摘要
以维生素C和CaCO3为原料 ,合成Vc -Ca。最佳工艺条件为 :反应温度 6 0℃ ,反应时间2h ,Vc∶Vc .Ca =1∶1.0 5。实验结果表明 ,在此工艺条件下 ,产品收率可达到 97.33% ,含量为 98.2 4 %。
Vitamine C calcium was synthesized by using vitamine C and calcium carbonate as raw materials. The most suitable industrial conditions: reaction temperature was 60 ℃, reaction time was two hours, the ratio of vitamine C to calcium carbonate was 1∶1.05. The results of experiments showed: under this conditions, the yield was 97.33 %, the content of produet was 98.24 %.
