GRAPHICAL ABSTRACT

ABSTRACT

Reaction of red phosphorus with elemental sulfur, alcohols and amines results in formation of ammonium salts of O,O'-dialkyl dithiophosphoric acids. Microwave irradiation accelerates the reaction studied. Triethylammonium salt of O,O'-diisooctyl dithiophosphoric acid possesses high anticorrosion activity towards mild steel.
