A prep work technique of Ascorbyl Magnesium Phosphate, including the adhering to procedure actions:
( 1) Include 110Kg vitamin C, 8.8 Kg anhydrous calcium chloride, and 110Kg deionized water into a 500L response kettle at -10 ° C, stir for 2 hrs, and afterwards add 30% sodium hydroxide liquid remedy dropwise to adjust the pH. is 5, after that include 110Kg of salt trimetaphosphate, maintain the temperature level at 25 ° C, as well as react for 2 hours. The obtained reactant is calcium vitamin C ester;
( 2) Add vitamin C ester calcium into a 500L barrel cleaner to clean with water, and afterwards utilize sulfuric acid to adjust the pH to 1.5. The obtained reactant is vitamin C phosphate;
( 3) The vitamin C phosphate goes through nanofiltration membrane filtration via a rolled nanofiltration membrane layer filter. The temperature at the inlet of the rolled nanofiltration membrane filter is 120 ° C, and also the temperature at the electrical outlet of the rolled nanofiltration membrane filter is 30 ° C; The nanofiltration membrane layer has nano-scale pores, and also the molecular weight cutoff of the nanofiltration membrane layer is 500. The roll-type nanofiltration membrane layer filter has a high elimination price of inorganic salts, with an elimination rate of 90%;.
( 4) Add the filtrate obtained by filtering in step (3) right into a 500L reaction kettle, go through the weakly standard anion exchange material, as well as elute with 0.05 M hydrochloric acid and also 0.5 M hydrochloric acid in sequence. Gather the eluted component, and also the eluted component is stirred continuously. Usage magnesium oxide to change the pH to 7, and also the obtained catalyst is vitamin C magnesium phosphate;.
( 5) Filter magnesium vitamin C phosphate through a turned on carbon filter to remove the precipitate. The filtrate is concentrated under reduced stress at 30 ° C to one-fifth of the initial volume. Add ethanol with a volume of 3 times the concentrated filtrate and a web content of 95%, and after that spray it with Drying with a dryer, the drying temperature level is 140 ° C, and the drying time is thirty minutes, to acquire 79.85 KG of white magnesium vitamin C phosphate, with a material of 97.75%.
The manufacturing method of Ascorbyl Magnesium Phosphate. Ascorbyl Magnesium Phosphate is composed of vitamin C, salt trimetaphosphate, calcium hydroxide, and calcium chloride. It is identified because: 50% vitamin C, 30% salt trimetaphosphate, 20% Calcium hydroxide is included in the esterification pot for chain reaction and mixed extensively; after that a proper quantity of calcium chloride is included in produce vitamin C phosphate; an ideal amount of magnesium oxide is contributed to the created vitamin C phosphate, as well as it is improved as well as dried out, dried out, squashed, examined, and also packaged right into vitamin C magnesium phosphate products. In the certain application, esterification: place 70-80kg solid antacids right into the alkali-dissolving storage tank and start the stirrer for 10-15 mins to liquify, place 130-150kg vitamin c right into the esterification pot, mix and also liquify thoroughly for 10-20 mins, as well as include Slowly add alkali remedy into the response pot, regulate the reaction temperature at 20-35 ° C, as well as constantly evaluate the ph value. When the ph worth gets to 6-8, placed 90-120kg of salt trimetaphosphate into the pot and also remain to include alkali., when the pH worth reaches 11-13, quit adding antacids, maintain warm as well as mix for about 2 hours. Drying as well as granulating: Include the esterification material right into the centrifuge, and the filling volume is two-thirds of the centrifuge capacity. After drying out for 2 hrs, the product is discharged. The completely dry material released from the centrifuge is granulated and dried by the granule swing device. Drying out and crushing: Include 150kg-200kg of bits to the hopper each time. When drying the product, the inlet air temperature is controlled at 110-135 ° C. When the outlet air temperature level reaches 70-80 ° C, the product is released. Seclusion: Accurately weigh 20kg of each batch and also acidify with a proper quantity of anion material. After acidification, put it into a response storage tank consisting of 500L of soft water, and activate the mixer. After stirring for 2 hours, accurately determine 400L and also put it right into the reaction tank. Neutralization: Use soft water to prepare a 50% magnesium oxide liquid solution for later usage. Switch on stirring as well as slowly include the magnesium oxide aqueous solution right into the reaction container. Ultimately, readjust the pH value to between 8-9, as well as regulate the whole magnesium addition time to around 2 hrs. The material fluid and magnesium oxide fully react for regarding 5 hrs, then the magnesium slag is filteringed system, kept warm and also decolorized for 40 minutes, and also the carbon is drawn out, as well as the material liquid is sent out to the crystallization container for crystallization. Formation: Control the temperature in the crystallization tank at 50-60 ° C, begin adding alcohol slowly as well as equally, the alcohol enhancement process takes 1.5-2 hours, maintain the crystals warm for 2 hours, switch on the air conditioning water to cool off, when the temperature drops to 30-40 ° C When, begin centrifugal spin drying out. Refining: 40kg of each set of taken shape dry product is evaluated and pumped right into a dissolving storage tank with 400L of soft water. Mix and liquify completely for 24 hr. Pump the made clear fluid right into the crystallizing tank. Open up the steam shutoff and raise the temperature to 50-60 ° C. Add gradually. 80-120L alcohol, after information, essence the cleared up fluid, maintain it warm for 2 hrs, after that start cooling. When the temperature level goes down to 30-40 ° C, start centrifugal drying out, and also discharge the product for drying out. Drying, squashing, testing, as well as product packaging: Place equal quantities of refined semi-dry materials into drying bags, lay them flat, and put them in the drying out box. Open up the vacuum and heating shutoffs, regulate the drying temperature to 38-55 ° C, as well as the vacuum degree to 0.8 Mpa or above., completely dry for 20-24 hrs, crush and sieve the dried products, and afterwards package after passing the research laboratory assessment.
