FIELD: chemistry of organophosphorus compounds.
SUBSTANCE: invention relates to synthesis of anticorrosive and biologically active chemical compounds, in particular, phosphorus-containing condensation products of thiourea and formaldehyde. The proposed new chemical compound - N,N-bis-(phosphatomethylene)-N'-hydroxymethylene-N'-(phosphonitomethylene)-thiourea shows the following chemical formula: 
and provides reducing the corrosion rate and enhancing the protective effect of steel against corrosion and biological overgrowing. Proposed compound can be used for protection of equipment of water-circulating reusable systems against corrosion and biological overgrowing, and as a component of water-mixable lubricant-cooling liquid also.
EFFECT: improved and valuable properties of inhibitor.
