Yes, toluene/water combination would be a good binary solvent system for a mixed recrystallization.
Because toluene is a fairly nonpolar chemical and water is polar, they will not dissolve together, making the combination of toluene and water an excellent binary solvent system.
<h3>What is mixed recrystallization?</h3>
- The substance to be crystallized is first dissolved in the smallest quantity of hot "soluble solvent," and then hot "insoluble solvent" is added dropwise until the solution becomes faintly hazy.
- This is how mixed recrystallization happens.
<h3>What is binary solvent?</h3>
- When synthesizing pharmaceuticals and drug precursors, binary solvent mixtures are employed as carriers in HPLC columns.
- For accurate and effective separation of the necessary pharmaceutical components, it is essential to precisely manage the mixture's composition.
- Water-based solutions of ethanol, sugar, and salt.
