PROCESS FOR PRODUCING AMINE OR AMIDE DERIVATIVES OF PHOSPHORIC AND SULFONIC ACIDS
For the prepn. of amine and amide derivs. of phosphoric and sulphonic acids, aq. solns. of alkali metal sulphonates of 300-700 average mol. wt. are treated in solvents contg. media with amines; conveniently with mono, di or tri-ethanol-amine, in the presence of fatty-alcohol-phosphoric-acid-monoeste...

| description | For the prepn. of amine and amide derivs. of phosphoric and sulphonic acids, aq. solns. of alkali metal sulphonates of 300-700 average mol. wt. are treated in solvents contg. media with amines; conveniently with mono, di or tri-ethanol-amine, in the presence of fatty-alcohol-phosphoric-acid-monoesters, at 60-80 deg.C. This is followed by the addn. of phosphoric acid to the reaction mixt. Sulphonic-acid-amide is produced when the reaction mixt. contg. a compelx salt mixt. is allowed to stand for 5-7 hours at 160 deg.C. Water formed during the reaction and any solvent present, as in this case, is removed by distillation. - Startup material sodium-sulphonates are by-products of purification of mineral oil derivs. by sulphuric acid or oleum. Convenient solvents are mineral oil fractions and macro and micro-crystalline paraffin waxes obtd. during petroleum refining. |
