Synthesis and its scale inhibition effect of green scale inhibitor polyepoxysuccinic acid
A green scale inhibitor polyepoxysuccinic acid(PESA) was synthesized from maleic anhydride in one step, and was characterized with IR and ~ 13 C NMR.The effects of PESA on CaCO_3 scale diameter and scale shape were investigated by size distribution measurement and SEM respectively.The dynamics of scaling process was studied, and the mechanism of scale inhibition was discussed.The results showed that PESA had high performance of scale inhibition on both dispersion and lattice distortion of CaCO_3.
