Sodium peroxycarbonate is an inorganic compound, also known as sodium percarbonate or peroxycarbonate, with the chemical formula 2Na2CO3 · 3H2O2. It has strong oxidizing and alkaline, so it has a wide range of uses in the field of chemical production raw materials. This article will detail the properties and uses of sodium percarbonate.

1. The properties of sodium peroxycarbonate

1. Physical properties

sodium peroxycarbonate is a white crystalline powder, odorless, tasteless, and hygroscopic. It dissolves easily in water and the solution is alkaline.

2. chemical properties of

sodium peroxycarbonate has strong oxidation, acid, heat or by friction, vibration, impact can be decomposed, release oxygen, while generating sodium carbonate. When it comes into contact with organic matter, it can cause combustion or explosion.

II, the use of sodium peroxycarbonate

1. Bleach

Sodium peroxycarbonate can be used as bleaching agent, used for bleaching of cotton, hemp, chemical fiber and other fabrics, can also be used for food, beverage, medicine and other industries bleaching. Because the oxygen produced after its decomposition has a bleaching effect, sodium peroxide can effectively remove stains and colors without damaging the fabric fibers.

2. oxidizing agent

Sodium peroxycarbonate can be used as an oxidizing agent for removing iron and manganese from water and oxidizing organic substances. In water treatment, sodium percarbonate can improve the transparency and taste of water, and remove the odor and color in the water.

3. cleaning agent

sodium peroxide can be used as a cleaning agent for washing tableware, kitchenware, bathroom, etc. Because of its strong oxidizing and alkaline, it can quickly remove oil stains, tea stains and other stains, and has the effect of sterilization and disinfection.

4.

of food additives Sodium peroxycarbonate can be used as food additives for pasta, meat products, dairy products and other foods, as a quality improver and preservative. In pasta, sodium percarbonate can make pasta more gluten and elastic; in meat products, sodium percarbonate can inhibit bacterial growth and extend shelf life; in dairy products, sodium percarbonate can improve taste and quality.

In short, sodium percarbonate as an important chemical production raw materials, has a wide range of uses. It is necessary to pay attention to safety during use and avoid contact with organic matter, acid and other substances to avoid combustion or explosion.
