Reflux of Nutmeg

The purpose of this experiment was to extract Trimyristin (C45H86O6 ) from ground nutmeg powder. Trimyristin is a white to yellowish-gray solid that is insoluble in water, but soluble in ether. Trimyrisin is found naturally in many vegetable fats and oils. Its synthesis was done using reflux as shown in the diagram on page 3. Allow the crystals to dry for 1 week then, weigh it, take a MP, and calculate the % yield. * Assemble the apparatus for reflux using the diagram (see figure 1), place boiling chips or a stirring bar in the bottom of the flask. * Weigh 2grams of finely ground nutmeg and combine with 10ml of diethyl ether in a 50ml round bottom flask. * Place a heating mantle under the round bottom, turned on and the heat was slowly adjusted until the mixture starts to boil for 45minutes, then let cool to room temperature by sitting it on the lab bench. * Pour a little ether over the nutmeg residue on the filter paper so that any Diethyl ethanol traces clinging to it is washed down and mixed with the filtered liquid underneath. * Filter the mixture by gravity filtration, washing the nutmeg residue with 10ml of diethyl ether. Evaporate the Ether from the filtrate * Recrystallize the product from ethanol. Filter using a Buchner funnel and wash them with cold water as shown in the diagram (see figure 2). * Let the crystals dry for one week, record the weight and take a sample and put into a glass capillary tube to obtain a melting point using the Melt-Temp machine. * Since volatile inflammable substances (ether, ethanol) and heat are used in this procedure, be very careful while conducting this experiment.
