N-hexane

N-hexane, also known as hexane, is a straight chain saturated fatty hydrocarbon obtained by crude oil cracking and distillation, and is a colorless liquid with a weak and distinctive odor. It is volatile, almost insoluble in water, and easily soluble in chloroform, ether, and ethanol. Mainly used as solvents, such as vegetable oil extraction solvents, propylene polymerization solvents, rubber and coating solvents, and pigment diluents. Used for extracting oils and fats from various edible oils and spices such as soybeans, rice bran, and cottonseeds. In addition, n-hexane isomerization is one of the important processes for producing high octane gasoline blending components.

Trichloroethylene

Trichloroethylene

Trichloroethylene is a compound formed by replacing three hydrogen atoms in an ethylene molecule with chlorine. Difficult to dissolve in water, soluble in ethanol, ether, etc. Trichloroethylene is a flammable liquid that poses a risk of fire and explosion when exposed to open flames and high heat. Trichloroethylene has been used as an analgesic and metal degreaser, as an extractant, fungicide, refrigerant, and as a dry cleaning agent for clothes. This substance is composed of three elements: carbon, hydrogen, and oxygen. Colorless liquid with a smell similar to chloroform. Molecular formula C2-H-Cl3. Molecular weight 131.39. Relative density 1.4649 (20/4 ℃). Melting point -73 ℃. Boiling point 86.7 ℃. Flash point 32.22 ℃ (closed cup). The self ignition point is 420 ℃. The vapor density is 4.53. The vapor pressure is 13.33kPa (100mmHg at 32 ℃). The flammable limit of the mixture formed by steam and air is 8.0% to 10.5%.

Chlorinated benzene

Chlorinated benzene

Fluorobenzene

Fluorinated benzene is a chemical substance with the chemical formula C6H5F. It is thermally stable and does not decompose even when heated at 350 ° C and 400atm for 24 hours. But like benzene, it can undergo chlorination, nitration, and sulfonation reactions. This product is flammable and toxic.

Hydrogen peroxide

Hydrogen peroxide

Hydrogen peroxide, chemical formula H2O2. Pure hydrogen peroxide is a light blue viscous liquid that can be mixed with water in any proportion. It is a strong oxidant, and its aqueous solution is commonly known as hydrogen peroxide. It is a colorless and transparent liquid. Its aqueous solution is suitable for medical wound disinfection, environmental disinfection, and food disinfection. In general, it slowly decomposes into water and oxygen, but the decomposition rate is extremely slow. To accelerate its reaction rate, catalysts such as manganese dioxide can be added or short wave radiation can be used.

ammonia

Ammonia water, also known as ammonia water, is mainly composed of NH3 · H2O. It is an aqueous solution of ammonia, colorless, transparent, and has a pungent odor. The melting point of ammonia is 77.7 ℃, the boiling point is 33.5 ℃, and the density is 0.91g/cm ³. Ammonia is easily soluble in water and ethanol. Easy to evaporate, with some alkaline properties, ammonia water is produced by passing ammonia gas into water.
