October 4, 2006 Thursday 1:30PM-6:00PM Extraction Purpose: The purpose of this lab experiment was to learn the process of extraction, a technique used to separate wanted materials from unwanted materials. Extraction specializes in the separation of compounds between two immiscible phases, which is also known as phase distribution. In extraction, we can selectively remove one or more components of a solid, liquid, or gaseous mixture into a separate phase. This particular lab requires the separation benzoic acid and naphthalene with the dissolution by diethyl ether. Main Reaction: Table of Data: Napthalene Recovered: .52g Melting point (range) of Napthalene: 69º-73º C Benzoic acid Recovered: Melting point (range) of benzoic acid: Procedure: 1. Get 2 g of benzoic acid and naphthalene and dissolve the mixture in 30ml of diethyl ether in an Erlenmeyer flask and then transfer the solution to the separatory funnel. 2.
