检查产品部分变质的时候可以通过往当中加入进去过量氢氧化钾一直等到完全沉淀，等到沉淀已经静止之后取上层的清液放置在试当中，然后往当中滴加无色的酚酞溶液，如果酚酞变红了那么就说明当中是有碱性物质的。通过文章对氢氧化钾进行简单的了解.

When checking whether the product is partially deteriorated, you can add excessive potassium hydroxide into it until it is completely precipitated. After the precipitate is still, take the supernatant of the upper layer and place it in the test, and then drop a colorless phenolphthalein solution into it. If the phenolphthalein turns red, it means there is alkaline substance in it. Through the article, we have a simple understanding of potassium hydroxide

1、保证加氢反应和氧化反应工作液的pH值。蒽醌法生产双氧水时，工作液的加氢是在碱性条件下进行的。加氢液的氧化反应和双氧水的萃取必须在酸性条件下进行。当氧化液变为碱性时，双氧水会分解而引起事故。

1. Ensure the pH value of hydrogenation reaction and oxidation reaction working solution. When anthraquinone method is used to produce hydrogen peroxide, the hydrogenation of working solution is carried out under alkaline conditions. The oxidation reaction of hydrogenation solution and the extraction of hydrogen peroxide must be carried out under acidic conditions. When the oxidation solution becomes alkaline, hydrogen peroxide will decompose and cause accidents.

2、改进碱处理工艺。当碱处理过程出现异常时，气体会带出塔内部分碱液。如果分离器没有完全分离，工作液的碱度可达正常指示值的数百倍。

2. Improve the alkali treatment process. When the alkali treatment process is abnormal, the gas will take out the alkali liquor inside the tower. If the separator is not completely separated, the alkalinity of the working fluid can reach hundreds of times of the normal indicated value.

3、严格控制氧化废气中的氧含量。氧化废气含有可燃气体。在制造过程中分解时，混合废气中的氧浓度会超过15%，可形成爆性气体混合物。因此，严格控制废气中的可燃气体和氧气含量是我们认真考虑的问题。生产中一般用氮气稀释氧化废气，氧含量控制在10%以下，以保证生产。

3. Strictly control the oxygen content in oxidation waste gas. The oxidation waste gas contains combustible gas. When decomposed in the manufacturing process, the oxygen concentration in the mixed exhaust gas will exceed 15%, which can form explosive gas mixture. Therefore, strict control of the combustible gas and oxygen content in the exhaust gas is a serious consideration. The oxidation waste gas is generally diluted with nitrogen during production, and the oxygen content is controlled below 10% to ensure production safety.
