Solvent refers to a substance that can dissolve other solids, liquids, gases, and other solutes. The most common solvent in our daily lives is water. Generally, the solvent has a low boiling point and is easy to volatilize, and the solvent cannot produce a chemical reaction to the solute. Solvents are generally colorless and transparent liquids with unique odors. Solvents play a very important role in adhesives. Organic solvents are a large class of organic compounds that are widely used in life and production. They have a small molecular weight and are liquid at room temperature. Organic solvents include many types of substances, such as paraffin, 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. Etc. Most of them are toxic to the human body. Solvents are generally found in paints, adhesives, lacquers, and cleaners. Commonly used organic solvents include DMF, cyclohexanone, acetonitrile, acetic acid, methyl acetate, ethyl acetate, isopropanol, vinyl acetate, cyclohexane, n-hexane, n-heptane, etc. Organic solvents are a class of organic compounds that can dissolve some water-insoluble substances (such as grease, wax, resin, rubber, dyes, etc.). Its characteristic is that it is liquid at room temperature and pressure. It has greater volatility. In dissolution During the process, the properties of the solute and solvent are unchanged. 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.; ⑤Alcohols: methanol, ethanol, isopropanol, etc.; ⑥Ethers: ether, propylene oxide, etc.; ⑦Esters: methyl acetate, ethyl acetate, propyl acetate, etc.; ⑧ Ketones: acetone, methyl butanone, methyl isobutyl ketone, etc.; ⑨Diol derivatives: ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monobutyl ether, etc.; ⑩Others: acetonitrile, pyridine, phenol, etc. Read More about: Chemical Flow Meter Guide
