| Abstract: | Taking the ascorbic acid as raw material,through single factor and orthogonal experiment in the open systems,various factors is disscussed in aqueous solution of ascorbic acid directly acylation reaction of polyphosphate,the results show that the optimum reaction conditions: the ascorbic acid content is 95%~100%,the sodium trimetaphosphat content is 70%,ascorbic acid and sodium trimetaphosphatin in the mass ratio of 1∶1,ascorbic acid and calcium chloride in the molar ratio of 1∶0.075,the reaction temperature is 40~50 ℃,the reaction solution pH of 10,the content of ascorbyl polyphosphate is up to 36.87% and the yield is up to 96.84%. |
