KPO_3-MoO_3体系平衡固相的研究

Preparation of Sodium Fructose 1,6 Diphosphate

本文对ＫＰＯ３－ＭｏＯ３体系平衡固相作了较详细的研究．用Ｘ－射线衍射证明在５０ｍｏｌ％ＫＰＯ３－５０ｍｏｌ％ＭｏＯ３处及７５ｍｏｌ％ＫＰＯ３－２５ｍｏｌ％ＭｏＯ３处有两化合物存在．３１Ｐ核磁共振进一步证实它们的化学式为ＭｏＯ３·ＫＰＯ３和３ＫＰＯ３·ＭｏＯ３的可靠性。

The crude sodium fructose 1,6 disphosphate(FDP) was obtained by fermentation of bake yeast when starch was used as starting material. After converting and purification, the pure sodium FDP was obtained. The rate of yield was 10.5%. It was proved to be pure sodium FDP by optical rotation, layer chromatograph, enzymetic analysis, and NMR. Its purity was 115% of standard sample from Italy and compared with the rate of recovery of BaFDP, CaFDP, NaFDP respectively.
