六偏磷酸钠 制备方法及用途

制备方法

将氢氧化钠加入磷酸,在540~580℃下加热脱水约2h,所得者为稳定态的I型(Na:P=5:3);如先加热至620℃熔融,然后在550℃下脱水,再在空气中冷却至100~150'℃,所得者为亚稳定态的Ⅱ型。

合成制备方法

 1.磷酸二氢钠法将纯碱溶液与磷酸在80~100℃进行中和反应2h,生成的磷酸二氢钠溶液经蒸发浓缩、冷却结晶,制得二水磷酸二氢钠,加热至110~230℃脱去2个结晶水,继续加热脱去结构水,进一步加热至620℃时脱水,生成的偏磷酸钠熔融物,并聚合成六偏磷酸钠。然后卸出,从650℃骤冷至60~80℃时制片,经粉碎制得六偏磷酸钠成品。其

2.五氧化二磷法将黄磷在干燥空气流中燃烧氧化、冷却而得的五氧化二磷与纯碱按一定比例(Na2O:P2O5=1~1.1)混合。将混合粉料于石墨坩埚中间接加热使其脱水熔聚,生成的六偏磷酸钠熔体经骤冷制片、粉碎,制得工业六偏磷酸钠成品。其

3.将试剂磷酸二氢钠加热至700~900℃熔融,当熔融物完全透明,内部气泡消失后,骤冷至60~80℃,得到薄片玻璃状产品,即为六偏磷酸钠:

4.将 试 剂 磷 酸 二 氢 钠 加 热 至250℃,骤冷,可得偏磷酸钠的二聚物;加热至650℃,骤冷,得六偏磷酸钠。

5.磷酐法 将黄磷加热熔融后,送入氧化燃烧炉中,用干燥空气中的氧进行氧化燃烧反应,生成中间产品磷酐。再将磷酐与纯碱混合后,经高温聚合反应,骤冷制片即得片状六偏磷酸钠;经粉碎可得粉状六偏磷酸钠。

6.中和聚合法 工艺流程如下:

将磷酸和液体氢氧化钠分别经各自的批量控制器(控制每批液碱、酸投入量,可自动配料,加料速度可在0~20L/min范围内任意调节),按要求加入量连续、准确地加入到中和槽中进行中和反应,反应完成后,pH值达4~4.4,生成磷酸氢二钠,通过中和液泵送入高位槽。将一定量的磷酸氢二钠连续、均匀送到干燥机中干燥,得到规定水分含量的片状磷酸氢二钠,再连续地送入由特殊耐腐蚀材料制成的经柴油燃烧的高温(750~850℃)聚合炉中,使磷酸氢二钠熔融聚合;熔融物料经从聚合炉中连续流出,经骤冷压片即得片状六偏磷酸钠,破碎、筛分得产品。

用途简介

在食品工业中作为品质改良剂、PH调节剂、金属离子螯合剂、粘合剂和膨胀剂。在豆类、罐头、豆沙馅料中能稳定天然色素,保持色泽;在罐头中可使脂肪乳化,保持质地均匀;用于肉类罐头和肉制品可提高保水性,防止脂肪变质。加入啤酒中,能澄清酒液,防止混浊。是优良的水质无沉淀的软水剂。在水产品加工中起着保水、膨胀和漂白的作用。

用途

1.最常用的聚磷酸有六偏磷酸钠和三聚磷酸钠。从缓蚀效果看,六偏磷酸钠优于三聚磷酸钠,因此,六偏磷酸钠使用更为广泛。

2.用作锅炉用水和工业用水(包括染料生产用水,钛白粉生产用水,印染调浆和染色用水,清洗彩色电影拷贝用水,以及化工用水,药品、试剂生产用水等)的软水剂,工业循环冷却水的水处理剂;还用作缓蚀剂,浮选剂,分散剂,高温结合剂,染色助剂,金属表面处理、防锈剂,洗涤剂助剂,水泥硬化促进剂。铜版纸生产用作浆料扩散剂,以提高渗透力。此外还用于洗涤器皿和化学纤维中用以除去浆粕中的铁离子。石油工业中用于钻探管的防锈和控制石油钻井时调节泥浆的黏度。

3.用作分析试剂,如作掩蔽剂。还用作软水剂。也用于照相洗印和印染业。胶黏剂中主要用作分散剂、防沉剂。工业上用作软水剂、缓蚀剂、防锈剂、水泥硬化促进剂、扩散剂等。
