3. Phase-transfer catalyst
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

4. The reaction of 1-chloro-octane with NaCN in water does not give cyanooctane even
if the reaction mixture is stirred for several days
