Research on hydroxyethyl ammonium O,O′-diphenyl dithiophosphate: Synthesis, characterization, surface activity and corrosion inhibition performance

Hydroxyethyl ammonium O,O′-diphenyl dithiophosphate (HADD) acting as a surfactant and corrosion inhibitor was successfully synthesized and characterized by FT-IR, 1H NMR and single crystal X-ray diffraction. Meanwhile, the inhibition effect of HADD on Q235 steel (Q235s) corrosion in H2SO4 solution was studied by weight loss and potentiodynamic polarization measurements. HADD turned out to be an effective corrosion inhibitor and the inhibition efficiency increased with HADD concentration increasing, and significantly decreased with increasing both temperature and H2SO4 concentration. Potentiodynamic polarization measurements indicated that HADD was a mixed-type inhibitor.

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.
