制备方法与用途

鉴别试验

1 g 试样可溶于 100 mL 的 4% 醋酸钠溶液中。其火焰焰色反应呈淡紫色。取 0.1 g 试样,加水 10 mL 和醋酸钠 0.4 g,溶解后加入稀醋酸液(TS-2)使成弱酸性,当加入 3 mL 硝酸银试液(TS-210)时,应即有白色沉淀产生。取 0.5 g 试样,加硝酸 10 mL 和水 50 mL 混合,煮沸约 30 min 后冷却。该溶液的磷酸盐试验(IT-26)和钾试验(IT-27)呈阳性。取 1 g 试样研成细粉,缓慢加于 2% 氯化钠溶液 100 mL 中,并强烈搅拌,应形成凝胶状物质。

含量分析

精确称取约 300 mg 试样,加硝酸 15 mL 和水 30 mL,混合后煮沸 30 min。用水稀释至 100 mL,在 60℃ 下加热,加入过量的钼酸铵试液(TS-22),于 50℃ 下加热 30 min。过滤并用稀硝酸(1 mL 溶于 36 mL 水)洗涤沉淀,然后用 1% 硝酸钾溶液洗涤,直至滤出液不再呈酸性(以石蕊为标准)。将沉淀溶于 50 mL 1.0 mol/L 的氢氧化钠溶液中,并加酚酞试液(TS-167)数滴。用 1.0 mol/L 硫酸滴定剩余的氢氧化钠,每毫升 1.0 mol/L 氢氧化钠相当于 P205 3.086 mg。

毒性

ADI 为 0~70(以 P 计的磷酸盐总量;FAO/WHO,2001)。大剂量时有致肾结石的报道。

使用限量

化学性质

高度聚合的直链型聚磷酸盐,可能含少量环状结构的三偏磷酸钾及四偏磷酸钾等。为无色至白色玻璃状块或片,或白色纤维状结晶或粉末,无臭。在水中缓慢溶解,其溶解度随聚合度而异,一般约为 0.004%。水溶液呈碱性,溶于钠盐溶液,在稀的无机酸中可迅速溶解,不溶于乙醇。

用途

脂肪乳化剂;保湿剂;水的软化剂;金属离子螯合剂;组织改进剂(主要用于水产调味品),用量为 0.6%~1.2%;干制品;鱼糜制品,用量为 0.1%;冰淇淋,用量为 0.03%~0.1%;蛋白沉淀剂等。

用途

生产方法

由磷酸氢二钾与磷酸二氢钾混合后加热脱水而成,其主成分为三聚磷酸钾。

生产方法

一般由磷酸二氢钾在 400~700℃(理论上 200℃ 左右即可)下加热数小时进行分子内脱水缩合作用。成品的聚合度取决于加热温度和时间,为提高聚合度亦可用 850℃ 进行缩合。

    摘要:
    我们通过角色散粉末同步加速器 X 射线衍射研究了 KCaPO 4、SrKPO 4和 K 2 Ce(PO 4 ) 2在分别高达 26、25 和 22 GPa 的高压下的结构行为。对于 KCaPO 4,我们还准确地确定了环境条件下的晶体结构,这与之前报道的结构不同。将讨论支持我们的结构决定的论点。我们已经发现KCaPO 4经历了可逆的相变。转变开始于 5.6 GPa。它涉及对称性降低。低压相由空间群P 3̅ m描述1 和空间群Pnma的高压相。对于KSrPO 4和K 2 Ce(PO 4 ) 2,在达到实验所涵盖的最高压力之前没有发现相变的证据。对于这三种化合物,报告了不同晶轴的线性压缩率和压力-体积状态方程,并与其他磷酸盐进行了比较。所研究的三种化合物属于最可压缩的磷酸盐。该研究的结果提高了对复合磷酸盐高压行为的认识。
