How to Find the Best Cannabis Extraction Solvents

Supercritical CO 2 may be one of the most common solvents in the industry but it is also a fairly limited solvent CO 2 is a fairly weak non-polar solvent meaning that it will capture non-polar components like waxes and lipids along with cannabinoids The end result is a cloudy mixture that is undesirable to most consumers As such most CO

Is acetone a polar or nonpolar solvent?

Usually Most organic solvents (hydrocarbons) are non-polar and so are immiscible with water and so form layers (like oil and water) Compounds like diethyl ether (ether) and ethyl acetate (EtOAc) are less dense than water and so appear in the top layer when mixed with water
