Acid Base Extraction


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......
