Study of corrosion and scale inhibition of polyepoxysuccinic acid derivative

Polyepoxysuccinic acid derivative was synthesized from L-cysteine and polyepoxysuccinic acid a condensation polymer formed by cyclization and polymerization with maleic anhydride. The structure of polyepoxysuccinic acid derivative was characterized by means of FTIR and 13C NMR. The scale inhibition and corrosion inhibition performances of polyepoxysuccinic acid derivative were studied. Scale inhibition and corrosion mechanisms were analyzed by means of SEM. The scale inhibition rate of polyepoxysuccinic acid derivative can reach 98.9 % under Ca2+ 400 mg L-1, HCO3- 800 mg L-1, polyepoxysuccinic acid derivative 8 mg L-1. Polyepoxysuccinic acid derivative is better than polyepoxysuccinic acid in corrosion inhibition performance and the corrosion inhibition rate can reach 65.14 % at 40 °C in dynamic experiment. SEM showed that the calcium carbonate crystal lattice was distorted completely from calcite to vaterite by using polyepoxysuccinic acid derivative. The surface of the test piece has dense protective adsorption film layer when it was immersed in solution with polyepoxysuccinic acid derivative.

Chemical process

There is disclosed herein improved processes for the preparation of ether carboxylates by reacting in an alkaline reaction medium the salts of maleic acid and a carboxylic or polycarboxylic acid having a reactive hydroxyl group on a non-carbonyl carbon atom in the presence of a calcium ion catalyst wherein unreacted acid salts are recovered from the reaction medium by lowering the pH of the reaction medium to a range of from about 4 to about 6. The precipitated salts are recycled to the synthesis reaction to prepare additional amounts of product.
