氫氧化鉀是一種無(wú)機(jī)化合物，化學(xué)式為KOH，是常見(jiàn)的無(wú)機(jī)堿，具有強(qiáng)堿性，溶于水、乙醇，微溶于乙醚，容易吸收空氣中水分而潮解，吸收二氧化碳而成碳酸鉀，主要用作加工鉀鹽的原料，也可用于電鍍、印染等。那么氫氧化鉀如何避免雙氧水分解？

Potassium hydroxide is a inorganic compound with the chemical formula of KOH. It is a common inorganic base. It is strongly alkaline, soluble in water, ethanol, and slightly soluble in ether. It is easy to absorb moisture in the air and deliquescence. It absorbs carbon dioxide to form potassium carbonate, which is mainly used as raw material for processing potassium salt, and can also be used for electroplating, printing and dyeing. So how can potassium hydroxide avoid the decomposition of hydrogen peroxide?

1、保證加氫和氧化劑的 pH。以蒽醌法為原料，在堿環(huán)境下進(jìn)行了操作。加氫溶液的氧化及過(guò)氧化劑的提取均需在酸性環(huán)境中進(jìn)行。 氫氧化鉀氧化溶液在變成堿性后會(huì)發(fā)生裂解，從而導(dǎo)致事故。

1. Ensure the pH of hydrogenation and oxidants. The anthraquinone method was used as the raw material and operated in an alkaline environment. The oxidation of hydrogenation solutions and the extraction of peroxides need to be carried out in an acidic environment. Potassium hydroxide oxidation solution will undergo cracking after becoming alkaline, leading to accidents.

2、對(duì)氫氧化鉀堿處理技術(shù)進(jìn)行了改進(jìn)。在堿性工藝中發(fā)生不正常的情況下，將產(chǎn)生的氣體從塔內(nèi)分離出來(lái)。在不充分分離的情況下，工作液體的堿性可以達(dá)到幾百倍于標(biāo)準(zhǔn)指標(biāo)的水平。

2. Improvements have been made to the alkaline treatment technology of potassium hydroxide. In the alkaline process, abnormal conditions occur and the generated gas is separated from the tower. Without sufficient separation, the alkalinity of the working liquid can reach a level several hundred times higher than the standard indicator.

3、對(duì)氧化尾氣中氧氣濃度進(jìn)行嚴(yán)格控制。氧化尾氣是一種易燃的氣體。在生產(chǎn)中，當(dāng)混合廢氣中的氧氣含量達(dá)到15%以上時(shí)，就會(huì)產(chǎn)生一種爆炸氣體。所以，須對(duì)尾氣中的易燃物和氧進(jìn)行嚴(yán)格的控制。為了確保氫氧化鉀生產(chǎn)的安*性，通常采用氮?dú)鈱?duì)氧化尾氣進(jìn)行稀釋?zhuān)鯕鉂舛炔怀^(guò)10%。

3. Strictly control the oxygen concentration in the oxidation tail gas. Oxidized exhaust gas is a flammable gas. In production, when the oxygen content in the mixed exhaust gas reaches over 15%, an explosive gas will be generated. Therefore, it is necessary to strictly control the flammable substances and oxygen in the exhaust gas. To ensure the safety of potassium hydroxide production, nitrogen is usually used to dilute the oxidation tail gas, with an oxygen concentration not exceeding 10%.
