General Description

3-Hexamethyleneiminopropionitrile is a chemical compound with the molecular formula C9H17N2. It is a widely used industrial chemical, commonly employed as a stabilizer in the production of rubber and plastics. 3-HEXAMETHYLENEIMINOPROPIONITRILE is a white crystalline solid at room temperature, and it has a slightly bitter taste. It is known to be a skin and eye irritant, and exposure to the compound should be limited and conducted in a well-ventilated area. Additionally, 3-hexamethyleneiminopropionitrile is considered to be harmful if swallowed, inhaled, or absorbed through the skin, and protective equipment such as gloves and goggles should be used when handling it.

Nitrile-functionalized azepanium ionic liquids: Synthesis characterization and thermophysical properties

The synthesis of nitrile-functionalized azepanium ionic liquids such as 1-butyl-1-(2-cyano-ethyl)-azepanium bromide, [C4CNAzp][Br], 1-butyl-1-(2-cyano-ethyl)azepanium trifluoroacetate, [C4CNAzp][TFA], 1-butyl-1-(2-cyano-ethyl)-azepanium methanesulfonate [C4CNAzp][CH3SO3], 1-butyl-1-(2-cyano-ethyl)azepanium trifluoromethanesulfonate [C4CNAzp][CF3SO3], 1-butyl-1-(2-cyano-ethyl)azepaniummethanesulfate[C4CNAzp][CH3SO4],1-butyl-1-(2-cyano-ethyl) azepanium p-toluenesulfonate [C4CNAzp][PTS] were performed. The synthesis of ionic liquids was performed in three steps. 1H, 13C and CHNS elemental analysis were used to characterize the synthesized ionic liquids. The thermal stability, melting point and glass transition temperature of the ionic liquids were determined. The nitrile-functionalized ionic liquids showed good thermal stability.
