27495-40-5 - Introduction
protostemonine, chemical formula for NaOH, also known as sodium hydroxide, is a common alkaline compound. It has the following properties:
1. Physical properties: protostemonine is a white solid, soluble in water, strong alkaline in water, can quickly absorb moisture and corrosion of many materials, including skin and eyes. It is hygroscopic and should be stored in a dry and ventilated place.
2. Chemical properties: protostemonine is a strong base, can react with acid to generate the corresponding salt and water. It can also form hydroxide precipitates with metal ions, and reacts with metals such as aluminum and zinc to release hydrogen. It is also corrosive and can corrode organic matter.
protostemonine has a wide range of uses:
1. Industrial use: protostemonine is an important raw material for the manufacture of soap, paper, soda, cellulose, glass and other chemical products. It is also used in water treatment, metal surface treatment and stone alkali production.
2. Laboratory use: protostemonine in the laboratory is often used as acid and alkali neutralization reaction, adjust the pH value of the solution, remove acidic substances.
protostemonine preparation method mainly has the following kinds:
1. Sodium chloride electrolysis method: Through the electrolysis of saturated sodium chloride solution, chlorine gas into saturated sodium chloride solution, so that the oxidation-reduction reaction, so as to produce protostemonine.
2. Reaction method of sodium carbonate and limestone: sodium carbonate reacts with limestone to generate calcium hydroxide, and then reacts with water to generate protostemonine.
When using protostemonine, pay attention to safety matters:
1. Wear protective gloves, goggles and protective clothing to avoid skin and eye damage from contact with protostemonine.
2. Be careful to avoid splashing powder or solution into the air during operation to reduce the risk of inhaling gas.
3. Should avoid storage with acids, flammable substances, etc., to prevent the occurrence of dangerous chemical reactions.
The above is a brief introduction to the nature, use, formulation and safety information of protostemonine.
