氢氧化钾如何避免双氧水会分解,希望可以帮助到大家。
Today, I will show you how potassium hydroxide can avoid the decomposition of hydrogen peroxide. I hope it can help you.
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 oxidizing agent. The anthraquinone process was used as raw material and operated in an alkaline environment. The oxidation of the hydrogenation solution and the extraction of the peroxide need to be carried out in an acidic environment. The potassium hydroxide oxidation solution will be cracked when it becomes alkaline, thus causing 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. The potassium hydroxide alkali treatment technology was improved. Under abnormal conditions in the alkaline process, the generated gas is separated from the tower. In the case of insufficient separation, the alkalinity of the working liquid can reach several hundred times the standard index.
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. Oxidation tail gas is a flammable gas. In production, when the oxygen content in the mixed exhaust gas reaches more than 15%, an explosive gas will be produced. Therefore, the combustibles and oxygen in the tail gas must be strictly controlled. In order to ensure the safety of potassium hydroxide production, nitrogen is usually used to dilute the oxidation tail gas, and the oxygen concentration is not more than 10%.
此外要注意我们平时接触到的大部分氢氧化钾都不是一定纯的,很多产品通常都是根据自己的需要来使用的,那么使用时不同的浓度有什么区别呢?
In addition, it should be noted that most of the potassium hydroxide we usually contact is not necessarily pure. Many products are usually used according to their own needs. What is the difference between different concentrations when using?
1.其实这个产品本身的使用并没有什么特别的区别。只要加足剂量使用,效果其实很差。之所以在使用上会有一些差异,是因为和脂肪酸中和的程度不同。其实我们也可以看到,很多氢氧化钾等脂肪酸在水中的溶解度普遍有限,以于中和后产生的脂肪酸无法继续被中和。
1. In fact, there is no special difference in the use of this product. As long as the dosage is enough, the effect is actually very poor. The reason why there are some differences in use is that the degree of neutralization with fatty acids is different. In fact, we can also see that the solubility of many fatty acids such as potassium hydroxide in water is generally limited, so that the fatty acids produced after neutralization cannot be neutralized.
2.其实具体到用的浓度是多少,这个也和不同的工艺有很大的关系,所以其实在使用的时候,物质中的其他物质在使用不同浓度的时候可能会有一些影响,但其实这部分的影响都是比较小的。但是在制作肥皂的时候,有些人会发现有些问题可能是氢氧化钾浓度不够造成的,但其实这部分的问题是浓度的计算不够准确,只要我们确定了浓度再用合适的剂量处理就可以了。
2. In fact, the specific concentration used is also closely related to different processes. Therefore, in fact, other substances in the substance may have some impact when using different concentrations, but the impact of this part is relatively small. However, when making soap, some people may find that some problems may be caused by insufficient concentration of potassium hydroxide. However, the problem in this part is that the calculation of concentration is not accurate. As long as we determine the concentration and then treat it with appropriate dosage.
