氢氧化钾是一种无机化合物,化学式为KOH,是常见的无机碱,具有强碱性,溶于水、乙醇,微溶于乙醚,容易吸收空气中水分而潮解,吸收二氧化碳而成碳酸钾,主要用作加工钾盐的原料,也可用于电镀、印染等。那么氢氧化钾如何避免双氧水分解?
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、保证加氢和氧化剂的 pH。以蒽醌法为原料,在碱环境下进行了操作。加氢溶液的氧化及过氧化剂的提取均需在酸性环境中进行。 氢氧化钾氧化溶液在变成碱性后会发生裂解,从而导致事故。
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、对氢氧化钾碱处理技术进行了改进。在碱性工艺中发生不正常的情况下,将产生的气体从塔内分离出来。在不充分分离的情况下,工作液体的碱性可以达到几百倍于标准指标的水平。
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、对氧化尾气中氧气浓度进行严格控制。氧化尾气是一种易燃的气体。在生产中,当混合废气中的氧气含量达到15%以上时,就会产生一种爆炸气体。所以,须对尾气中的易燃物和氧进行严格的控制。为了确保氢氧化钾生产的安*性,通常采用氮气对氧化尾气进行稀释,氧气浓度不超过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%.
