Abstract

Inventia se refera la derivati de dihidrocarbil fosfonati de amoniu, utilizabili ca aditivi antiuzura pentru lubrifianti, constituiti din dihidrocarbil, fosfonati de dialchilamoniu sau de alchilfenilamoniu, avînd formula generala: (vezi formula) în care R reprezinta alchil cu 1...10 atomi de carbon, R' reprezinta alchil cu 1...14 atomi de carbon, si R'' reprezinta alchil cu 1...14 atomi de carbon sau fenil. Procedeul de preparare a derivatilor conform inventiei foloseste ca reactanti dialchilfosfitii avînd 1...10 atomi de carbon în radicalul alchil si dialchilamine sau alchilfenilamine avînd 1...14 atomi de carbon în radicalul alchil, reactantii se supun reactiei, prin încalzirea timp de 3...10h, la temperaturi cuprinse în intervalul 50...150 degree C, reactantii nereactionati fiind îndepartati prin distilare la presiune de 2...mm Hg si la temperaturi cuprinse în intervalul 100...150 degree C.
