氫氧化鉀可從電解高純度的氯化鉀水溶液制得。所用的電解槽形式以及生產(chǎn)過程類似氫氧化鈉。使用隔膜電解槽時，所得的電解液含有10％～15％(質(zhì)量)的氫氧化鉀和約10％（質(zhì)量）的氯化鉀。

Potassium hydroxide can be prepared by electrolysis of high-purity potassium chloride aqueous solution. The type of electrolytic cell used and the production process are similar to sodium hydroxide. When diaphragm electrolyzer is used, the electrolyte obtained contains 10%~15% (mass) potassium hydroxide and about 10% (mass) potassium chloride.

經(jīng)蒸發(fā)、濃縮、冷卻，大部分的氯化鉀結晶析出，分離后得到含氫氧化鉀45％～50％的產(chǎn)品(含氯化鉀0.6％)。采用水銀電解法可以制得高純度的氫氧化鉀，但應控制氯化鉀水溶液中重金屬雜質(zhì)的含量在0.1ppm以下,以免氯氣中含氫過高。

After evaporation, concentration and cooling, most potassium chloride crystals are separated, and the product containing 45%~50% potassium hydroxide (containing 0.6% potassium chloride) is obtained after separation. High purity potassium hydroxide can be prepared by mercury electrolysis, but the content of heavy metal impurities in potassium chloride aqueous solution should be controlled below 0.1 ppm to avoid excessive hydrogen content in chlorine.

采用離子膜電解法須使用專用的離子交換膜。氫氧化鉀比氫氧化鈉難于脫水。工業(yè)固體氫氧化鉀的純度為88％～92％，固體有塊狀和片狀兩種。液體氫氧化鉀有45％和50％兩種濃度規(guī)格。

Ion exchange membrane shall be used for ion-exchange membrane electrolysis. Potassium hydroxide is harder to dehydrate than sodium hydroxide. The purity of industrial solid potassium hydroxide is 88%~92%. There are two kinds of solid: blocky and flaky. There are two concentration specifications of liquid potassium hydroxide: 45% and 50%.

無機工業(yè)用作生產(chǎn)鉀鹽，如高錳酸鉀、亞硝酸鉀、磷酸氫二鉀等的原料。日化工業(yè)用作制造鉀肥皂、洗污肥皂、洗頭軟皂、雪花膏、冷霜、洗發(fā)膏等的原料。制藥工業(yè)用于制造黃體酮、香蘭素等原料。

Inorganic industry is used as raw materials for the production of potassium salts, such as potassium permanganate, potassium nitrite, potassium hydrogen phosphate, etc. The daily chemical industry is used as the raw material for manufacturing potassium soap, dirt washing soap, shampoo, cream, cold cream, shampoo, etc. The pharmaceutical industry is used to manufacture such raw materials as progesterone and vanillin.

染料工業(yè)用于制造三聚氰胺染料。電池工業(yè)用于制造堿性蓄電地。用作皂化試劑、二氧化碳和水分的吸收劑，分析試劑，堿性劑；可用作制品發(fā)色劑，冶金加熱劑和皮革脫脂等方面；用作干燥劑、吸收劑，還用于電鍍、雕刻、石印術等。

The dye industry is used to make melamine dyes. The battery industry is used to manufacture alkaline storage ground. Used as saponification reagent, absorbent of carbon dioxide and water, analytical reagent and alkaline agent; It can be used as product chromogenic agent, metallurgical heating agent, leather degreasing, etc; It is used as desiccant, absorbent, electroplating, carving, lithography, etc.
