Erythorbic Acid

Description:The Erythorbic Acid is the stereo isomer of Vitamin C, so its chemical character is same to the Vitamin C. The Erythorbic Acid is white to light yellow white crystal or crystal powder, odorless, has sourness, the melting point is 166~172? and decompounding, it will get gradually into black when meeting light. In dry state, it is rather stable in the air, but in the solution, when exposed to the air, it will quickly metamorphose, hardly have the physiology activity actions of the ascorbic acid, the antioxidation property is better than the ascorbic acid, but the heatdurability is poor, the reductibility is strong, the heavy metal ion can speed its decompounding. The Erythorbic Acid is easily dissolved in water, the dissolution value being 40g/100ml at normal temperature, hardly dissolved in glycerin, not dissolved in ethanol and benzene, its 1% water solution PH value is 2.8.
