trimyristin remains undissolved then add an extra 1 mL portion of ethanol and rehea the solid is totally dissolved remove it from the hot water bath and allow it to slowly cool to room temperature in a beaker or cork ring You may wish to scratch the bottom of the flask LIGHTLY with your spatula or stir rod At this time some trimyristin solid should be seen After the flask has cooled to room temperature place it in an ice bath to aid solidification of the trimyristin Collect the solid using vacuum filtration See Page 23 If your solid contains impurities yellowish pigment you can rinse it with small amount drops of chilled ethanol If you do be sparing as the trimyristin will wash away some in the cold solvent Store the solid open to the air in your drawer Collect the weight of pure solid next week During week 2 1 Record the dry weight of the pure trimyristin 2 Obtain an IR of the Trimyristin Data Calculation 1 Wt of nutmeg grams Wt of extracted crude trimyristin recovered crude trimyristin 2 3 4 5 6 7 grams grams of crude trimyristin grams of nutmeg Wt of pure trimyristin after recrystallization recovered from recrystallization recovered pure trimyristin IR spectrum and Melting Point x 100 grams of pure trimyristin grams of crude trimyristin x 100 grams of pure trimyristin grams of nutmeg x 100 Note Dichloromethane is a very good extraction solvent and can be used in this experiment however ethyl acetate is used to perform this experiment due to its non toxicity and higher boiling point Reference p 117 extraction p 120 W W
