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.
