This time average solubilized component i.e. component A will get separated from the solvent and will be collected into collection chamber A.Īgain the valve will reduce some more pressure. Here, the weakly solubilized component i.e. When this happens, some amount of liquid solvent gets converted to gas. Now, when this solvent + components mixture passes through the valve, it reduces a little pressure. But this time, in the extraction cell, we will have all the three compounds solubilized in the solvent mixture (carbon dioxide + acetic acid) The rest of the procedure will be the same. Let’s consider we have to extract 3 components having the following solubility profile with the solvent mixture: Let’s say we have to extract different components and all of them are soluble in this mixture. Since carbon dioxide is non-polar and acetic acid is polar, the mixture will be somewhere in the mid-polar region. Here, we have taken a mixture of carbon dioxide and acetic acid. ![]()
