In the Laboratory

Abstract
As a laboratory exercise the constitents of a mixture of 2,2,4-trimethylpentane, methoxybenzene and benzoic acid are separated by a combination of extraction and distillation. The crude products are further purified by recrystallization for the solid and redistillation for the liquids. Three important laboratory techniques are thus taught in two 4h laboratory periods.
