I reacted 2,4 - dinitrophenyl hydrazine with salicylaldehyde to form a hydrazone using ethanol as solvent. Which solvent will be suitable for the recrystallization of the hydrazone since its no longer soluble in ethanol?
To recrystallize the hydrazone from 2,4-dinitrophenyl hydrazine and salicylaldehyde, consider these solvents since ethanol is ineffective:
Please note that choose the solvent based on solubility tests for effective recrystallization
1. Water
2. Dilute Acetic Acid
3. Methanol
4. Acetonitrile
5. Dichloromethane/Hexane mix
Steps:
1. Test Solubility: Select a solvent that dissolves the hydrazone when hot but allows crystallization when cooled.
2. Dissolve and Cool: Heat to dissolve, then cool to precipitate.
3. Filter and Dry: Collect and dry the crystals.
