Long-chain alkyl esters of O,O-dialkyl dithiophosphoric and thionophosphoric acids prepared on the basis of red phosphorus, elemental sulfur, alcohols, and industrial fractions of higher monoolefins

Mixtures of long chain S-alkyl O,O-dialkyl dithiophosphates, and O-alkyl O,O-dialkyl thionophosphates were obtained by the reaction of red phosphorus with elemental sulfur, alcohols, and industrial fractions of C16-C18 and C20-C26 of higher olefins in the presence of Lewis acid catalysts. The products obtained possess high anticorrosion activities toward mild steel.

Process for reacting alcohols and/or phenols with phosphorus pentasulfide

The invention relates to a process wherein an alcohol and/or phenol is reacted with phosphorus pentasulfide in the presence of a catalyst which is selected from (a) phosphonium salts of the general formula: STR1 (b) ammonium salts of the general formula: STR2 (c) phosphine oxides of the general formula: STR3 (d) phosphine sulfides of the general formula: STR4 (e) phosphinic acid derivatives of the general formula: STR5 In formulae I through V, the substituents R1, R2, R3 and R4 each stand for identical or different alkyl-, aryl-, alkaryl- or aralkyl- groups having from 1 to 22 carbon atoms. A stands for an inorganic or organic acid, and X and Y, respectively, stand for both oxygen and sulfur, and M stands for a monovalent metal or oxygen.
