What is the critical temperature for diesel fuel?

The critical temperature for diesel fuel typically ranges between 300 °C and 400 °C (approximately 572 °F to 752 °F), depending on its specific composition. At this temperature, diesel fuel transitions from a liquid to a supercritical state, where it exhibits unique properties that differ from both liquid and gas phases. This critical point is important for processes like supercritical fluid extraction and combustion efficiency in advanced engine designs.
