Chemische Eigenschaften

white semi-transparent crystals

Verwenden

Potassium sodium tartrate tetrahydrate has been used in the preparation of Lowry reagent for the determination of microsomal protein concentration in rat hepatic microsomes by Lowry method. It may be used as a constituent to prepare DNS (3,5- dinitrosalicylic acid) reagent and Fehling′s solution B, which are used in the determination of reducing sugar.

synthetische

Potassium sodium tartrate tetrahydrate is obtained by the follow steps:The starting material is tartar with a minimum tartaric acid content 68 %. This is first dissolved in water or in the mother liquor of a previous batch. It is then basified with hot saturated sodium hydroxide solution to pH 8, decolorized with activated charcoal, and chemically purified before being filtered. The filtrate is evaporated to 42 °Bé at 100 °C, and passed to granulators in which Seignette's salt crystallizes on slow cooling. The salt is separated from the mother liquor by centrifugation, accompanied by washing of the granules.

Allgemeine Beschreibung

Potassium sodium tartrate tetrahydrate is a ferroelectric crystal with a high piezoelectric effect and electromechanical coupling coefficient.

l?uterung methode

Recrystallise it from distilled water (solubility: 0.4mL/g at 100o, 0.7mL/g at 14o). [Beilstein 3 IV 1223.]
