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: ##STR1## 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.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
93 words
The product obtained by the steps consisting essentially of esterifying phosphorus pentoxide with at least one fatty acid alcohol having 10 to 20 carbon atoms and at least one carbon-carbon double bond to form a mixture of phosphoric esters, chlorinating said esters by addition of chlorine to the carbon-carbon double bond in the molecules of said esters obtained from the esterifying step, and salifying the thus chlorinated esters obtained at the end of the chlorinating step, with at least one base selected from the group consisting of an alkali, an amine and ammonia.
Claim 2
Dependent Claim
93 words
The product obtained by the steps consisting essentially of esterifying phosphorus pentoxide with at least one fatty acid alcohol having 10 to 20 carbon atoms and at least one carbon-carbon double bond to form a mixture of phosphoric esters, chlorinating said esters by addition of chlorine to the carbon-carbon double bond in the molecules of said esters obtained from the esterifying step, and salifying the thus chlorinated esters obtained at the end of the chlorinating step, with at least one base selected from the group consisting of an alkali, an amine and ammonia.
Claim 3
Dependent Claim
13 words
The product of claim 1, wherein the fatty acid alcohol is ricinoleic acid.
Claim 4
Dependent Claim
22 words
The product of claim 1, wherein said base is selected from the group consisting of sodium hydroxide, potassium hydroxide, lithia, and ammonia.
Claim 5
Dependent Claim
18 words
