Step 2: Phenol and Aniline Reaction

In a round-bottom flask, mix phenol and aniline in the presence of sodium hydroxide. This reaction will form a sodium salt.

Step 3: Chlorination

Add sodium hypochlorite (NaOCl) to the reaction mixture. This will introduce chlorine atoms to the compound.

Step 4: Hydrolysis

Hydrolyze the chlorinated compound by adding hydrochloric acid (HCl). This will replace the chlorine atoms with hydroxyl groups, resulting in hydroxyquinoline.

Step 5: Reflux

Set up a reflux condenser and heat the mixture to reflux. This ensures the reaction proceeds efficiently.

Step 6: Neutralization

After refluxing, carefully neutralize the mixture using sodium hydroxide (NaOH). Ensure that the pH is adjusted to a specific range for optimal results.

Step 7: Isolation

Extract the hydroxyquinoline compound using an organic solvent like ethanol. Filter the solution to obtain the solid hydroxyquinoline product.

Step 8: Drying

Dry the obtained hydroxyquinoline product thoroughly to remove any residual solvent.

Conclusion

Making hydroxyquinoline at home is an exciting venture for chemistry enthusiasts. This compound’s diverse applications and unique properties make it a valuable addition to your chemical repertoire. However, remember to exercise caution and adhere to safety guidelines when working with chemicals.

Now that you know how to make hydroxyquinoline at home, you can embark on your chemical journey and explore the possibilities this compound offers.
