| titleOfInvention | Methods for improved production of vitamins d2 and d3 |
| abstract | It is an object of the present invention to provide methods for producing vitamin D that gives improved yields and reduced side product contamination. In various aspects, these methods provide for production of vitamin-D 2 using ergosterol as provitamin D 2 or a dihydroxy derivative thereof as a starting material, or production of vitamin-D 3 using 7-dehydrocholesterol as provitamin D 3 or a dihydroxy derivative thereof as the starting material. The methods described herein comprise irradiating the starting material in a solution including an organic or inorganic base with light in the wavelength range 245-360 nanometers (nm) to obtain a product containing pre-vitamin-D 2 or pre-vitamin-D 3 , and heating the product to convert the resulting pre-vitamin-D 2 or pre-vitamin-D 3 to vitamin D 2 or vitamin D 3 . In various embodiments, these methods further comprise recovering vitamin D 2 or vitamin D 3 from this reaction as a purified product. |
