Ethylene Glycol

Ethylene Glycol

Ethylene glycol (ethylene glycol) also known as "glycol", "1,2-ethylene glycol", referred to as EG. The chemical formula is (CH2OH)2, which is a simple diol. Ethylene glycol is a colorless, odorless, sweet-tasting liquid that is toxic to animals and lethal to humans at a dose of about 1.6 g/kg. Ethylene glycol can be miscible with water and acetone, but the solubility is small in ethers. Used as a solvent, antifreeze and synthetic polyester raw materials. Polyethylene glycol (PEG), a high polymer of ethylene glycol, is a phase transfer catalyst also used in cell fusion; its nitrate ester is an explosive.

Dimethylacetamide

Dimethylacetamide

Dimethylacetamide, also known as N, N-dimethylacetamide (chemical formula: CH3C (O) N (CH3) 2, abbreviated as DMAC or DMA). A commonly used non proton polar solvent. Colorless transparent liquid, flammable. Can be mixed with organic solvents such as water, alcohols, ethers, esters, benzene, trichloromethane, and aromatic compounds at will. Used in the production of drugs, synthetic resins, as well as solvents for polyacrylonitrile spinning and extraction distillation solvents for separating styrene from carbon eight fractions. Prepared by the reaction of dimethylamine and acetyl chloride.

Ethyl acetate

Also known as ethyl acetate, it is a colorless and transparent liquid with a fruity aroma. It is volatile, sensitive to air, and can absorb moisture. Moisture can slowly decompose it into an acidic reaction. It is a widely used fine chemical product with excellent solubility and fast drying properties. It is an important organic chemical raw material and industrial solvent, widely used in the production process of acetate fiber, ethyl fiber, chlorinated rubber, ethylene resin, acetate fiber resin, synthetic rubber, coatings, and paints.

Methyl tert butyl ether

Methyl tert butyl ether

It is a colorless, transparent, low viscosity volatile liquid with a special odor and an organic ether with an oxygen content of 18.2%. Commonly used as an anti knock agent in unleaded gasoline, it also has a wide range of applications in the chemical and biological fields.

cyclohexane

Cyclohexane is an organic compound with the chemical formula C6H12. It is a colorless liquid with a pungent odor, insoluble in water, and soluble in most organic solvents such as ethanol, ether, benzene, acetone, etc.

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%.
