Synthesis Of Chiral And Achiral Alkali Zincophosphate Salts By Solid Phase Reaction At Low-Heating Temperature And Study Of Its Catalysis

Chapter One: The crystals of chiral sodium zincophosphate were synthesized via solid state reaction at low-heating temperature, when ZnSO₄·7H₂O reacts with Na₃PO₄·12H₂O using PEG-400 as template. The experimental results showed that (1) Chiral sodium zincophosphate was synthesized via solid state reaction at low-heating temperature for the first time, when ZnSO₄·7H₂O reacted with Na₃PO₄·12H₂O using PEG-400 as template. The products were characterized by XRD which indicated that the product was NaZnPO₄H₂O. (2) The products of chiral sodium zincophosphate had spontaneously crystallized to form ideal crystals within 20 minutes grinding time and warming at 60℃. On the contrary, the byproduct would be formed by long deposited time. (3)The products were synthesized by different phosphates and different zinc salts, pH value played key role in controlling composition of the products. (4) Adding glycine L—glutamate L—arginine, amino acid structure effected products structure. (5)Temperature played a key role in controlling the chiral structure. The products were chiral when the aged temperature was 60℃, and the products were achiral when the aged temperature was room temperature. (6)NaZnPO₄·H₂O with chiral and microporous structure has an ideal perspective catalysis.
