三聚磷酸钠广泛用于合成洗涤剂工业,锅炉给水软化剂,肉禽食品添加剂等。工业三聚磷酸钠通常是三聚磷酸钠含量为85～95％,焦磷酸钠含量为4～15％,1％的正磷酸钠和偏磷酸钠等的混合物。对其组成的纸上色层定性分离,国内尚未报道。文献介绍,对三聚磷酸钠组分的分离,有上行纸上色层法,螺旋纸上色层法,离心纸上色层法。本文用国产新华3~#色层纸、以上行法,常温下对三聚磷酸钠组份进行定性分离,获得满意的分离图谱。
Sodium tripolyphosphate is widely used in the synthesis of detergent industry, boiler feed water softener, meat and poultry food additives. Industrial sodium tripolyphosphate is usually a mixture of sodium tripolyphosphate content of 85 to 95%, sodium pyrophosphate content of 4 to 15%, 1% sodium orthophosphate and sodium metaphosphate and the like. The composition of the paper color layer qualitative separation, not yet reported. Literature introduction, the separation of sodium tripolyphosphate components, the uplink paper color layer method, spiral color layer method, centrifugal paper color layer method. In this paper, China Xinhua 3 ~ # color paper, the above method, at room temperature sodium tripolyphosphate component qualitative separation, access to satisfactory separation map.
