Organic solvents are a large class of organic compounds widely used in daily life and production, with small molecular weights. They exist in coatings, adhesives, paints, and cleaning agents. Organic solvents such as styrene, perchloroethylene, trichloroethylene, ethylene glycol ether, and triethanolamine are often used. Organic solvents can dissolve some insoluble organic compounds (such as fats, waxes, resins, rubber, dyes, etc.), which are characterized by being liquid at room temperature and pressure and having high volatility. During the dissolution process, the properties of both the solute and solvent remain unchanged. Solvents are divided into organic solvents and inorganic solvents based on their chemical composition.

There are many types of organic solvents, which can be divided into 10 categories based on their chemical structures: ① aromatic hydrocarbons: benzene, toluene, xylene, etc.; ② Fatty hydrocarbons: pentane, hexane, octane, etc.; ③ Alicyclic hydrocarbons: cyclohexane, cyclohexanone, toluene cyclohexanone, etc.; ④ Halogenated hydrocarbons: chlorobenzene, dichlorobenzene, dichloromethane, etc.; ⑤ Alcohols: methanol, ethanol, isopropanol, etc.; ⑥ Ethers: ether, epichlorohydrin, etc. ⑦ Esters: methyl acetate, ethyl acetate, propyl acetate, etc.; ⑧ Ketones: acetone, methyl butanone, methyl isobutanone, etc.; ⑨ Glycol derivatives: ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monobutyl ether, etc Other: acetonitrile, pyridine, phenol, etc.
