Recrystallization

Purpose: The purpose of this experiment was to isolate trimyristin from nutmeg tree by performing a simple solid- eloquent extraction, to purify the impure production from the nutmeg by recrystallization and to assess the purity of the resulting square by development melting points. Procedures: We began by taking genius walloping nutmeg in its solid form and grinded it up using a mortar and pestle for five minutes. The nutmeg in its solid form was brown in affectation and smelled mellisonant like cinnomin. Before crushing the nutmeg weighed 3.419 grams. We weighed the resulting pulverize to be 3.228 grams. We then transferred the powder nutmeg into a 50 ml round bottom flask and added 15 ml of dichloromethane. We pose our flask in to a exemplification high temperature wane apparatus and gently refluxed the diversity. We waited until we saw the first flatten of liquified in the apparatus and heated for 15 minutes. later the mixture was heated, there was soli d on the bottom and liquid on the top of the flask. The set up was let calm to way of life temperature. Next, we decanted the mixture in to a loot 100 ml beaker. We rinsed the remaining solid with 10 ml of DCM and swirled the mixture. The mixture was decanted once more in to the same beaker. Next, we added boiling chips to the liquid and evaporated the solvent over the calefactory plates under the hood.

later on the solvent was evaporated and the flask was cooled, we employ a spatula to remove a small amount of the bleak product and took its melting point. We opinionated the melting point tend of the stra in to be 43.0-46.0 degrees Celcius.The bump! y product was yellow sullen when it was warm and orange in color when cooled and sticky. We then recrystallized our exemplar using 5 ml of warm acetone that was heated on a hot plate under a hood. The warm acetone was poured in to the beaker with our crude sample and swirled. The beaker with our sample was then placed in to an ice bath to cool and recrystallize. As the sample cooled, crystals began to plant in our sample.
