WebPolar 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), isopropanol, and methanol. WebAcetonitrile (CH 3 CN), CAS 75-05-8, also known as methyl cyanide or cyanomethane, is the simplest organic nitrile. Produced mainly as a byproduct of manufacturing acrylonitrile, acetonitrile is a colorless liquid with an ether-like odor. 1 – 30of75 Results 1
