CONTEXT 

Imidazolium-based salts and ionic liquids are used in the pharmaceutical and chemical industries, electronics and composite materials. Despite this high added value, their production process and end-of-life remain problematic because they do not meet the requirements of sustainable development and REACh regulations. Thus, new ecotechnologies must be developed: (i) to produce them in an eco-responsible way from renewable carbonaceous materials and (ii) to recycle them at the end of their life.

DESCRIPTION

To address this challenge, researchers at the ICMuB have designed an eco-innovative process to produce ionic compounds using up to 90% renewable carbonaceous materials. Their work continued with the addition of another new recycling process, which uses only electrons and no other energy or material input. These two eco-technologies thus allow to reduce the cost of the ionic compounds as well as the environmental impact of their life cycle. There are many applications for these eco-designed ionic compounds, such as: - organocatalysts in the synthesis of biodiesel or solvents for non-hazardous and non-flammable paints; - extraction solvents alternative to conventional ones because they are non-VOC and non-flammable, thus without ATEX risk in industry; - compounds for capturing, storing and transporting of CO2 at room temperature, by using a very energy-efficient process than those currently in use.

 

COMPETITIVE ADVANTAGES

  • Technology patented and double award-winning for its high environmental performance
  • Non-flammable, non-VOC & non-toxic solvents
  • Products recyclable at the end-of-life
  • Compounds biosourced up to 90%
  • Raw materials from sugar resources produced in France

 

MARKETS & APPLICATIONS

  • Chemical industry: production of ionic liquids, biosourced solvents, organocatalysts…
  • Electronics: production of electrolytes for batteries, fuel cells or solar panels
  • Pharmaceutical industry: production of oxazolidinones (synthesis intermediates)
  • Environment: treatment of gaseous effluents (selective capture and transport of CO2)
