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.
Is trimyristin responsible for nutmeg odor?
One of the non-volatiles is trimyristin, a triglyceride which is partly responsible for the smell, the taste and texture of nutmeg.
Is trimyristin flammable?

What is the main functional group that can be found in trimyristin?
the functional group present in trimyristin is a carboxylic acid group2. Pure trimyristin is a liquid at room temp3. The term lipid describes a category of organic compounds that are soluble in water.Why is trimyristin washed with cold acetone?
Ice-cold fresh acetone was poured over the recrystallized trimyristin while in the Büchner funnel to remove any remaining impurities and make the impurities enter into the filtrate (this was called “washing” the crystals).
What type of a carboxylic acid derivative is trimyristin?
Trimyristin belongs to the class of compounds known as fats or triglycerides. These are triesters of the trialcohol glycerol, and unbranched long-chain (14 or more carbons) carboxylic acids called fatty acids.
What is the melting point of trimyristin?
ColorWhiteMelting Point56°C to 57°CLinear Formula[CH3(CH2)12COOCH2]2CHOCO(CH2)12CH3Beilstein1718242Merck Index14,9724
Is trimyristin polyunsaturated?
Monounsaturated fats have a single carbon-carbon double bond in one or more of the carboxylic acid moieties. Polyunsaturated fats have two or more carbon-carbon double bond in the carboxylic acid moieties. Since trimyristin doesn’t have any double bonds it is a saturated fat.Is trimyristin soluble in acetone?
Trimyristin is not very soluble in acetone. That is why acetone was used as the crystallization solvent. The trimyristin has to be soluble in the solvent to get extracted from the nutmeg. Trimyristin is more soluble in ether than in acetone.
Is trimyristin an organic compound?This experiment illustrates the process of obtaining a pure organic compound from a natural source. Normally, because extracts from natural sources contain complex mixtures of compounds, isolation of a single pure compound requires long tedious separation and purification procedures.
Article first time published onWhat major products are formed when trimyristin is treated with NaOH in aqueous ethanol?
When trimyristin is refluxed with NaOH in aqueous ethanol and then acidified, the carboxylic acid, along with glycerol, is obtained.
How do you dispose of glycerol?

What is a good percent recovery for extraction?
Recovery criteria is (at least) 50% for many validation guidelines. However, there are many methods available in the literature in which analyte recovery was less than 50% but precision and accuracy were acceptable.
What Is percent recovery for extraction?
Percent recovery is the amount of a product obtained after its synthesis and purification. The percent recovery can be used to determine the efficiency of the synthesis reaction. This term is often used in organic chemistry to determine the yield obtained from recrystallization.
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.
Would water work as an extraction solvent for trimyristin?
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. Instead we will be using dichloromethane because trimyristin is soluble in that liquid.
Is it possible to extract trimyristin using cold diethyl ether?
Thus using a relatively nonpolar solvent, trimyristin can be easily extracted by the concept of “like dissolves like”. Diethyl ether is a relatively organic substance that can easily dissolve trimyristin more so than aqueous solvent.
Can trimyristin dissolve in water?
Trimyristin is an ester with the chemical formula C45H86O6. It is a saturated fat which is the triglyceride of myristic acid. Trimyristin is a white to yellowish-gray solid that is insoluble in water, but soluble in ethanol, acetone, benzene, chloroform, dichloromethane, ether, and TBME.
What is the physical state of pure trimyristin at room temperature?
Pure trimyristin is a liquid at room temperature. b. Nutmeg contains a complex mixture of organic compounds that are soluble in diethyl ether.
What is the boiling point of acetone?
Acetone is a colourless liquid with mildly pungent, somewhat aromatic odour. The melting point of acetone is -94.7°C (range: -94.6°C to – 95.6°C), the boiling point is 56.05°C (range: 56.05 to – 56.5°C).
Which solvent is required for the crystallization of Trimyristin?
Trimyristin is routinely extracted using hot ether or dichloromethane followed by crystallization from acetone.
Is Trimyristin soluble in methylene chloride?
Trimyristin is a white to yellowish-gray solid that is insoluble in water, but soluble in ethanol, benzene, chloroform, dichloromethane, and ether.
