<h3>Procedural steps are: - </h3>
  1. On a small scale, the reaction is carried out by combining the alcohol, the haloalkane, and the phase transfer catalyst in a conical vial.
  2. To start the reaction, sodium hydoxide (base) is added.
  3. To prevent solvent evaporation, the reaction flask is covered and stirred during the reaction.
  4. TLC monitors the reaction's progress to ensure that no time is wasted.
  5. To remove any remaining water, the reaction solution is dried over calcium chloride.
  6. Column chromatography is used to purify the product, and evaporation is used to collect it.
<h3>What is Catalysis?</h3>

Catalysis is the process of boosting the pace of a chemical reaction by using a catalyst. Catalysts are not consumed in the reaction and so survive it.

So

expect sublimation

The solid will sublime into a gas.
