对氢氧化钾的工艺生产保障你一定要知道的知识

发布来源:http://www.jinhao360.com    更新时间:2022-01-26 点击数:94

对氢氧化钾的工艺保障的知识,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.

For the knowledge of the process guarantee of potassium hydroxide, when checking the deterioration of some products, you can add excess potassium hydroxide into it until it is completely precipitated. After the precipitation has stopped, take the upper clear liquid and place it in the test, and then drop colorless phenolphthalein solution into it. If phenolphthalein turns red, it indicates that there are alkaline substances in it. Through this 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需要在酸性条件下进行。当氧化液变为碱性时,双氧水会引起事故。
1. Ensure the pH value of the working solution of hydrogenation reaction and oxidation reaction. In the production of hydrogen peroxide by anthraquinone method, the hydrogenation of working solution is carried out under alkaline conditions. The oxidation reaction of hydrogenation solution and the extraction of hydrogen peroxide need to be carried out under acidic conditions. When the oxidizing liquid becomes alkaline, hydrogen peroxide will 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 be brought out of the tower to separate the alkali liquor. 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,混合废气中的氧浓度会超过百分之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,氧含量控制在百分之十以下。
3. Strictly control the oxygen content in the oxidation waste gas. The oxidation waste gas contains combustible gas. In the manufacturing process, the oxygen concentration in the mixed exhaust gas will exceed 15%, which can form an explosive gas mixture. Therefore, strict control of combustible gas and oxygen content in waste gas is a problem we seriously consider. In production, nitrogen is generally used to dilute the oxidation waste gas, and the oxygen content is controlled below 10%.
