Chlorine

Chlorine is a non-metallic element with the element symbol Cl, atomic number 17, located in the third cycle, group VII A, and one of the halogen elements. Chlorine is composed of two chlorine atoms, with the chemical formula of Cl2. Gaseous chlorine is commonly known as chlorine, and liquid chlorine is commonly known as liquid chlorine. Chlorine is yellow green gas under normal temperature and pressure, with strong pungent smell, very active chemical property and toxicity. Chlorine exists widely in nature in the form of compound, which is also of great significance to human physiological activities.

Hydrogen peroxide

Hydrogen peroxide is an inorganic compound. Pure hydrogen peroxide is a light blue viscous liquid, which can be miscible with water in any proportion. It is a strong oxidant. The aqueous solution is commonly known as hydrogen peroxide, which is a colorless transparent liquid. Its aqueous solution is suitable for medical wound disinfection, environmental disinfection and food disinfection. Generally, it will slowly decompose into water and oxygen, but the decomposition speed is extremely slow. The way to speed up the reaction speed is to add catalyst manganese dioxide or use short wave radiation.

Dimethylamine solution

Dimethylamine is also known as N, N-dimethylamine. Because of its low boiling point (6.9 ℃), it is a gas at room temperature, flammable and explosive. If pressurized liquefaction is adopted, it needs to be stored and transported in pressure resistant steel cylinders, which is inconvenient for transportation and use, especially for enterprises that do not have a dimethylamine production device and use dimethylamine as production raw material. Dimethylamine is easily soluble in water, and 40% aqueous solution is easy to manufacture, transport and use, safe and energy-saving. Therefore, 40% dimethylamine aqueous solution becomes an industrial product, called "industrial dimethylamine aqueous solution". It can be directly used in industry or used to evaporate dimethylamine. Therefore, its properties and uses are the same as those of dimethylamine.

Liquefied petroleum gas (LPG)

Liquefied petroleum gas (LPG) is a colorless volatile liquid obtained from natural gas or petroleum through pressurization and cooling liquefaction in the refinery. It is very easy to self ignite. When its content in the air reaches a certain concentration range, it will explode when encountering open fire.

Natural gas

Natural gas refers to all gases naturally existing in nature, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere (including oilfield gas, gas field gas, mud volcanic gas, coalbed gas, and biogenic gas)

Methylbenzene

Toluene is an organic compound with the chemical formula of C7H8. It is a colorless, volatile liquid with special fragrance. It has strong refraction. It is miscible with ethanol, ether, acetone, chloroform, carbon disulfide and glacial acetic acid, and very slightly soluble in water. Flammable, vapor can form explosive mixture with air, and explosion can occur when the volume concentration of the mixture is in a low range. Low toxicity, median lethal dose (rat, oral) 5000mg/kg. High concentration gas is anesthetic and irritant.
