Energy demand

  • It is estimated that the current consumption of petroleum is at a rate 100.000 times faster than nature can replace it.

Alternatives:

  • Wind
  • Solar
  • Nuclear
  • Hydro
  • Biomass

Ionic Liquids + Metal Catalysts

  • Ionic liquids are low melting organic salts (<100 0C) that potentially comprise wide application due to their fascinating properties and have emerged as promising “green” replacement for volatile organic solvents.
  • Like the conventional salts, ionic liquids are mainly composed of ions which are positively and negatively charge.
  • The most attractive properties of ILs are their chemical and thermal stability, non-flammability, and negligible vapour pressure.

Conclusion

  • Synthesis of RTILs (room temperature ionic liquids).
  • High HMF yields without any side products.
  • Around 45 % HMF yield without the use of catalyst.
  • One of the highest (96%) HMF yields in the literature.
  • High reaction rate.
