D-Tartaric acid Usage and Synthesis.

Tartaric acid is widely used as an acidifier for beverages and other foods, a use similar to that of citric acid. Tartaric acid is used in combination with tannins as a mordant for acid dyes, and is also used in certain developing and fixing operations in the photographic industry, where its iron salts are photosensitizing and can therefore be used to make blueprints.

Tartaric acid can complex with a variety of metal ions, and can be used as a cleaning agent and polishing agent for metal surfaces. Potassium sodium tartrate (Rochelle salt) can be prepared Ferrin reagent, but also used in medicine as a laxative and diuretic, but also used as an intermediate of Simcorffin.

Its crystals have piezoelectric properties and can be used in the electronic industry. Mainly used in beverage, candy, bread, gelatin as acidifier, biochemical reagent, racemate splitter, pharmaceutical splitter.

Uses of D-Tartaric acid.

Used as pharmaceutical splitting agent, food additives, biochemical reagents, etc.. Uses: This product is widely used in food industry, such as as beer foaming agent, food souring agent, corrective agent, used in refreshing drinks, candy, fruit juice, salsa, cold dishes, baking powder and so on. This product conforms to the Japanese Food Additives Public Definition.

Tartaric acid can complex with a variety of metal ions, and can be used as a cleaning agent and polishing agent for metal surfaces. Potassium sodium tartrate (Rochelle's salt) can be formulated with Ferrin's reagent, and can also be used in medicine as a laxative and diuretic, and as an intermediate for Simcorffin. Its crystals have piezoelectric properties and can be used in the electronics industry.

Characteristic of D-Tartaric acid.

Three stereoisomers of tartaric acid exist: lithotrizoic acid, levotrizoic acid, and endo-racemic tartaric acid. Mixtures of equal amounts of the dextrorotatory and levorotatory forms, whose rotational properties cancel each other out, are called racemic tartaric acid. The internal racemate does not occur in nature and can be chemically synthesized. All types of tartaric acid are colorless crystals that are soluble in water.

Product Method of D-Tartaric acid.

Tartaric acid exists mainly in the form of potassium salts in the fruits of many plants, and also exists in small amounts in the free state.

Dextro-tartaric acid is commonly produced industrially by fermentation of glucose; the racemate can be produced by oxidation of transbutylene dioic acid with potassium permanganate; the endomorph can be produced by oxidation of cisbutylene dioic acid with potassium permanganate; and levotartaric acid can be obtained by splitting the racemate.

In the practical application field of tartaric acid, dextro-tartaric acid or its complex salts are mainly used. Tartar, a by-product of grape-making, is currently the main raw material for the practical production of tartaric acid, and the tartaric acid produced is all dextro-form.
