Thermal Reaction of l-Butyl-3-Methylimidazolium Nitrate Ionic Liquids via Copper Catalyzer

摘要

Ionic liquids (ILs) have numerous advantages of physical properties, such as low vapor pressure, high conductivity, high thermal stability, non- toxicity, and low volatility. In industrial applications, ILs can feasibly substitute for volatile organic compounds, because of their low volatility characteristics, to retard the risk of escape and labor inhalation. Recent studies showed the corrosion properties of metals in ILs, which may cause change of thermal properties. We analyzed the thermal safety parameters for the copper catalytic reaction in l-butyl-3-methylimidazolium ([Bmim][N03]). We systematically analyzed in-depth the catalytic reaction and thermal hazards characteristics of copper in [Bmim][N03]. We employed differential scanning calorimetry to acquire the thermokinetic parameters, and subsequently predicted catalytic reaction progress under pseudo adiabatic environments, which was ultimately verified by vent sizing package.
