Comparison of Two Fat Extraction Methods
In this procedure, ether is often used as a solvent due to its low boiling point, relatively non-toxic nature (when compared to chloroform or methanol), and of course because it is quite non-polar. When talking about ether, two kinds are used in lipid extraction: anhydrous diethyl ether CH3CH2OCH2CH3 and petroleum ether, which is a mixture of pentane (CH3CH2CH2CH2CH3) and hexane
