What is Magnesium Ascorbyl Phosphate?

The phosphorylation of vitamin C mainly has two methods: one is the phosphorylation of phosphorus oxychloride (as described in European Patents 388869 and 582924, U.S. Patent 4179445, Japanese Patent Publication Sho 60-69079, etc.), with vitamin C C is the raw material, the hydroxyl groups on the 5th and 6th carbons are protected before esterification, that is, vitamin C is first reacted with acetone to generate 5,6-oxo-isopropylidene-L-ascorbic acid (5,6 -0 — isopropylidene-L-ascorbic acid), then dissolved in pyridine solution, adjusted the pH value with KOH, added phosphorous oxychloride dropwise to react, evaporated the pyridine and removed the salt for many times, concentrated, and then exchanged with cation resin, collected and eluted liquid, add MgO for reaction, and finally complete the crystallization, filtration and drying of low-carbon alcohol. Its product is mainly L-ascorbic acid-2-monophosphate, and by-products are mainly L-ascorbic acid-3-phosphate and 2-pyrophosphate and two (ascorbic acid)-2,2′-diphosphate.

The reaction product requires a complicated process for purification, and it is not possible to dry all the reaction mixture by a simple method. The second method is to use phosphate to phosphorylate, such as the methods of U.S. Patent Nos. 4,647,672 and 5,110,950, and the main product obtained is L-ascorbic acid-2-polyphosphate. 2-triphosphate, but also contains a proportion of L-ascorbic acid-2-monophosphate.

The former can be degraded to monophosphate by excess base, the ratio of which depends on the stoichiometric ratio of the starting materials and the specific reaction conditions. The purification of L-ascorbic acid-2-monophosphate from the mixture is not easy either, and the residual inorganic salts in the product are often high. Although the method synthetic route is short, there are many by-products, product separation and purification are difficult, and the total product yield is low. The traditional synthesis process of Magnesium ascorbyl phosphate is complicated, with many impurities, and the use of organic solutions such as acetone causes damage to the environment.

Magnesium Ascorbyl Phosphate Uses

  1. Magnesium ascorbyl phosphate has come to be the primary element of feed additives, food fortifiers as well as progressed cosmetic whitening, and also is a beneficial great chemical.
  2. Magnesium ascorbyl phosphate On top of that, it can also be used as a food nourishment fortifier.
    Magnesium ascorbyl phosphate as feed additive.
  3. Magnesium ascorbyl phosphate1. Hinders tyrosinase activity, decreases melanin, and has freckle as well as bleaching effects. 2. After getting in the body, it can get rid of oxygen cost-free radicals, so it has anti-wrinkle as well as anti-aging features. 3. It has a synergistic result with vitamin E.

Summary of the Invention of Magnesium Ascorbyl Phosphate

The item of the present innovation is to get rid of the shortages existing in the prior art, give a kind of prep work method of Magnesium Ascorbyl Phosphate with basic technique, practical operation, low cost and also high yield, this technique does not make use of organic solvent in the preparation procedure, aftertreatment It is straightforward, does not trigger environmental pollution, as well as the ready item has high purity.

According to technical plan given by the innovation, a kind of preparation approach of Magnesium Ascorbyl Phosphate, is characterized because, consists of the complying with processing steps:

( 1) including vitamin C, anhydrous calcium chloride, deionized water according to the mass ratio of 1: (0.08 ~ 0.4): (1 ~ 5) temperature is in the activator of -10 ~ 20 DEG C, mixes 2 ~ For 3 hrs, include the sodium hydroxide liquid remedy with a focus of 30 ~ 70% dropwise, readjust the pH to 5 ~ 10.5, then add sodium trimetaphosphate with 1 ~ 2.5 times the quantity of vitamin C, keep the temperature level at 25 ~ 45 ° C, and respond 2 ~ 6 hrs, the obtained reactant is vitamin C ester calcium;

( 2) adding vitamin C ester calcium into the container cleaner to wash with water, and afterwards readjusting the pH with sulfuric acid to be 1.5 to 3.5, as well as the gotten reactant is vitamin C phosphate;

( 3) execute nanofiltration membrane purification with vitamin C phosphate via the roll kind nanofiltration membrane layer filter, the temperature level of the roll kind nanofiltration membrane filter inlet is 120 ~ 140 ℃, and the temperature level of the roll type nanofiltration membrane layer filter electrical outlet is 30 ~ 50 ℃; Nanofiltration membrane has nanometer pore dimension, the molecular weight cut-off of nanofiltration membrane layer is 500 ~ 1500, and also the roll type nanofiltration membrane filter has greater removal price to not natural salt, as well as removal rate is 90 ~ 98 %;

( 4) adding the filtrate acquired by the action (3) purification into the activator, through weakly standard anion exchange resin, eluting with 0.05 M hydrochloric acid and also 0.5 M ~ 1.5 M hydrochloric acid together, gathering the elution component, as well as the elution component is continuously Adjusting pH with magnesium oxide under mixing is 7 ~ 11, as well as the reactant that gets is vitamin C magnesium phosphate;

( 5) Magnesium Ascorbyl Phosphate is filtered to eliminate rainfall through gac filter, filtrate is concentrated to one-fifth of original volume at 30 DEG C under minimized pressure, adding quantity is that 3 ~ 6 times of focused filtrate content is 95% ethanol, then by Spray clothes dryer drying out, drying out temperature level is 140 ~ 160 ℃, and also drying out time is 30 ~ 40min, promptly obtains explained Magnesium Ascorbyl Phosphate completed product.

Compared with the previous art, the present development has the complying with benefits:
The phosphoric acid esterification response of today development is performed in an aqueous solvent, does not make use of an organic solvent, and also the whole process is straightforward, not only accelerates the phosphoric acid esterification response rate, reduces the response time, simplifies the operation treatment, yet also is eco secure; a new sort of nanofiltration membrane is used. process, the elimination efficiency of contaminations is high, and the pureness of the ended up Magnesium Ascorbyl Phosphate is greater than 95%, and the security is excellent.
