Can liquid paraffin oil be used as the non-polar solvent in an acid-base extraction?

I havn't been able to find any info about the dielectric constant of liquid paraffin oil. Therefore I have little knowledge about the usefulness of the oil in these kinds of processes. In the extraction the paraffin oil would be used for removing the non-polar organic waste from a HCl-water solution and should contain all useless organic material.Can liquid paraffin oil be used as the non-polar solvent in an acid-base extraction?
While somewhat awkward in terms of what is normally done, it would work. The difference is in a normal lab question, the objective is to isolate an organic compound from inorganic or very polar organic compounds and isolate the organic compound. In the case of using a liquid paraffin as in paraffin wax, the high mw of the paraffin would make isolation of the organic matter more difficult.





If you are using paraffin in the ';Chemistry old-fashioned term for alkane';, then sure and it is only the form of your question that leads to confusion.
