Chemical Properties

WHITE AMORPHOUS POWDER

Definition

ChEBI: An organic sodium salt that is the disodium salt of maleic acid.

General Description

Sodium maleate dibasic is the disodium salt of maleic acid. On reduction in the presence of Raney nickel at 100°C and 2500psi, followed by acidification, it affords succinic acid.1

Check Digit Verification of cas no

The CAS Registry Mumber 371-47-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,7 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 371-47:
(5*3)+(4*7)+(3*1)+(2*4)+(1*7)=61
61 % 10 = 1
So 371-47-1 is a valid CAS Registry Number.

Study of corrosion and scale inhibition of polyepoxysuccinic acid derivative

Liu, Xinhua,Wang, Wenjing,Tong, Xinjia,Ding, Yunfei,Zhao, Xinqiang,Su, Hong

, p. 7716 - 7720 (2015/02/02)

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.
