Phase transfer catalyst is used when oxidizing methoxybenzyl alcohol because it is able to dissolve in both the ethyl acetate and the aqueous layers.
What is phase transfer catalyst?
A phase-transfer catalyst, often known as a PTC, is a catalyst that helps a reactant move from one phase into another where a reaction takes place. Heterogeneous catalysis features a unique subset known as phase-transfer catalysis.
In the absence of a phase-transfer catalyst, ionic reactants are frequently soluble in an aqueous phase but insoluble in an organic phase. When introducing salts into the organic phase, the catalyst acts as a detergent. When a phase-transfer catalyst is added, the reaction is said to be catalyzed, which means it is accelerated.
