Abstract
Abstract An aqueous composition for the working of metals comprising in solution in water at least one salt of an orthophosphoric ester of the formula: ##EQU1## in which R is a hydrocarbon group containing between 10 and 20 carbon atoms and at least two atoms of chlorine, R' is hydrogen or a hydrocarbon group, identical or not to R, whose carbon chain contains between 10 and 20 carbon atoms and at least two atoms of chlorine.

Claim 2
Dependent Claim
11 words
A water soluble salt selected from the group consisting of ##EQU2##2.
Claim 3
Dependent Claim
79 words
A process for producing a salt of a chlorated orthophosphoric ester comprising esterifying at least one of phosphorus pentoxide or orthophosphoric acid or phosphorus oxichloride by oleic alcohol, chlorating by addition to the carbon chain in the molecules of the phosphoric ester obtained from the esterifying step, and salifying the thus chlorated phosphoric ester obtained at the end of the chlorating step, by at least one base selected from the group consisting of an alkaline, an amine and ammonia.
Claim 4
Dependent Claim
