摘要： Ascorbic acid 2-phosphate is prepared by reacting ascorbic acid or an ascorbic acid derivative with POCl.sub.3 in the presence of a tertiary amine in a suitable aqueous solvent at from -10.degree. to 25.degree. C. while maintaining a pH of about 8-13.5 with KOH during the entire phosphorylation reaction and then isolating the ascorbic acid 2-phosphate, by a process in which an aqueous solution of a magnesium compound is added to the reaction mixture obtained in the phosphorylation, without prior treatment with an ion exchanger, until the formation of crystalline KMg PO.sub.4 is complete, the KMgPO.sub.4 which is crystallized out is separated off, the resulting filtrate is evaporated down at a pH of from 6 to 11 and/or from 0.1 to 5 times the amount, based on the evaporated filtrate, of a lower primary alkanol or acetone is added and the stirred mixture is cooled until KCl has completely crystallized out, and the ascorbic acid phosphate is isolated in a conventional manner from the reaction solution obtained by separating off KCl and substantially freed from inorganic salts. It is particularly advantageous if the ascorbic acid 2-phosphate is isolated in the form of the novel potassium magnesium ascorbate 2-phosphate, which is also claimed.The process is particularly advantageous if the ascorbic acid derivative used is 5,6-isopropylideneascorbic acid which has been obtained by reacting ascorbic acid with acetone in the presence of oleum. The process is particularly important for the preparation of L-ascorbic acid 2-phosphate.
摘要翻译：抗坏血酸2-磷酸酯通过使抗坏血酸或抗坏血酸衍生物与POCl 3在叔胺存在下，在-10℃至25℃的合适的水性溶剂中反应制备，同时保持约8-13.5的pH，同时用 KOH，然后通过将镁化合物的水溶液加入到磷酸化中获得的反应混合物中而不用离子交换剂进行预处理的方法分离出抗坏血酸2-磷酸酯，直到形成结晶KMg PO4完成后，将结晶出来的KMgPO4分离出来，所得滤液按照蒸发滤液的6至11和/或0.1至5倍的pH蒸发掉，加入低级主链烷醇或丙酮，将搅拌的混合物冷却直至KCl完全结晶出来，并以常规方式从得到的反应溶液中分离抗坏血酸磷酸酯通过分离KCl并基本上从无机盐中除去。特别有利的是，抗坏血酸2-磷酸酯以新的抗坏血酸钾2-磷酸2-钾的形式被分离，这也是要求保护的。如果所使用的抗坏血酸衍生物是在发烟硫酸存在下使抗坏血酸与丙酮反应获得的5,6-异亚丙基抗坏血酸，该方法是特别有利的。该方法对于制备L-抗坏血酸2-磷酸酯尤为重要。

摘要： An improved process for preparing cyclic acetals of 3-formyl-2-butenyltriphenylphosphonium chloride by acetalization of 3-formyl-2-butenyl acetate with an aliphatic 1,3-diol, conversion of the resulting 4-acetoxy acetal into the corresponding 4-hydroxy acetal, Vilsmeier chlorination to give the corresponding 4-chloro acetal and subsequent reaction with triphenylphosphine entails carrying out the first 3 steps in an aliphatic or cycloaliphatic hydrocarbon or mixture of hydrocarbons with 6-8 carbons and the reaction with triphenylphosphine in an alkanol with 1-3 carbons and/or in aliphatic or cycloaliphatic hydrocarbon with 6-8 carbons or a corresponding mixture of hydrocarbons. The process is particularly advantageous when conversion of the 4-acetoxy acetal into the 4-hydroxy acetal is carried out with an aqueous alkali metal hydroxide solution in the presence of phase-transfer catalysts, and the first three, or all four, reaction stages are carried out in the same C.sub.6 -C.sub.8 -hydrocarbon.

摘要： Potassium magnesium L-ascorbate 2-phosphate is prepared from an aqueous solution of potassium L-ascorbate 2-phosphate which is highly contaminated with KCl, as is produced in the phosphorylation of 5,6-isopropylidene-L-ascorbic acid, by adding to the solution about 1 equivalent of magnesium ions per equivalent of L-ascorbate 2-phosphate, and subsequently removing the KCl by electrodialysis. The product of this process is a novel salt of L-ascorbic acid 2-phosphate and has very advantageous handling properties.
