Initial boiling point 初留点
WebbInitial boiling point. For a single component liquid without any impurities, the boiling occurs at constant temperature for a given pressure value. This temperature is known as boiling point of that liquid and it depends only on the pressure. A pure liquid component, can be completely vaporized at a single temperature and pressure point.
