Richard Duong Chem 262L Joseph Sokol 18 February 2010 Experiment 1-Separation of Components from a Mixture O R OH + R O O OH + H 2 O O R O + R O OH + HSO 4 H 2 SO 4 Purpose : to perform a solvent-solvent extraction to separate an organic compound from a mixture in order to remove any impurities that the organic compound may have, leaving its pure form. Procedure : 1.001g of an unknown compound, labeled ‘2,’ was massed and placed into a 125mL Erlenmeyer flask. 15mL of diethyl ether and 15mL of 5% NaOH were also added to the same flask. All the contents of the Erlenmeyer flask were poured into a separatory funnel. The Erlenmeyer flask was rinsed with 10mL of ether and also added to the separatory funnel. The separatory funnel was first vented by inverting the funnel and opening the stopcock. Then, the contents in the separatory funnel were swirled together for two minutes, occasionally vented. The separatory funnel was then left to sit so that two layers formed.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
