Extraction of Trimyristin from NutmegPurposeTo extract trimyristin from nutmeg by performing a simple solid-liquid extraction and to purify product using recrystallizationChemicalsSubstanceStructureMelting PointBoiling PointDensityM.

Diethyl ether and acetone are polarThey will dissolve faster as they have a larger surface areaTrimyristin is ether. It has a lot of hydrogen attached to it making it saturated. The molecules pack together better than unsaturated molecules making it a solid at room temperatureBy gravity filtrationWater is not a good solvent choice
