Getting the temperature between 176°F and 212°F (boiling point of water) is a little tough, but doable. A lot of heat is lost to the atmosphere when using this very small equipment, so a thermometer placed in the distillation head is a pretty good indicator of the boiling point. 28 (Mean or Weighted MP) VP(mm Hg,25 deg C): 2. 15 degrees Kelvin (K). That is, the more carbons, the higher the temperature. But when the alcohol is added to a boiling liquid and then removed from the heat, 85 percent of the alcohol remains. 6 K. He suggested that the concentration of alcohol employed be such that it began boiling at 80 °Ré — that is, when it had expanded in volume by 8%. A boiling point elevation constant is an experimentally determined number that indicates the degree to which a change in a liquid's solute concentration affects its boiling point. Butanol is one of the group of “fusel alcohols” (from the German for “bad liquor”), which have more than two carbon atoms and have significant solubility in water. 67 estimate) = 0. As the altitude increases, the atmospheric pressure pushing down on water decreases, which allows the water to boil at lower temperatures.
