How to perform solvent extraction of a solid Suppose I have a solid compound from which I want to extract a target chemical I know is soluble in acetone.  So I crush and mix the compound in acetone, dissolving the target and suspending the detritus.


What are methods for filtering the detritus from the solution? I have frequently seen coffee filters used for this purpose.  Are commercial coffee filters considered "lab-grade?"  Or, suppose that the target chemical has some affinity for cellulose, what alternatives exist for suspension filtration?
Now, having the target chemical in solution I assume it is easiest to extract it by evaporating the acetone.  Is there a process for this that doesn't leave any of the target stuck to the glass or whatever was containing the solution?

The method that comes to mind for this task is a Soxhlet extraction. Commercial coffee filters are not "lab-grade." Soxhlet extraction thimbles are available in cellulose.

Yes - rotary evaporation, in conjunction with Soxhlet extraction.
