Abstract

Trivalent phosphorus esters of formula: RxP(OR)1)3-x where X is 0, 1 or 2, R is an aliphatic, araliphatic or aromatic radical and R1 is an aliphatic, cycloaliphatic or araliphatic radical are prepared by reacting a phosphorus halide of formula: RxP Hal3-X with at least an equivalent amount of an alcohol in the presence of at least on equivalent amount of a secondary aliphatic amine, the amounts of alcohol and amine being based on the halogen content of the phosphorus halide. An inert solvent may be used. In a modification, the halide and amine are first reacted to form a phosphorus amide which is isolated and reacted with the alcohol, preferably at a temperature higher than the boiling point of the secondary amine liberated, said amine preferably having a lower boiling point than the alcohol and being distilled off. The amine halide formed in the one stage process or in the first stage of the two stage process may be extracted with water. Reaction temperatures of up to about 200 DEG C. are mentioned. Esters prepared in examples are trimethyl, triethyl and tri(2-ethylhexyl) phosphites, dimethyl methylphosphonite, diethyl ethylphosphonite, diethyl phenylphosphonite and methyl, diphenylphosphinite. Intermediate phosphorus amides prepared are phosphorous hexamethyltriamide, and methyl-, ethyl-, and phenyl-phosphorous tetramethyldiamides.
