What is the purpose of isolation of trimyristin from nutmeg?
The purpose of this experiment was to illustrate the process of obtaining a pure organic compound from a natural source. The subfield of organic chemistry that deals with isolating and studying chemicals found in nature is natural products chemistry.
What is the theoretical yield when isolating trimyristin from nutmeg?
In the chemical equation of hydrolysis one molecule of trimyristin should yield 3 molecules of myristic acid. 58 mg of trimyristin was consumed in the reaction. The theoretical yield would be 55 mg of myristic acid and 41mg of product was collected.
Why was it necessary to remove the solvent when isolating the trimyristin?
The trimyristin has to be soluble in the solvent to get extracted from the nutmeg. Trimyristin is more soluble in ether than in acetone. with diethyl ether gave an oil after removal of the solvent, and this oil was difficult to crystallize.
How do you isolate trimyristin?
Extraction of Trimyristin: Add 2 g of nutmeg to a 25-mL or 50-mL round- bottomed flask, followed by 10 mL of dichloromethane. Add a boiling chip and fit the round-bottom flask with a reflux condenser. Gently heat the mixture for 30 minutes.

What type of functional groups are present in trimyristin?
Trimyristin is a triglyceride obtained by formal acylation of the three hydroxy groups of glycerol by myristic (tetradecanoic) acid. It is a triglyceride and a tetradecanoate ester.
Is trimyristin responsible for the odor of nutmeg?
One of the non-volatiles is trimyristin, a triglyceride which is partly responsible for the smell, the taste and texture of nutmeg.
Would water be a suitable solvent for extracting trimyristin from nutmeg explain your reasoning?
Water would not be suitable or extracting trimyrisitn from nutmeg because it is insoluble in water. Trimyristin in insoluble in water because it has a long chain of C-H groups which takes this compound nonpolar.
What can trimyristin be used for?
Presently, the main use of trimyristin is for research and development as a laboratory reagent.
Is trimyristin volatile?
Trimyristin makes up between 20-25% of the overall mass of dried, ground nutmeg. Separation is generally effected by steam distillation and purification uses extraction from ether followed by distillation or rotary evaporation to remove the volatile solvent.
Is trimyristin polar or nonpolar?
nonpolar
Trimyristin consists of long saturated hydrocarbon chains and it is relatively nonpolar. Thus using a relatively nonpolar solvent, trimyristin can be easily extracted by the concept of “like dissolves like”.
What is the melting point of trimyristin?
56°C to 57°C
