Solvents are liquid, gas, or solid chemicals that dissolve, extract, or suspend other substances. The most common and “universal” solvent is water, which dissolves more substances than any other.
Solvents are often categorized as polar or nonpolar, a factor of the solvent’s structure and charge that determines the types of substances that it can dissolve. Polar solvents have a “positive” and a “negative” charge at different places in their structures and will dissolve other polar substances. Water is a polar solvent; other polar solvents include acetone, acetonitrile, dimethylformamide (DMF), dimelthylsulfoxide (DMSO), ethanol, isopropanol, and methanol.
Nonpolar solvents include alkanes (pentane, hexane, and heptane) and aromatics (benzene, toluene, and xylene). Other common nonpolar solvents include acetic acid, chloroform, diethyl ether, ethyl acetate, methylene chloride, and pyridine. Nonpolar organic solvents are used as spot removers, paint thinners, nail polish removers, glue solvents, and in perfumes and detergents.
Solvents are used extensively as a medium for chemical reactions and analytical separations and are available in various purity grades and packaging options. They are also essential for manufacturing cosmetics, pharmaceuticals, personal care items, textiles, paints, pesticides, and many other products.
Long-term exposure to some solvents can be hazardous to worker health, however. Chloroform and benzene, commonly found in gasoline, are carcinogenic in addition to other solvents. Solvents can also damage the liver, kidneys, nervous system, or the brain. Chronic solvent-induced encephalopathy (CSE) is a known condition and occupational exposure to organic solvents is associated with alcoholism, cataracts, and the loss of hearing and color vision.
