Project Description

Synonym: Polyoxirane-2,3-Dicarboxylic Acid

CAS No. : 51274-37-4

Molecular Formula: HO(C4H2O5M2)n

Molecular weight: 400-1500

Structural Formula:

polyepoxysuccinic acid sodium


Polyepoxysuccinic Acid (Sodium Salt) is a multivariate scale and corrosion inhibitor with non-phosphor and non-nitrogen, it has good scale inhibition and dispersion for calcium carbonate, calcium sulfate, calcium fluoride, and silica scale, with effects better than that of ordinary organophosphines. When built with organophosphates, the synergism effects are obvious.

Polyepoxysuccinic Acid (Sodium Salt) has good biodegradation properties, it can be widely used in circulating cool water system in the situation of high alkaline, high hardness, and high pH value. It can be operated under high concentration index. Polyepoxysuccinic Acid (Sodium Salt) has good synergism with chlorine and other water treatment chemicals.
