1. Vitamin B5 (d calcium pantothenate) introduction
D-Calcium pantothenate, also known as vitamin b5, CAS No. 13708-6, is an indispensable biological component in the process of biological growth. There are three forms of calcium pantothenate, D-calcium pantothenate, L-calcium pantothenate, and DL- calcium pantothenate, among which D-calcium pantothenate has biological activity.
After entering the human body, pantothenic acid and calcium are released, and pantothenic acid plays an important physiological role. Calcium pantothenate is widely used in feed, food, and medicine.
2. Raw Material of Vitamin B5 (d calcium pantothenate)
The preparation of d calcium pantothenate is complicated, and its two raw materials are DL- pantothenic acid lactone and β-aminopropionic acid. DL- pantothenic acid lactone is prepared from butyrolactone, hydrocyanic acid, and isobutyraldehyde. Acrylic cyanide is the main raw material of β-aminopropionic acid, and formaldehyde is the main auxiliary material for the production of β-aminopropionic acid.
From this point of view, the raw materials of vitamin b5 are all chemicals, and the price of raw materials accounts for about 60% of the production cost. The price of raw materials has an impact on the price of finished products.
3. How D-calcium pantothenate is produced
There are two main synthesis processes on the market. One is to synthesize DL-pantoic acid lactone and continue to react with β-alanine to synthesize DL-calcium pantothenate, and then split to obtain D-calcium pantothenate, as shown in figure 1. The other is to first split DL-pantoate lactone into D-pantoate lactone and then combine with β-alanine to prepare D-calcium pantothenate, as shown in figure 2.
The figure 1 manufacturing process is traditional and more popular among manufacturers both dosmetic and abroad. The operating principle is that DL-calcium pantothenate has bigger solubility than d-calcium pantothenate and l-calcium pantothenate. Then L-calcium pantothenate was racemized by alkali-catalyzed racemization and repeatedly resolved and converted to D-calcium pantothenate. The good point is that it has good technological maturity. The bad one is that it only could produce d-calcium pantothenate, can’t produce its derivatives, like panthenol.
The figure 2 process is to change DL-pantoate lactone into D-pantoate lactone. There are two methods in the separation process, one is chemical separation, which has high cost and high pollution. The other is the use of biological enzymes, which has the advantages of simple operation, low cost, and environment-friendly.
