在酸價(jià)測(cè)試中，氫氧化鉀也可作為一種主要的原料來輔助測(cè)試。作為一種較為常見的化學(xué)原料，氫氧化鉀有什么性質(zhì)、狀態(tài)、功能等常規(guī)概況呢？今天我們來了解一下。

Potassium hydroxide can also be used as a main raw material to assist in acid value testing. As a relatively common chemical raw material, what are the general properties, states, and functions of potassium hydroxide? Today, let's take a look.

氫氧化鉀除了學(xué)名外，還有很多別名，又稱苛性鉀、苛性堿、鉀灰等，它的化學(xué)式是KOH，其狀態(tài)主要是呈白色粉末或片狀固體。

In addition to its scientific name, potassium hydroxide also has many aliases, also known as caustic potassium, caustic soda, potassium ash, etc. Its chemical formula is KOH, and its state is mainly in the form of a white powder or sheet solid.

氫氧化鉀的熔點(diǎn)是380℃，沸點(diǎn)更是高達(dá)1324℃，算是很有“高冷”氣質(zhì)了。氫氧化鉀的相對(duì)密度是2.04g/cm2。

The melting point of potassium hydroxide is 380 ℃, and the boiling point is as high as 1324 ℃, which is considered a "high cold" temperament. The relative density of potassium hydroxide is 2.04g/cm2.

它具強(qiáng)堿性及腐蝕性，其性質(zhì)與燒堿相似。它易吸收空氣中水分而潮解，吸收二氧化碳而成碳酸鉀。當(dāng)它溶解于水、醇或用酸處理時(shí)會(huì)產(chǎn)生大量熱量。它也會(huì)溶于乙醇，微溶于醚。

It is highly alkaline and corrosive, and its properties are similar to those of caustic soda. It easily absorbs moisture in the air and deliquesces, absorbing carbon dioxide to form potassium carbonate. When dissolved in water, alcohol, or acid, it generates a large amount of heat. It is also soluble in ethanol and slightly soluble in ether.

從化學(xué)性質(zhì)方面來看，氫氧化鉀0.1mol/L溶液的pH為13.5，并且具有堿的通性，可使石蕊試液變藍(lán)、酚酞試液變紅，還可與酸、酸性氧化物、兩性金屬、兩性氧化物、兩性氫氧化物等發(fā)生化學(xué)反應(yīng)。

From the perspective of chemical properties, the pH of 0.1mol/L potassium hydroxide solution is 13.5, and it has alkali permeability, which can make litmus test solution turn blue and phenolphthalein test solution turn red. It can also undergo chemical reactions with acids, acidic oxides, amphoteric metals, amphoteric oxides, and amphoteric hydroxides.

氫氧化鉀的應(yīng)用領(lǐng)域很廣泛：

Potassium hydroxide has a wide range of applications:

其一，它可以運(yùn)用在干燥劑、吸收劑、制草酸及各種鉀鹽等方面，還可用于電鍍、雕刻、石印術(shù)等方面。

First, it can be used in desiccants, absorbents, oxalic acid production, and various potassium salts, as well as in electroplating, sculpture, lithography, and other fields.

其二，它還用作鉀鹽生產(chǎn)的原料，如高錳酸鉀、碳酸鉀等。在醫(yī)藥工業(yè)中，用于生產(chǎn)鉀硼氫、安體舒通、沙肝醇、丙酸睪丸素等。

Secondly, it is also used as a raw material for the production of potassium salts, such as potassium permanganate and potassium carbonate. In the pharmaceutical industry, it is used to produce potassium borohydride, spironolactone, salganol, testosterone propionate, etc.

在輕工業(yè)中用于生產(chǎn)鉀肥皂、堿性蓄電池、化妝品（如冷霜、雪花膏和洗發(fā)膏）。在染料工業(yè)中，用于生產(chǎn)還原染料，如還原藍(lán)RSN等。等等。

It is used in the production of potassium soap, alkaline batteries, and cosmetics (such as cold cream, snow cream, and shampoo) in the light industry. In the dye industry, it is used to produce vat dyes such as vat blue RSN. wait.

既然是說氫氧化鉀的常識(shí)，那么在了解它的應(yīng)用領(lǐng)域之后，也來了解一下它的另一些方面的常識(shí)。

Since this is the common sense of potassium hydroxide, after understanding its application fields, let's also learn about other aspects of it.

例如，它對(duì)組織有燒灼作用，可溶解蛋白質(zhì)，形成堿性變性蛋白質(zhì)。溶液或粉塵濺到皮膚上，尤其濺到黏膜，可產(chǎn)生軟痂。

For example, it has a cauterizing effect on tissues and can dissolve proteins to form alkaline denatured proteins. Solution or dust splashed onto the skin, especially onto the mucous membrane, can produce soft scabs.

溶液濃度越高，溫度越高，作用越強(qiáng)。濺入眼內(nèi)，不僅可損傷角膜，而且能使眼部深組織損傷。

The higher the concentration and temperature of the solution, the stronger the effect. Splash into the eye can not only damage the cornea, but also cause deep tissue damage in the eye.

氫氧化鉀的高容許濃度為0.5mg/m，所以在做與其有關(guān)的工作時(shí)，應(yīng)防止觸及皮膚和眼睛，做好防護(hù)，也是對(duì)自己和工作的負(fù)責(zé)。更多產(chǎn)品了解就來我們網(wǎng)站http://www.fahao168.com咨詢！

The high allowable concentration of potassium hydroxide is 0.5 mg/m3, so when doing work related to it, it is necessary to prevent contact with skin and eyes, and take good precautions. It is also responsible for oneself and work. For more product information, please visit our website http://www.fahao168.com consulting service
