Is trimyristin responsible for the odor of nutmeg
What is responsible for the smell and taste of nutmeg?
Essential oils. The essential oil of M. fragrans is obtained by the steam distillation of ground nutmeg and is used heavily in the perfumery and pharmaceutical industries. The oil is colorless or light yellow and smells and tastes of nutmeg.
Is trimyristin a nutmeg?
Nutmeg spice comes from the seeds of the Myristica fragrans tree in the East Indies. Trimyristin is found in the fixed oil of nutmeg. The fixed oil comprises approximately 24-40% of the nutmeg seed. Trimyristin comprises 73% of the fixed oil.
How is trimyristin extraction from nutmeg?
Isolation from nutmeg
Trimyristin makes up between 20-25% of the overall mass of dried, ground nutmeg. Separation is generally carried out by steam distillation and purification uses extraction from ether followed by distillation or rotary evaporation to remove the volatile solvent.
What is the theoretical yield of 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.
What is trimyristin used for?
Presently, the main use of trimyristin is for research and development as a laboratory reagent.
What is the chemical name for nutmeg?
Myristicin
Myristicin is a naturally occurring compound found in common herbs and spices, the most well known being nutmeg.
What 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.
What is the boiling point of trimyristin?
What is the structural difference between saturated monounsaturated and polyunsaturated fats of which kind is trimyristin?
Of which kind is trimyristin? Saturated fats have no carbon-carbon double bonds. 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.

What does refluxing a reaction mean in organic chemistry lab quizlet?
STUDY. Chemists have developed a simple method of heating a reaction mixture for extended periods without loss of reagents. This. process is called refluxing, which simply means. boiling a solution while continually condensing the vapor by cooling it and returning the liquid to the reaction flask.
What physical test can you do to check whether you have truly isolated trimyristin and not myristic acid?
A simple solubility test in an aqueous solution of NaOH could be used to distinguish between trimyristin and myristic acid.
Is trimyristin hazardous?
Material may be irritating to the mucous membranes and upper respiratory tract. May be harmful by inhalation, ingestion, or skin absorption. May cause eye, skin, or respiratory system irritation.
What are the melting points of trimyristin and of myristic acid?
The dried sample also had the melting point taken and was recorded at 54 °C. The literature gives a melting point value of 54.4 °C for myristic acid, so the product of hydrolysis and acid addition can be identified as such.
What is the chemical structure of trimyristin?

Is acetone considered a hazardous material?
While it is a widely used product, and is even made in our bodies, acetone is considered a hazardous waste material and needs to be handled and disposed of properly. The potential negative health effects are skin, eye and lung irritation.
What organs are targeted by the toxic effects of acetone?
Causes damage to the following organs: central nervous system (CNS). May cause damage to the following organs: kidneys, the reproductive system, liver, skin. Other Toxic Effects on Humans: Hazardous in case of skin contact (irritant), of ingestion, of inhalation.
What environmental concerns are present with acetone release?
Acetone is mainly emitted to air. It can move from the atmosphere into the water and soil by rain and snow, and it can quickly volatilise back into the air. Acetone is also capable of moving into the groundwater from spills or landfills, where it can be degraded within days.
Can acetone fumes harm?
Breathing moderate to high amounts of acetone for a short amount of time can irritate your nose, throat, lungs and eyes. It can also cause headaches, dizziness, confusion, a faster pulse, nausea, vomiting, effects on the blood, passing out and possible coma, and a shorter menstrual cycle in women.
