Trichloromethane

Trichloromethane, an organic compound, is a colorless transparent liquid with special smell, sweet taste, high refraction, nonflammable, heavy and volatile. It is sensitive to light. It reacts with oxygen in the air when exposed to light and gradually decomposes to produce highly toxic phosgene (carbonyl chloride) and hydrogen chloride. 0.6%~1% ethanol can be added as stabilizer.

Coal tar

Coal tar is one of the products of raw gas generated from coal pyrolysis in coking industry. Its output accounts for about 3%~4% of the charged coal. Its composition is extremely complex. In most cases, the coal tar industry is specialized in separation, purification and utilization. Under normal temperature and pressure, the product is black, and each fraction can be further processed to separate a variety of products, such as camphor pills, asphalt, plastics, pesticides, etc.

Solvent oil

Solvent oil is one of the five major categories of petroleum products. Solvent oil is widely used. The largest amount of solvent oil is paint solvent oil (commonly known as paint solvent oil), followed by edible oil, printing ink, leather, pesticides, pesticides, rubber, cosmetics, spices, medicine, electronic components and other solvent oils. At present, there are about 400-500 kinds of solvents on the market, of which solvent oils (hydrocarbon solvents, benzene compounds) account for about half.

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.
