　　食品級氫氧化鉀的使用方法

The use of food grade potassium hydroxide

　　1.食品添加劑。

1. Food additives.

　　2.用于制取其他鈉鹽、鉀鹽等，如碳酸氫銨、氯化銨和硝酸銨等；

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

　　3.在醫(yī)藥工業(yè)中用作制造抗組織胺藥物及解熱鎮(zhèn)痛藥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.在農(nóng)業(yè)上可用作肥料和農(nóng)藥，也可用作飼料添加劑。

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

　　氫氧化鉀是白色粉末或顆粒狀固體，無臭無味，易溶于水，水溶液呈弱堿性反應(yīng)（ph值約為9-10）。溶于甲醇、乙醇和丙酮等有機溶劑。

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.

　　其水溶液具有吸濕性，加熱會分解并產(chǎn)生氨氣與二氧化碳氣體。有潮解性且吸濕性強。穩(wěn)定性好于苛性鈉（koh），但低于硫酸鋁（na2s04）、三氧化硫（so3）。不溶于液氨及甘油而不發(fā)生沉淀現(xiàn)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.

　　在空氣中易風化而失去結(jié)晶水變成碳酸鉀而隨氣流飛揚；受熱時能吸收空氣中的水分而潮解；受強酸作用時則分解為堿式碳酸鉀和水蒸氣。

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.
