A01N57/34 C02F1/50 C02F5/14 

FIELD: agriculture.

SUBSTANCE: invention refers to biocides based on phosphonium compounds incorporated in the matrix base. The phosphonium compound is selected from the group including tris(hydroxyorgano)phosphine (THP), THP⁺-salt (tetrakis(hydroxyorgano)phosphonium salt) or a condensation reaction product of THP with nitrogen compound, selected from the group consisting of urea, cyanotriamide, aminoethanamidine or dicyandiamide. Thus the matrix base represents multiatomic spirits with fusion temperature of 5-80°C, soluble in water at temperature of 5-100°C. THP⁺-salt can be a sulphate, chloride, phosphate, acetate or oxalate. In particular multiatomic spirit represents polyethylene glycol with molecular mass more than 600, for example, 8000. The incorporated biocide may also contain scaling inhibitors, corrosion inhibitors, additional biocides, demulsificators, inhibitors of the moisture containing in gas, inhibitors/dispersants of asphaltenes, surface-active substances, antifoaming agents, fragrance components, wax inhibitors, scum solvents, gelling materials, and oxygen absorbers. Offered phosphonous compound can be made in the form of pencils/candles, balls, pellets, bricks, a swaft, flakes or granules. Such biocides can be used with high efficiency for decreasing of amount of microorganisms in various industrial systems, and also for reduction of adjournment of a carbonate of iron and boil iron, lead and zinc, in aerated systems and when providing slow release of phosphonous compounds.

EFFECT: decrease of amount of microorganisms in various industrial systems, and also for reduction of adjournment of a carbonate of iron and boil iron, lead and zinc, in aerated systems and when providing slow release of phosphonous compounds.
