Extraction

The process of extracting a compound from a mix of compounds by exploiting the compound’s greater solubility in one liquid as opposed to another one

Topics

• Partition Coefficient

$W_{1(n)}=W_i{\left(\frac{V_1}{K{V}_2+V_1}\right)}^n$

• $W_{1(n)}$ is the amount of compound in solvent 1 after $n$ extractions
• $n$ is the number of extractions
• $W_i$ is the initial amount of substance in the entire solution
• $V_1$ is the volume of solvent 1
• $V_2$ is the volume of solvent 2
• $K$ is the partition coefficient of the compound of interest for $\frac{\text{solvent 2}}{\text{solvent 1}}$
