WebQuestion: Exercise \#4: A liquid mixture containing 0.3 mole fraction methanol and 0.7 mole fraction water is fed to an intermediate point in a continuous distillation column. The distillate is 0.97 mole fraction alcohol, and the bottoms is 0.08 mole fraction alcohol. The reflux ratio is 3 , and the feed enters at its boiling point. Web18 okt. 2007 · (1) If the boiling point is so indefinite, how can standard thermometers be made? A great irony: the result that water does not always boil at 100°C was established by means of thermometers which were calibrated on the assumption that it does boil at 100°C. This apparent nonsense is actually not as bad as it sounds. Read more.

WebBoiling points are reported at a pressure of 760 mm Hg unless otherwise stated. Where the mixture separates into layers, values are shown for upper ( U) and lower ( L) layers. The … Web7 apr. 2024 · There is an added inductive effect $ \left( { + I} \right) $ which results in higher density of negative charge on the oxygen residue. This is why the water has a higher … Methanol is primarily converted to formaldehyde, which is widely used in many areas, especially polymers. The conversion entails oxidation: Acetic acid can be produced from methanol. Methanol and isobutene are combined to give methyl tert-butyl ether (MTBE). MTBE is a major octane booster in gasoline. brogan donovan reporting
