Abstract
A process for the preparation of a composition comprising amine-containing phosphate glycerides including: phosphorylating a solution which comprises mixed glycerides that contain fatty acid portions and an amine under conditions which are substantially water-free and under which said phosphorous pentoxide reacts with reactive constituents in said solution to form said amine-containing phosphate glycerides and a lubricating composition comprising a lubricant, the aforesaid composition in an amount which improves the properties of the lubricating composition, and optionally one or more other constituents which improve the properties of the lubricating composition.
Claims27
A process for the preparation of a composition comprising amine-containing phosphate glycerides including:
- (a) preparing a solution which comprises mixed glycerides which contain fatty acid portions and an amine (hereafter “Solution A”);
- (b) preparing a reactive solution (hereafter “Solution B”) which comprises phosphorous pentoxide and Solution A, and (c) phosphorylating under conditions which are substantially water-free said phosphorous pentoxide with reactive constituents in Solution A to form said amine-containing phosphate glycerides.
A process for the preparation of a composition comprising amine-containing phosphate glycerides including:
- (i) providing a solution which comprises mixed glycerides which contain fatty acid portions and an amine (hereafter “Solution A”);
- (ii) providing a reactive solution (hereafter “Solution B”) which comprises phosphorous pentoxide and Solution A;
- (iii) combining Solution (A) and Solution (B);
- and (iv) subjecting the combined solutions to phosphorylating conditions which are substantially water-free and under which said phosphorous pentoxide reacts with reactive constituents in Solution A to form said amine-containing phosphate glycerides.
