Types of organic solvents There are many types of organic solvents, which can be divided into 10 categories according to their chemical structure: ①Aromatic hydrocarbons: benzene, toluene, xylene, etc.; ②Aliphatic 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: ethyl ether, propylene oxide, etc.; ⑦ esters: methyl acetate, ethyl acetate, propyl acetate, etc.; ⑧ ketones: acetone, methyl butanone, methyl isobutyl ketone, etc.; ⑨ glycol derivative Substances: ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monobutyl ether, etc.; ⑩ Others: acetonitrile, pyridine, phenol, etc.
From the category point of view, organic solvents are a large class of organic compounds widely used in life and production. The molecular weight is not large and it is liquid at room temperature. Organic solvents include many types of substances, such as paraffins, alkenes, alcohols, aldehydes, amines, esters, ethers, ketones, aromatic hydrocarbons, hydrogenated hydrocarbons, terpene olefins, halogenated hydrocarbons, heterocyclic compounds, nitrogen-containing compounds and sulfur-containing compounds, etc. And so on, most of them are toxic to the human body.
