METHOD FOR INHIBITING CORROSION OF METALS USING POLYTARTARIC ACIDS

摘要

A method for inhibiting corrosion of metals in contact with an aqueous solution comprising adding to the system a corrosion inhibiting amount of one or more polytartaric acid compounds having the generalized formula: <IMG> wherein each R is independently selected from the group consisting of H and C1 to C4 alkyl, n is less than 4 and the average molecular weight of the mixture corresponds to an average n in the range 1.2 to 3.
