3、 Nature and Use

Boosting combustion, with strong corrosiveness and irritation, can cause burns to the human body. Slightly emitting smoke in the air. Stable at room temperature, decomposes at high temperatures, and accelerates decomposition in the presence of light and catalysts (such as aluminum chloride and activated carbon). It can react with many inorganic compound and many organic compounds. Under certain conditions, the reaction is more selective. When encountering cold water, it gradually decomposes, and when encountering hot water or alkali, it decomposes quickly, emitting irritating and corrosive hydrogen chloride gas. It is corrosive to many metals, especially in the presence of humid air. It is mainly used as chlorination agent or chlorosulfonation agent, such as the chlorination of aromatic compounds, carboxylic acids and other organic and inorganic compound, as well as in the manufacture of pharmaceuticals, dyes, surfactants, agents, organic chlorination agents, dyes, rubber, etc. It can also be used to treat wool fabrics.

4、 Packaging and Storage

The company uses plastic drums (specification: 300Kg) or tank cars for packaging. Store in a cool, dry, and well ventilated warehouse, away from sparks and heat sources. The temperature of the warehouse shall not exceed 25 ℃, and the relative humidity shall not exceed 75%. The packaging must be sealed and not affected by moisture. It should be stored separately from acids, alkalis, alcohols, etc., and avoid mixing storage.
