Why dichloromethane were used as a solvent in liquid-liquid extraction?

chlorine atoms have high electronegativity, which will distort the electron cloud of the molecule.
DCM is highly polar, and it is also an organic molecule.
thus it is a good solvent for other organic molecules, very often used in non-biological organic synthesis.

What is PERL acronym for?
Practical Extraction and Report Language. It is a programming language used by websites and many other things.
What does balsa cement mean?
It's a fast-setting solvent based glue used to put things made of balsa together.
How is petroleum used by humans for energy?
through extraction from pockets deep in the earth and the processing and refinement of crude oil ! but mostly in a combustable engine system (generators) !
What is the term plait point?
A plait point is a term used in liquid-liquid extraction. It is the point where all three phases (in a ternary diagram) are partially soluble in each other. (excuse me if this is wrong)
What is a heat source in ac and heating?
That will all depend of the type of system being used. Heat in an A/C is generated by the compressor and the heat extracted from the air it is conditioning. Heat in a heater can come from fire (gas, oil, wood) or geothermic extraction from water under ground.
For extraction of lipids from seaweeds which is the best method?
Dichloromethane can be used for extraction of lipids from seaweeds. There are still many ongoing studies as the best method for lipid extraction but no standards have been put into place.
What is the commercial value of kerosene?
- It is used as a jet fuel - It is used as a solvent in solvent extraction of metals, etc.
What chemical processes are used to create fragrant oils?
Two methods are used: solvent extraction or water vapor extraction.
What is the boiling point of DCM?
Dichloromethane is an organic compound which has a sweet aroma and is used widely as a solvent. The formula is CH2CI2 and is colorless. This solvent has a boiling point of 103.3 degrees F.
Why repeated extraction is better than solvent extraction?
Because you are providing a greater surface area of contact between the aqueous layer and organic layer
What method is used for separating curcumin from turmeric?
Curcumin is separated by solvent extraction.
In liquid liquid extraction what factors you consider to choose select the proper solvent as an example consider the extraction of benzoic acid from water?
1-structure of molecule (which has to be separated), 2-polarity of molecule and 3-polarity of solvent used. In this case benzene or toluene as a solvent may be selected.
Why can't alcohol be substituted for ether as an extraction solvent?
No, alcohol is a polar solvent and extracts only polar components while ether is used to extract the non polar constituents.
What happens if more polar solvent used with trimyristin in extraction process?
Trimyristin is primarily nonpolar, dissolving it in a polar solvent wouldn't effectively separate it from the mixture. Good luck with orgo lab.
Why ether is use as an extraction solvent?
For extraction of organic solvents generally diethylether is used because organic substances are generally soluble in ether and ether has got a low boiling point making its removal after the extraction very easy.
What purpose does a 1 cm layer of anhydrous sodium sulfate in the apex of the funnel serve while transferring the dichloromethane extract into the round bottom flask.?
Anhydrous sodium sulfate is used as a drying agent to remove microscopic amounts of dissolved water in a solvent. It works by chemically reacting with the water by forming its hydrate, which is insoluble preferably in the solvent in this case dichloromethane. This allows one to filter off the crystals containing the water that would otherwise have remained dissolved in the dcm.
