A novel method for the synthesis of functional material

chiral sodium zincophosphate was studied

and the target product was obtained successfully with Na3PO4·12H2O and inorganic Zn salts as raw materials and PEG-400 as surfactant via a one step low heat solid state reaction.The influence of different kinds of Zn salts

P sources

and pH of the reaction mixture on the formation of the products was investigated.Experimental results indicated that the pH of the mixture was an important factor for regulation of the product structures.Different kinds of Zn salts did not affect the product structure

but different kinds of P sources affected the product structure through regulating pH.The influence of pH on the formation of the products was that when pH of the reaction mixture was about 11

7～9

about 5

about 3

the products were correspondingly (1) mixture of chiral NaZnPO4·H2O (P6122) and achiral NaZnPO4 (OH)［P21/c(14)］

(2) chiral NaZnPO4·H2O (P6122)

(3) achiral NaH (ZnPO4)2

(4) achiral Zn3 (PO4)2·4H2O.The reaction conditions for the synthesis of chiral NaZnPO4·H2O (P6122) were: Na3PO4·12H2O and inorganic Zn salts as raw materials

PEG-400 as surfactant

pH=7～9

P/Zn=1.18（mol） and the reaction mixture was aged at 50℃ for 6 h.
