why is methylene chloride used for extraction?

why is methylene chloride used for the extraction of essential oils?

Homework Answers

Answer #1

Essential oils are basically non-polar low chain terpenoid and non-terpenoid hydrocarbons which are responsible for its aroma. Thus we see that these are hydrocarbons and are non-polar in nature. Thus, when we do extraction of essential oils, we try to use some organic solvents in which the oil is soluble and after extraction, the solvent will be easy to evaporate so that the oil doesn't get degraded.

For this purpose, we have highly non-polar volatile solve methylene chloride or dichloromethane in which the oil is mixed well since it is non-polar and thus can be extracted easily and since the boiling point of methylene chloride is just 40 oC, thus it is really easy to get rid of it without degrading the oil.

1. Why is it necessary to keep pipettes separate; that is to use the H2O pipette only for H2O, and hexane pipette for hexane only? 2. . Extraction is a technique in which two immicible solvents are used to separate compounds, based on solubility. Give two examples of immicible solvent pairs that might be used for extraction. Cannot use the following as examples: Water and ethyl alcohol Water and diethyl ether Water and methylene chloride Water and hexane Hexane and...

Ethylene chloride, ClCH2CH2Cl (98.96 g/mol, density = 1.26 g/mL, bp = 83 °C), is an organic solvent with polarity similar to methylene chloride, and is also not miscible with water. a) If substituted for methylene chloride in this partition coefficient experiment, would ethylene chloride form the top or bottom layer? b) Provide an explanation, using appropriate data to support your answer. c) Despite the similarities, methylene chloride is superior to ethylene chloride as an extraction solvent. Why?
