This experiment combines techniques learned in previous experiments recrystallization MP with a new technique. The separation is based on the acidbase properties of the substances in the mixture. To understand the principles behind the separation it is essential that you understand the acidbase chemistry involved and why each chemical species is so luble or insoluble in each.

Benzoic acid mp 122-123 4-Chloroaniline mp 68-71 Naphthalene mp 80-82 2 The 4-chloroaniline is separated first by extraction with hydrochloric acid. Since no phenolic compound is present in this mixture two extractions with base solution are not required. Thus the benzoic acid could be separated from the neutral compound by extraction with either aqueous sodium bicarbonate or aqueous.
