摘要

对合成多孔功能材料手性磷酸锌钠的新方法进行了研究，以聚乙二醇-400 （PEG-400）为表面活性剂，Na3PO4·12H2O和无机锌盐为原料，用低热固相反应一步法成功合成得到P6122空间群的手性NaZnPO4·H2O。实验考察了不同的锌盐、磷酸盐，以及不同pH值对产物的影响。结果表明， pH值起着重要的作用，其调控着产物的结构;锌盐的种类不影响产物的结构;磷酸盐的种类则通过pH值的调控作用对产物产生影响。当pH在11、7～9、5、3左右时，得到的产物分别为(1) P6122空间群的手性NaZnPO4·H2O与非手性的NaZnPO4(OH)的混合物;(2)P6122空间群的手性的 NaZnPO4·H2O;(3)非手性的NaH(ZnPO4)2;(4)非手性的Zn3(PO4)2·4H2O。以PEG-400为表面活性剂，Na3PO4·12H2O及无机锌盐为原料，在P/Zn=1.18（摩尔比），pH=7～9，反应混合物于50℃陈化6 h的条件下，合成产物为手性NaZnPO4·H2O。

Abstract

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.
