L-ascorbic acid-2-phosphoric acid potassium crystal and method for producing the same |
摘要 |
A high-purity L-ascorbic acid-2-phosphoric acid potassium crystal having excellent stability, and a method for simply producing the high-purity L-ascorbic acid-2-phosphoric acid potassium in a high yield by adding dropwise a solution containing L-ascorbic acid-2-phosphoric potassium to methanol or simultaneously mixing methanol and a solution containing L-ascorbic acid-2-phosphoric acid potassium. By the production method of the present invention, high-purity L-ascorbic acid-2-phosphoric acid potassium crystal having excellent stability can be simply produced in a high yield. The L-ascorbic acid-2-phosphoric acid potassium crystal obtained by the production method of the present invention is used for feedstuff, cosmetic materials, medical products, food additive and the like.
