Trimystin

Trimyristin is found naturally in many ve instituteable fats and oils. Trimyristin is a white to yellowish-gray solid that is in water-soluble in water, but soluble in ethanol, benzene, cloroform, dichloromethane, and ether. It is a saturated fat which is the triglyceride of myristic acid. The purpose of this science lab was to extract the fat trimyristin from the spice nutmeg by manipulation of organic solvent, methylene chloride. Nutmeg comes from an East Indian tree. The seeds be rich compounds known as triglycerides, which are made up of glycerol esterfied to three fatty acids.




Five grams of nutmeg was weighed and coalesce with 50ml of mthylene chloride in a 100ml about bottom flask. A ruflux apparatus was set up and the categorization was brought to a boil in a steam bath. The mixture was refluxed to avoid evaporation composition it boiled for 30 minutes. After 30 minutes the mixture was cooled and then filtered through fluted filter report card into a 250ml round bottom flask. The methyene chloride dissolved the trimystrin and would pass through the filter paper leaving the other nutmeg solids behind. The solution was then distilled to get rid of the methlyene chloride and isolate the trimyristin. Methlyene chloride was a good solvent in this case because its boiling floor is 40 degrees C and leave boil off before the trimyristin which has a boiling bakshis of 56-57 degrees C.



Finally acetone was added to wash the crystals and the solution was vacuum filtered. This butt was repeated and the trimyristin was collected.


Results:
Experimental yield of trimyristin= .64g
Experimental melting point of trimyristin= 59 degrees C
Percentage yield = experimental-truex100
True


Dicussion: The extraction of trimystrin go away white crystals resembling a powder. Its melting point was 56 degrees C which was exactly the recorded value. However, given that 20 to 25 part of ground nutmeg is trimyristin by mass this experiment gave a low yield, about 12%...If you want to get a full essay, order it on our website: Orderessay
