O,O-dialkyldithiophosphoric acids in the reactions with nonactivated α-olefins

Reactions of O,O-dialkyl dithiophosphoric acids with hexadec-1-ene, octadec-1-ene, and also 2-methylpentadec-1-ene and 2-methylheptadec-1-ene as impurities in commercial samples of hexadec-1-ene and octadec-1-ene, and pure 2-methylpent-1-ene were studied in the presence of zinc chloride and ultrasound irradiation. © 2013 Copyright Taylor and Francis Group, LLC

Novel effectively carbonaceous and sulfurated hydrogen corrosion inhibitors on the basis of organosulfurphosphorus compounds

Novel ammonium salts of O,O-dialkyl dithiophosphoric acids were obtained by one-pot synthesis from white phosphorus, elemental sulfur, industrial alcohols or phenols, and amines. Long-chain S-alkyl O,O-dialkyldithiophosphonates were prepared by the reaction of red phosphorus with elemental sulfur, alcohols, and the cheap industrial fractions of C16-C18 and C 20-C26 of higher α-olefins in the presence of Lewis acid catalyst. The dithiophosphates obtained possess the high anticorrosion activities toward mild steel. © 2013 Copyright Taylor and Francis Group, LLC
