Answer 2

Dry toluene can be prepared by adding molecular sieves (such as 3Å or 4Å) to remove any water present in the toluene. The molecular sieves should be added to the toluene and left to stir for several hours to achieve dry toluene. Alternatively, toluene can be distilled over a drying agent like calcium hydride or sodium wire to ensure it is completely dry.
