Uses

Used in Food Industry:
Disodium epoxysuccinate is used as a food additive for improving the texture, appearance, and shelf life of processed foods. It facilitates the blending of ingredients that would not normally mix, such as oil and water, ensuring a uniform and stable product. Its safety for consumption has been recognized by regulatory agencies like the FDA, making it a widely accepted ingredient in the food industry. However, individuals with sensitivities to disodium epoxysuccinate should be mindful of its presence in food products and check labels to avoid potential allergic reactions.

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.

Method for production of epoxy compound and hydroxy iminodisuccinic acid

The epoxidation is carried out in a reaction system made of metal under conditions such that the inner surface area (S) of the reaction system exposed to the gaseous-phase part thereof and the amount of the reaction solution (V) in the reaction system satisfy the formula: 02 /m3). The epoxidation, otherwise, is carried out in a reaction vessel such that at least the inner surface thereof exposed to the gaseous-phase part thereof has been inactivated or in a reaction vessel such that at least the inner surface thereof exposed to the gaseous-phase part thereof has been inactivated. A hydroxy iminodisuccinic acid is produced by causing the epoxysuccinic acid which has been obtained as described above to react with L-aspartic acid. By this reaction, an epoxy compound can be produced with a high yield without inducing coloration by epoxidizing a corresponding ethylenic compound with hydrogen peroxide. By using the epoxysuccinic acid obtained as described above, hydroxy iminodisuccinic acid of high quality can be produced without inducing coloration.

Lignin adducts

Disclosed herein are lignin adducts of the formula SPC1 Wherein X is an alkali metal cation, such as sodium, potassium and lithium. These lignin adducts are made by reacting an alkali lignin or sulfonated lignin with up to 10 moles of a salt of epoxysuccinate at a temperature of from 50°C. to 150°C. The lignodicarboxylic acid and its salts are useful as a dispersant and metal complexing agent.
