Sulfur dioxide

Sulfur dioxide is the most common, simple and irritating sulfur oxide, chemical formula SO2, colorless gas. Volcanic eruptions emit this gas, and sulfur dioxide is also produced in many industrial processes. As coal and oil usually contain sulfur, sulfur dioxide will be generated when burning. When sulfur dioxide is dissolved in water, it will form sulfite.

Chloroethane

Chloroethane, also known as ethyl chloride, is an organic compound. It is a colorless gas under normal temperature and pressure, has an ether like odor, slightly soluble in water, and miscible in most organic solvents. It is mainly used as a raw material for tetraethyl lead, ethyl cellulose, etc. It can also be used as a refrigerant, anesthetic, insecticide, aerosol, ethylating agent, etc. It can also be used as a catalyst for polypropylene, and as a solvent for phosphorus, sulfur, grease, resin, wax, etc.

Hydrogen peroxide

Hydrogen peroxide, an aqueous solution of hydrogen peroxide, is commonly used for sterilization. Hydrogen peroxide solution (content greater than 8%) is an explosive chemical. It can have oxidation or reduction under different conditions. It can be used as oxidant, bleach, disinfectant, dechlorinating agent, as well as for making rocket fuel, organic or inorganic peroxide, foam plastic and other porous materials.

Chloromethane

Methyl chloride, also known as methyl chloride, is an organic compound. It is a colorless gas under normal temperature and pressure, slightly soluble in water, and soluble in ethanol, chloroform, benzene, carbon tetrachloride, glacial acetic acid, etc. It is mainly used as the raw material of organic silicon, as well as as solvent, refrigerant, perfume, etc.
