Document Summary

Simple distillation: a magnetic stirrer was set up, and a magnet was placed in a distillation flask. Fractional distillation: a magnetic stirrer was set up, and a magnet was placed in a distillation flask. The graduated cylinder was placed and clamped under the takeoff adapter, as the receiving flask: the variac was plugged in and turned on at around 85. The magnetic stirrer was plugged in and turned on at around 8: the temperature in the distillation head was recorded after every 2ml of distillate was collected, after distillation was completed, the final volume of distillate was recorded. Mass of the receiving flask with the distillate was measured on an electronic scale. Temperature in distillation head in c, over volume of distillation collected in ml, through simple distillation. 50:50 2-propanol and 1-butanol mixture solution is a colourless, non-viscous solution with alcoholic odour. First drop of distillate was at 83 c.
