| titleOfInvention | METHOD FOR PRODUCING DERIVATIVES OF ASCORBIC ACID. |
| abstract | The invention relates to a method for preparing ascorbyl phosphates, in particular phosphates of formula (I), where Mk + represents a cation, k + the valence and m the equivalence, the product k.m being equal to 3, by phosphorylation of ascorbic acid. k is 1 to 3, in particular 1 or 2. The method is defined as follows: it is used as a phosphorylation reagent for preformed sodium (or potassium) dichlorophosphate, ascorbic acid is added to this reagent of preformed phosphorylation, in aqueous solution, particularly having a pH of between approximately 11.0 and approximately 13.0, in the presence of a water soluble trialkylamine acting as a catalyst, and at temperatures of between approximately 10 ° C and approximately -8 ° C, the operation being carried out in particular at temperatures below 0 ° C, and the product obtained as the sodium (or potassium) salt of formula (I) is, if necessary, doubly decomposed and / or purified using an amine salt. |
