You often hear that sodium hydroxide is alkaline. Because of its properties, it can be used to make soap. But do you know the steps to make soap with it? Let's talk about it next. I hope it can help you.

We have heard that potassium hydroxide will appear some black when it is being produced. That's because some of the substances are affected by the production, or there are some problems in the process. But sometimes it will appear red when it is being produced. Why.

The chemical formula of KOH is white powder or flake solid. Its melting point is 380 ℃, and its boiling point is 1324 ℃. It has the characteristics of strong alkali and corrosiveness.

Have you heard that sodium hydroxide can be used to remove a lot of heavy oil substances when it is used, but actually we all know that sodium hydroxide itself is relatively alkaline when it is used, so when it is used, the injuries to hands and other injuries are also serious,

Food grade hydrogen peroxide shall be packed in polyethylene barrels that meet the requirements of food hygiene, and the cover of the packaging containers shall be provided with small vent holes.

Potassium hydroxide is an alkaline substance that we learned in junior high school, and it has a very good use effect in many fields. When it is used, some people will question whether it is related to micro arc oxidation of magnesium alloy.

Nitric acid in nature is mainly formed by nitric oxide generated in thunderstorm days or nitrogen dioxide released from microbial life activities. Human activities also produce nitrogen oxides. There are many nitrogen oxides discharged from human pollution sources every year in the world,

According to the analysis, "from the end of last year to now, nitrogen, phosphorus and compound fertilizers have increased in varying degrees, with the increase ranging from 500-700 yuan / ton."

According to the introduction of general manager Liu of Tongli Chemical Co., Ltd., the fertilizers as excellent potassium sources are potassium nitrate, potassium sulfate, potassium dihydrogen phosphate and potassium chloride, with the following differences:

1. The world's advanced one-step hydrolysis of methyl formate to produce formic acid. That is to say, carbon monoxide and methanol generate methyl formate under the action of catalyst. Methyl formate and non-ionic water are hydrolyzed at a certain temperature and pressure.
