Abstract:

Polyepoxysulfosuccinic acid has been prepared by using the sulfonation, epoxidation and polymerization procedure of maleic anhydride. -SO₃H group is introduced to the synthesized molecule. The polyepoxysulfosuccinic acid is characterized by IR and 1H, 13C NMR. Through the scale inhibition test, it has been found that the product has better performance of calcium carbonate and calcium phosphate scale inhibition than usual.

Key words: maleic anhydride, polyepoxysulfosuccinic acid, scale inhibition
