Distillation. Laboratory display of distillation: 1: A source of heat 2: Still pot 3: Still head 4: Thermometer/Boiling point temperature 5: Condenser 6: Cooling water in 7: Cooling water out 8: Distillate/receiving flask 9: Vacuum/gas inlet 10: Still receiver 11: Heat control 12: Stirrer speed control 13: Stirrer/heat plate 14: Heating (Oil/sand) bath 15: Stirring means e.g.


(shown), boiling chips or mechanical stirrer 16: Cooling bath.[1] History[edit] Clear evidence of the distillation of alcohol comes from the School of Salerno in the 12th century.[2][5] Fractional distillation was developed by Tadeo Alderotti in the 13th century.[6] A retort. The Distillation Experiment. Introduction to Distillation. Distillation is based on the fact that the vapour of a boiling mixture will be richer in the components that have lower boiling points. Therefore, when this vapour is cooled and condensed, the condensate will contain more volatile components.

At the same time, the original mixture will contain more of the less volatile material. Distillation.swf (application/x-shockwave-flash Object) ChemEngcolumn.swf (application/x-shockwave-flash Object) Molecular Workbench Home Page. Energy in a High-Tech World.
