We are researching for extracting phenolic acid from calamansi and lemon using soxhlet extraction, we are finding studies about how to remove solvent to the extract from soxhlet extraction.
@Rhovie Ann Soler, the extraction method you should choose is dependent on the amount of the extract (phenolic acid) you desire to obtain. Personally, I think the soxhlet extractor should be able to do the job. It operates with similar principle as distillation.
Hello Prince Dum Emmanuel , I mean after extraction, how do we separate the solvent and the extract (phenolic acid) in the flask after the soxhlet extraction?
Rhovie Ann Soler you can separate them on basis of the solubility difference using different solvents and precipitating main product.
Dear Rhovie, just in case that this technical question is still of interest to you: Normally you can just use a rotary evaporator to remove the solvent from your extract after Soxhlet extraction. You can also remove the solvent more slowly under vacuum using a cold trap while stirring with a magnetic stirring bar. This way you have a better control and can perhaps stop the evaporation procedure when a precipitate starts to form.
For more general information in this context please have a look at the following useful article:
