Additional information

The BASF study BRU 85.148 reports the boiling point of 2-ethyl-4-methylimidazole to be 272.79 °C at 1013.25 hPa. The Yaws' Handbook of Physical Properties for Hydrocarbons and Chemicals reports the boiling point to be 293.5 °C at ambient pressure. The GESTIS - Substance database reports the boiling point of 2-ethyl-4-methylimidazole to be between 272,8 °C and 295 °C at 1013 hPa and the Syracuse Research Coperation, Physical Properties Database reports the boiling point to be between 292 °C and 295 °C. The value which originates from the study was chosen as key value.
