CHEM 223 Acid-Base Extraction Theory

Introduction Acid base extraction is another type of way to separate compounds. It allows acids and bases to be separated from neutral compounds. The differences in the solubility of some functional groups allow us to distinguish the compounds.

Once you understand these changes in solubility, fill in A table like the following to predict the solubility of the four specific compounds shown earlier. This will be included in your report for this virtual lab day, along with the actual structure of any ionic form of the four compounds.

Discussion: The functional groups are the major reason for the solubility of each compound. The OH groups are insoluble in most things sense the cholesterol is non polar. Acetophenone is soluble in acids due to the amine group. 4-t-butylphenol is soluble in stronger bases. And Benzoic acid soluble in bases but not in acid or water, To further exemplify your understanding of acid-base extraction, fill in the following generic chart that shows a general extraction scheme. You may abbreviate with CA, P, A, and NC for carboxylic acid, phenol, amine, and neutral compound, resp.

Discussion The neutral compounds and atoms without a charge will not be soluble in acid or base because they have to dissociate before they are able to dissolve. But they will dissolve in ethyl acetate. The rest of the compound will dissolve.

Conclusion An acid-base reaction is a good way to separate organic compounds. In this lab we predict what compound will dissolve in each solvent based on properties but we did not test them. We also created a chart predicting the dissociation patterns....
