![]() Phase transfer catalysts are especially useful in green chemistry - by allowing the use of water, the need for organic solvents is reduced. Phase transfer catalysis refers to the acceleration of the reaction upon the addition of the phase transfer catalyst.īy using a PTC process, one can achieve faster reactions, obtain higher conversions or yields, make fewer byproducts, eliminate the need for expensive or dangerous solvents that will dissolve all the reactants in one phase, eliminate the need for expensive raw materials and/or minimize waste problems. The catalyst functions like a detergent for solubilizing the salts into the organic phase. Ionic reactants are often soluble in an aqueous phase but insoluble in an organic phase in the absence of the phase transfer catalyst. Phase transfer catalysis is a special form of heterogeneous catalysis. In chemistry, a phase transfer catalyst or PTC is a catalyst that facilitates the migration of a reactant from one phase into another phase where reaction occurs.
