Utilization of orthophosphoric esters for the production of aqueous fluids for working metals

摘要

An aqueous composition for the working of metals comprising in solution in water at least one salt of an orthophosphoric ester of the formula: <IMAGE> 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.
