Flammability, thermal stability, and phase change characteristics of several trialkylimidazolium saltsThe authors wish to thank the scientists at the Occupational Safety and Health Administration ? Salt Lake Technical Center for their measurement of the imidazolium flashpoints.The policy of the National Institute of Standards and Technology (NIST) is to use metric units of measurement in all its publications, and to provide statements of uncertainty for all original measurements. In this document however, data from organizations outside NIST are shown, which may include measurements in non-metric units or measurements without uncertainty statements.
