The purpose of this laboratory assignment was two-fold, first, we were to demonstrate the extraction of acids and bases, finally, determining what unknowns were present. Second, we were to extract caffeine from tea. These two assignment will be documented in two separate entities.
Introduction: Acid/base extraction involves carrying out simple acid/base reactions in
order to separate strong organic acids, weak organic acids neutral organic compounds
and basic organic substances. The procedure for this laboratory assignment are on the
following pages.
3) Separation of Carboxylic Acid, a Phenol and a Neutral Substance
The purpose of this acid/base extraction is to separate a mixture of equal parts of
benzoic acid(strong acid) and 2-naphthanol(weak base) and 1,4-dimethoxybenzene(neutral) by extracting from tert-butylmethyl ether(very volatile).The goal of this experiment was to identify the three components in the mixture and to determine the percent recovery of each from the mixture.
