Web23 sep. 2024 · Acetonitrile is a common organic solvent. Acetonitrile-water is similar to methanol-water in rP-LIQUID chromatography and is often used as a mobile phase. It is obvious that acetonitrile, like methanol, is a polar solvent. Acetonitrile is generally considered to be miscible with water under any conditions. Many of the so-called …
Webother sectors as well. Since solvents which are insoluble in water exhibit a substantially constant flash-point irrespective of the concentration of the two-phase solvent-water mixture, only completely miscible and partially miscible solvents were selected.
