ASCORBIC ACID 2-PHOSPHATE MAGNESIUM ESTER - Reference Information

Use Magnesium vitamin C phosphate is a vitamin C derivative, which derivates the 2-position hydroxyl group into phosphate ester to improve the stability of vitamin C. The formed derivative can regenerate vitamin C after being hydrolyzed by phosphatase, which is widely present in the body, so it has become the main component of feed additives, food fortifier and advanced cosmetics whitening, is a valuable fine chemical.
as an antioxidant, GB 2760-1996 stipulates that it can be used in oil-containing foods, edible oils, hydrogenated vegetable oils and instant noodles. the maximum usage amount is 0.2 g/kg, and the maximum usage amount in infant formula is 0.01 g/kg (based on ascorbic acid in oil). In addition, it can also be used as a food nutrition enhancer.
used as feed additive
1. inhibit tyrosinase activity, reduce melanin, with freckle whitening effect. 2. After entering the body, oxygen free radicals can be eliminated, thus having anti-wrinkle and anti-aging functions. 3. Synergistic effect with vitamin E.
chemical properties white (slightly yellowish) powder, tasteless and odorless. Soluble in dilute acid, soluble in water, insoluble in organic solvents such as ethanol, ether and chloroform. Resistant to light and heat, stable in the air and hygroscopic. The oral LD50 of mice is greater than 21.5 g/kg.
production method add 10g(0.057 mo1)L-ascorbic acid (AA) and 250mL acetone to a 500mL flask, then add AA amount of 5.2% stannous chloride (SnCl2 · 2H2O) catalyst, 2 zeolites, a Soxhlet extractor on the flask, and 20g of anhydrous sodium sulfate (wrapped with dry filter paper), reflux at 80 ℃ for 1.5h, and stop after AA reaction. Filtration, atmospheric distillation of the filtrate to recover acetone, after most of the acetone is evaporated, a small amount of n-hexane is added, cooling and suction filtration, the product is washed with a small amount of 4:7 (volume ratio) acetone n-hexane, and the white product 5,6-O-isopropylidene-L-ascorbic acid (IAA) is 11.6g, the yield is 94.3%, and the melting point is 217~219 ℃. Water as solvent! Add 2.2mol/I. Pyridine and 10mol/I. Potassium hydroxide (Ph = 12~12.5) was reacted in IAA at 0~10 ℃ by dropping a slight excess of phosphorus oxychloride. After being refined by cation exchange resin, it was neutralized with magnesium oxide to obtain the product with a yield of more than 70%.
