Document Summary

Distillation is a method used to separate two or more compounds. This is done by working on the differences in their boiling points. In this lab, both simple and fractional distillations will be observed and recorded. The extraction of compounds will then be observed using water soluble dyes to mark organic and aqueous layers. The apparatus was set up as described on page 18 of the lab manual, clamps were added to hold the apparatus in place. After setting up the apparatus, 50ml of a 50:50 mixture of 2-propanol and 1-butanol was added to the distillation flask using a long stem funnel. Boiling chips were added before turning on the heating devices and slowly distilling the solution. Temperatures were recorded as observed after every 1ml of distillate was collected until a total of 24ml of distillate had been collected. A fractionating column was added to the existing apparatus used in the simple distillation.
