    Product Overview:

    Vitamin B5 Powder is one of the B vitamins, which is one of the nutrients necessary for normal biological growth. Calcium pantothenate exists in three forms due to chiral carbon atoms: DL-body (mixed), D-body (dextrose) and L-body (levulose), only D-calcium pantothenate is biologically active, with the appearance of white or yellowish needle-like crystals or powder, melting point of 195 to 196 ° C (decomposition), soluble in water, methanol, glycerol, slightly soluble in ethanol and acetone, with hygroscopicity and a slight sweetness, but turned slightly bitter. As far as chemical stability is concerned, it is most stable in aqueous solution existing between pH 5 and 7, more stable in air and sunlight, and less stable in acid and alkali.

    Vitamin B5 Powder Usage and Synthesis.

    Pantothenic acid is the precursor of coenzyme A. It is an essential substance for a variety of metabolic processes (including carbohydrates, proteins, and lipids), and can participate in the synthesis of steroids, porphyrins, acetylcholine, and other substances, as well as maintain normal epithelial functions

    Calcium D-Pantothenate can be used as a nutritional supplement. Except for special nutritional foods, the amount used must be less than 1% (in terms of calcium) (Japanese standard). When fortifying milk powder, it is 10mg/100g. 0.02% is added to shochu and whisky to enhance the flavour.

    Adding 0.02% to honey prevents crystallisation in winter. Buffers the bitter taste of caffeine and saccharin.

    Vitamin B5 Powder

    Uses and functions of Vitamin B5.

    Feed additive, food additive, nutritional supplement. Enhances the flavour of shochu whisky and prevents honey from crystallising in winter

    This product is a vitamin analogue and is a component of coenzyme A. Among the mixed spins of calcium pantothenate, only the dextrose has vitaminic activity and participates in the metabolism of proteins, fats and sugars in the body.

    It is used for vitamin B deficiency and peripheral neuritis, as well as for colic after surgery. In combination with vitamin C, it is used to treat disseminated lupus erythematosus.

    Lack of calcium pantothenate in the human body has the following symptoms:

    (1) Growth cessation, weight loss, and sudden death.

    (2) Skin and hair disorders.

    (3) Nervous system disorder.

    (4) Disorders of digestive organs and liver dysfunction.

    (5) Influence on antibody formation.

    (6) Para-kidney disorders. The human body needs about 5mg of Calcium Pantothenate (as pantothenic acid) per day.Calcium Pantothenate is used as a nutritional supplement for food processing. The amount of calcium pantothenate used must be less than 1% (in terms of calcium), except for special nutritional foods (Japan).

    When fortifying milk powder, it is 10mg/100g. 0.02% is added to shochu and whisky to enhance the flavour. Adding 0.02% to honey prevents crystallisation in winter. Buffers the bitter taste of caffeine and saccharin.

    Vitamin B5 Raw

    Preparation of Vitamin B5.

    Calcium D-pantothenate can be produced by the aldol condensation of isobutyraldehyde with formaldehyde in the presence of potassium carbonate, followed by cyanidation and lactonisation to dl-pantolactone, which is then reacted with calcium aminopropionate.

    Vitamin B5 Raw Powder

    Poduction Method of Bulk Vitamin B5 Powder.

    Formaldehyde and anhydrous potassium carbonate were put into the reaction pot, isobutyraldehyde was added dropwise at 14-20 ℃, and the reaction was kept warm and stirred for 3h after addition; then it was left at 14-18 ℃ for 0.5h to obtain the upper layer of 2,2-dimethyl-3-hydroxypropanal as an oil.

    Dissolve 2,2-dimethyl-3-hydroxypropionaldehyde in 4 times of water, sodium cyanide in 6 times of water, calcium chloride in 2 times of water, and sequentially add the above solutions to the reaction pot; add 50% sulfuric acid solution under stirring, and react for 6h at 60~65℃, and then raise the temperature to 80~85℃ and react for 3h; concentrate under reduced pressure until thick, and add 95% of ethanol to make the inorganic salts precipitated and filtered off; the filtrate After recovering ethanol by distillation under reduced pressure, 130~145℃(1.33~2.39kPa) fraction was collected, i.e. γ-butyrolactone.

    Sequentially, β-aminopropionic acid, 5/6 of methanol and lime were added to the reactor, heated to 40 ℃ and stirred to react for 2h; the reaction solution was left to stand and then the upper layer of clear water was filtered, and the solid residue in the pot was washed with 1/6 of methanol and then pressed and filtered; the filtrate was placed in another reaction pot, and γ-butyrolactone was added and stirred to dissolve, and left to react for 40h to generate calcium pantothenate at room temperature.

    Add water and stir to cool to O ~ -5 ℃, and add the crystal seed stirring crystallisation 24h, filtered to get calcium pantothenate. Put 2/3 of the amount of calcium racemic pantothenate and calcium levulinate into the reaction pot, add methanol and water heated to 40 ° C and stir to dissolve, and filtered while hot, filtrate cooled to 15 ° C, add a small amount of calcium levulinate crystal seed, breeding crystals for 2h; when the specific optical degree of +6 ° ~ +8 °, separated from the crystals, and a small amount of methanol washed to get the levulinate calcium pantothenate (still used in splitting); the remaining 1/3 of the calcium racemic pantothenate stirring and dissolved In the filtrate at 35 ~ 40 ℃, filtered and cooled to 15 ℃, add a small amount of calcium dextro-pantothenate crystals, breeding crystals for 2h; when the specific optical degree of -0.6 ° ~ -0.8. Separate the crystals, and a small amount of methanol washed, vacuum-dried to obtain the dextro-calcium pantothenate
