三偏磷酸钠制备

1.磷酸二氢钠法是简单而常用的制法。
磷酸二氢钠法将食用磷酸二氢钠加热，于95℃脱水成为无水磷酸二氢钠，然后送人箱式聚合炉中加热熔融聚合，当物料温度在140～200℃时，先转化成酸式焦磷酸钠，再加热至260℃时转化成环状偏磷酸钠，再加热至500℃时聚合成三偏磷酸钠，经冷却，粉碎，制得食用三偏磷酸钠成品。其
2.将60g磷酸二氢钠与17g硝酸铵的混合物在310～320℃加热6h，冷却后将混合物溶于冷水中，过滤，将滤液结晶，得到六水环三偏磷酸钠。 3. 由五氧化二磷与碳酸钠在4 7 5~5 0 0℃下共热制得。反应式如下: 3 P 2O 5+3 N a 2C O3 → 2 N a 3P 3O 9+3 C O 2
