食品级氢氧化钾的使用方法

The use of food grade potassium hydroxide

　　1.食品添加剂。

1. Food additives.

　　2.用于制取其他钠盐、钾盐等，如碳酸氢铵、氯化铵和硝酸铵等；

2. Used to produce other sodium and potassium salts, such as ammonium bicarbonate, ammonium chloride, and ammonium nitrate;

　　3.在医药工业中用作制造抗组织胺药物及解热镇痛药阿司匹林的重要原材料；

3. Used as an important raw material in the pharmaceutical industry for manufacturing antihistamines and antipyretic analgesics such as aspirin;

　　4.在农业上可用作肥料和农药，也可用作饲料添加剂。

4. It can be used as fertilizer, pesticide, and feed additive in agriculture.

　　氢氧化钾是白色粉末或颗粒状固体，无臭无味，易溶于水，水溶液呈弱碱性反应（ph值约为9-10）。溶于甲醇、乙醇和丙酮等有机溶剂。

Potassium hydroxide is a white powder or granular solid, odorless and tasteless, easily soluble in water. The aqueous solution exhibits a weak alkaline reaction (pH value is about 9-10). Soluble in organic solvents such as methanol, ethanol, and acetone.

　　其水溶液具有吸湿性，加热会分解并产生氨气与二氧化碳气体。有潮解性且吸湿性强。稳定性好于苛性钠（koh），但低于硫酸铝（na2s04）、三氧化硫（so3）。不溶于液氨及甘油而不发生沉淀现象。

Its aqueous solution has hygroscopicity, and heating will decompose and produce ammonia and carbon dioxide gases. Has deliquescence and strong moisture absorption. Stability is better than caustic soda (koh), but lower than aluminum sulfate (na2s04) and sulfur trioxide (so3). Insoluble in liquid ammonia and glycerol without precipitation.

　　在空气中易风化而失去结晶水变成碳酸钾而随气流飞扬；受热时能吸收空气中的水分而潮解；受强酸作用时则分解为碱式碳酸钾和水蒸气。

Easy to weather in the air and lose crystalline water, turning into potassium carbonate and flying with the airflow; When heated, it can absorb moisture from the air and deliquescence; When subjected to strong acid action, it decomposes into basic potassium carbonate and water vapor.
