檢查產(chǎn)品部分變質(zhì)的時(shí)候可以通過(guò)往當(dāng)中加入進(jìn)去過(guò)量氫氧化鉀一直等到完全沉淀，等到沉淀已經(jīng)靜止之后取上層的清液放置在試當(dāng)中，然后往當(dāng)中滴加無(wú)色的酚酞溶液，如果酚酞變紅了那么就說(shuō)明當(dāng)中是有堿性物質(zhì)的。通過(guò)文章對(duì)氫氧化鉀進(jìn)行簡(jiǎn)單的了解.

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、保證加氫反應(yīng)和氧化反應(yīng)工作液的pH值。蒽醌法生產(chǎn)雙氧水時(shí)，工作液的加氫是在堿性條件下進(jìn)行的。加氫液的氧化反應(yīng)和雙氧水的萃取必須在酸性條件下進(jìn)行。當(dāng)氧化液變?yōu)閴A性時(shí)，雙氧水會(huì)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、改進(jìn)堿處理工藝。當(dāng)堿處理過(guò)程出現(xiàn)異常時(shí)，氣體會(huì)帶出塔內(nèi)部分堿液。如果分離器沒(méi)有完全分離，工作液的堿度可達(dá)正常指示值的數(shù)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、嚴(yán)格控制氧化廢氣中的氧含量。氧化廢氣含有可燃?xì)怏w。在制造過(guò)程中分解時(shí)，混合廢氣中的氧濃度會(huì)超過(guò)15%，可形成爆性氣體混合物。因此，嚴(yán)格控制廢氣中的可燃?xì)怏w和氧氣含量是我們認(rèn)真考慮的問(wèn)題。生產(chǎn)中一般用氮?dú)庀♂屟趸瘡U氣，氧含量控制在10%以下，以保證生產(chǎn)。

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.

氫氧化鉀的一些知識(shí)我們今天就詳細(xì)的介紹到這里，希望會(huì)對(duì)大家有所幫助，對(duì)于氫氧化鉀的知識(shí)我們可以繼續(xù)關(guān)注官網(wǎng)http://www.tjxjw.com進(jìn)行詳細(xì)的了解。
