摘要：

New ammonium salts of O,O'-dialkyldithiophosphoric acids have been obtained based by the reaction of white phosphorus (P(4))-alcohol-amine-elemental sulfur. The reaction is characterized by full conversion of white phosphorus and is not accompanied by the release of hydrogen sulfide. It has been established that all studied compounds are highly efficient inhibitors of CO(2)-mediated corrosion of mild steel active at concentrations of 0.25-5 mg(.)L(-1).
