Натрия сукцинат

Химические свойства

Disodium succinate, also known as sodium succinate, white crystalline particle, odorless, not deliquescent in the air; soluble in water, and insoluble in organic solvents. Aqueous solution has a shellfish fresh flavor and no acidic taste. It can be used as a food flavoring agent, acidifier, or buffering agent.

Использование

Succinic acid disodium salt is used to prepare buffer solution for the quantitative analysis of auxins.
It can be also used:
    To study the effect of liquid phase on the basic properties of α-tricalcuim phosphate (α-TCP) based cement, BIOPEX.
    In the synthesis of cadmium sulfide (CdS) nanoparticles using thiourea as a source for sulfide.

Определение

ChEBI: Sodium succinate (anhydrous) is a sodium salt that is the disodium salt of succinic acid. The hexahydrate form is used as an ingredient of topical preparations for the treatment of cataract. It contains a succinate(2-).

Подготовка

Disodium succinate is produced by neutralizing succinic acid with sodium hydroxide. The anhydrous material is then dried at 120°C in hot air and pulverized to obtain.

Общее описание

Disodium succinate is used in the food industry as an acidity regulator and flavor enhancer.

Методы очистки

Crystallise it twice from water (1.2mL/g) and dry it at 125o. It has been freed from other metal ions by passage of a 0.1M solution through a column of Dowex resin A-1 (Na form). It is hygroscopic. [Beilstein 2 H 606, 2 IV 1908.]
