Potassium fluoride peroxosolvate KF-H2O2 was obtained upon action of a 30% aqueous solution of hydrogen peroxide on solid potassium fluoride dihydrate. As compared to other peroxosolvates, KF-H2O2 is characterized by the highest thermal stability: the decomposition rate constantk 1, at 120°C is 1.4 10−3 min−1, the enthalpy of H2O2 addition ...

氟化钾，是一种无机盐，化学式为KF，为白色结晶性粉末，味咸，易吸湿，溶于水，不溶于乙醇。 加热至升华温度时才少许分解，但熔融氟化钾的活性较大，能腐蚀耐火物质。 与过氧化氢可形成加成物KF·H2O2。 水合物有两种：KF·2H2O和KF·4H2O。 低于40.2℃时，水溶液中可结晶得到二水物（KF·2H2O），系单斜晶体，41℃时可自溶于结晶水中。 3、用作分析试剂、络合物形成剂。 也是制取氟化氢钾的原料； 4、可作为有机化合物的氟化剂。 皮肤接触：立即脱去污染的衣 …

1993年1月1日 · 过氧化钾氟化钾 KF-H2O2 是通过 30% 的过氧化氢水溶液对固体氟化钾二水合物的作用而获得的。与其他过氧溶剂化物相比，KF-H2O2 的特点是热稳定性最高：分解速率常数 k1，在 120°C 下为 1.4 10-3 min-1，H2O2 添加到 KF 的焓为 8.1 kcal/mol。

Decomposition of KF · H2O2 stabilized with carboxylic acids (maleic, fumaric, succinic, adipic) in storage for more than three years at 20°C was studied. Rate constants of decomposition of stabilized KF · H2O2 were determined in different time intervals.

H 2 O 2 is studied by X-ray diffraction analysis. It is shown that, on heating to 140°C under polythermal conditions, the peroxo solvate decomposes to form anhydrous potassium fluoride. The decomposition is accompanied by the appearance of extra reflections, which are presumably due to products of partial KF hydrolysis.
