CAS: 25395-66-8
Molecular Formula: C24H42O7
L-ASCORBYLSTERATE - Names and Identifiers
L-ASCORBYLSTERATE - Physico-chemical Properties
| Molecular Formula | C24H42O7 |
| Molar Mass | 442.59 |
| Melting Point | 117°C |
| Storage Condition | 2-8℃ |
| Physical and Chemical Properties | A slightly glossy white crystalline powder with chemical properties. The melting point is about 116 ℃. It is basically stable in the dry state, and it is easy to oxidize in the moisture absorption state, which reduces the effectiveness of vitamin C. Insoluble in water, soluble in peanut oil (0.09%), cottonseed oil (0.05%). |
| Use | Uses nutritional supplements, antioxidants. Is a lipophilic substance with vitamin C potency. In food can strengthen vitamin C and prevent oxidation. Can be used for fat and fat food, such as cream, cheese, milk powder, condensed milk, artificial cream, animal and vegetable oil, ham, sausage, chocolate, gum, hard candy and so on. |

L-ASCORBYLSTERATE - Uses and synthesis methods
identification test
solubility insoluble in water, soluble in ethanol (OT-42).
melting point is about 116 ℃, measured by conventional method.
its ethanol solution can fade 2, 6-dichloroindophenol test solution (TS-84).
content analysis
take 0.800g of sample, add it to a mixed solution consisting of 50ml of carbon dioxide-removed water, 50ml of chloroform and 25ml of dilute sulfuric acid test solution (TS-241), add several drops of starch test solution (TS-235), and immediately titrate with 0.1mol/L iodine solution under continuous agitation to the end point. 0.1mol/L iodine solution per mI is equivalent to 22.13mg of stearoyl ascorbate.
Toxicity
ADI 0~1.25 mg/kg(FAO/WHO,2001).
LD50 25070mg/kg (mice, oral).
use limited
FAO/WHO,1984: edible oil 500 mg/kg; Margarine (based on fat content), canola oil, coconut oil, palm oil, palm kernel oil, grape seed oil, Brazilian palm oil, cooked lard, refined lard, tallow, suet, soybean oil, peanut oil, cottonseed oil, rapeseed oil, corn oil, sesame oil, safflower seed oil, mustard oil, etc. are all 200 mg/kg.
USDA(9CFR & sect;318.7,2000): Margarine 0.02%.
production method
dissolve stearic acid of vitamin c in 95% acid and leave for 20h. Add crushed ice to precipitate stearoyl ascorbate, then extract it with an organic solvent such as ether, and wash it with water until there is no acid reaction. Recover organic solvent to precipitate the product, then recrystallize with petroleum ether, ether and other organic solvents and then dry them in vacuum.
