chemical properties | No smell, taste sour. The light gradually blackening. Under dry condition, the air is fairly stable. But in solution and in the presence of air rapid deterioration. Melt and decompose at 164 ~ 172. This product is a heterogeneous body of ascorbic acid, similar to ascorbic acid, but the physiological activity of ascorbic acid (only about 1/20). The oxidation resistance is better than ascorbic acid, and the price is lower, but the heat resistance is poor. With strong reduction, the case of light is slowly colored and decomposed. Heavy metal ions can promote their decomposition. Very soluble in water (40g/100m1). Soluble in ethanol (5g/100ml). Difficult to dissolve in glycerin. Insoluble in ether and benzene. Specific rotation:-17.25°(c=10,H2O25°C),Refractive index:-17.5°(C=10,H2O),Water solubility:1g/10mL |
