Descrizione

Descrizione generale

N,N-Dimethylformamide (DMF) is the commonly employed solvent for chemical reactions. DMF is a useful solvent employed for the isolation of chlorophyll from plant tissues.[1] It is widely employed reagent in organic synthesis. It plays multiple roles in various reactions such as solvent, dehydrating agent, reducing agent as well as catalyst. It is a multipurpose building block for the synthesis of compounds containing O, -CO, -NMe₂, -CONMe₂, -Me, -CHO as functional groups.[2] Dielectric relaxation experiments on DMF have been conducted between 238.15K and 338.15K.[3] The thermophysical properties of the molecular interactions between DMF and the ionic liquids, ammonium salts and imidazolium salts have been studied.[4] The characteristics of solute-solvent interactions between ammonium nitrate and DMF have been investigated.[5]
