Phase transfer catalyst is a catalyst that enables the migration of a reactant from one phase into another. Phase-transfer catalysis is a special form of heterogeneous catalysis. Ionic reactants are frequently soluble in an aqueous phase, but insoluble in organic phase in the absence of the Phase Transfer Catalyst. The catalyst acts as a detergent for solubilizing salts into the organic phase. The catalyst is sometimes employed in liquid/solid and liquid/gas reactions. As evident in the name ... Read more
