Manufacturing Vitamin D3 by Photocatalytic Process
Vitamin D3 is the additives for the vitamin drugs and food. As a food additive, it is widely used in calcium health care products and biscuits, beverages,and other foods. As feed additives, it can significantly increase the egg production rate; increasing meat, eggs, milk nutritional value.
Molecular formula: C27H44O M.W: 384.64
(1) < name> Vitamin D3
(2) <synonym> 7-dehydro cholesterol,
(3) <Chemical name> 9.10- Cholesteric -5.7.10 (19) - triene -3 - alcohol
Product Specification:
Light yellow to brown particles
Content of 500,000 IU / g
More than 5% loss on drying
USE:
1.Added to feed for animals to prevent rickets,
2.Banlance the metabolism of calcium and phosphorus, especially the promotion of intestinal calcium and phosphorus absorption;
3.Controlled calcium and phosphorus storage in bone;
4.Improved calcium and phosphorus conversion rate in bone
5.Contributing to the growth of animal bones.
Dosage:
Vitamin D3 requirements depend on calcium and phosphorus additional information. If Calcium and phosphorus in the proportion of inadequate or inappropriate, it will increase the requirement of vitamin D3. According to animal species and production performance, feed per kilogram of vitamin D3 in the demand is 1000-5000 units.
Process Discription:
Cholesterol is used as the starting material of vitamin D3,which is the total synthesis of biological products. A variety of organic solvents are used in Production processes, which decided to request the product of high technology, low yield, equipment requirements and specificity of the technical operation of a certain request.
Technical data:
7-dehydro cholesterol yield: 40.40-53 .43%;
Vitamin D3 total yield: 20%
