Abstract
Reports a study that provides advanced knowledge on the thermal and combustion hazard profiles of ionic liquids based on an original multiscale combined experimental approach. Researchers implemented experimental tools implemented to (a) obtain actual measurements of theoretical heats of combustion of imidazolium-based and phosphonium-based ionic liquids by use of a bomb calorimeter; (b) provide access to fundamental flammability properties of these chemicals through the use of Pyrolysis Combustion Flow Calorimeter; and (c) determine actual behaviour of ionic liquids in fire conditions, from learnings obtained by a series of combustion tests performed on 12 ionic liquids by use of the INERIS Fire Propagation Apparatus.
Results produced so far confirm that the combustibility potential as well as the fire behavior must be assessed on a case by case approach and is often dictated by the chemical structure of ionic liquids. The study also illustrates how the data obtained by our innovative procedure allow for consistent fire safety engineering studies serving the green use of ionic liquids in a contextual way.
