今天小編帶大家了解一下
氫氧化鉀如何避免雙氧水會分解,希望可以幫助到大家。
Today, I will show you how potassium hydroxide can avoid the decomposition of hydrogen peroxide. I hope it can help you.
1、保證加氫和氧化劑的pH。以蒽醌法為原料,在堿環(huán)境下進行了操作。加氫溶液的氧化及過氧化劑的提取均需在酸性環(huán)境中進行。氫氧化鉀氧化溶液在變成堿性后會發(fā)生裂解,從而導致事故。
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、對氫氧化鉀堿處理技術進行了改進。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。在不充分分離的情況下,工作液體的堿性可以達到幾百倍于標準指標的水平。
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、對氧化尾氣中氧氣濃度進行嚴格控制。氧化尾氣是一種易燃的氣體。在生產(chǎn)中,當混合廢氣中的氧氣含量達到15%以上時,就會產(chǎn)生一種爆炸氣體。所以,須對尾氣中的易燃物和氧進行嚴格的控制。為了確保氫氧化鉀生產(chǎn)的安*性,通常采用氮氣對氧化尾氣進行稀釋,氧氣濃度不超過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%.
此外要注意我們平時接觸到的大部分氫氧化鉀都不是一定純的,很多產(chǎn)品通常都是根據(jù)自己的需要來使用的,那么使用時不同的濃度有什么區(qū)別呢?
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.其實這個產(chǎn)品本身的使用并沒有什么特別的區(qū)別。只要加足劑量使用,效果其實很差。之所以在使用上會有一些差異,是因為和脂肪酸中和的程度不同。其實我們也可以看到,很多氫氧化鉀等脂肪酸在水中的溶解度普遍有限,以于中和后產(chǎn)生的脂肪酸無法繼續(xù)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.其實具體到用的濃度是多少,這個也和不同的工藝有很大的關系,所以其實在使用的時候,物質(zhì)中的其他物質(zhì)在使用不同濃度的時候可能會有一些影響,但其實這部分的影響都是比較小的。但是在制作肥皂的時候,有些人會發(fā)現(xiàn)有些問題可能是氫氧化鉀濃度不夠造成的,但其實這部分的問題是濃度的計算不夠準確,只要我們確定了濃度再用合適的劑量處理就可以了。
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.
