High-pressure reactions A more esoteric technique is to carry out the reaction at very high pressures ( 10kbar), thus shifting the equilibrium to the side of the components which have the smaller volume. Some transformation of the products must be carried out as soon as they are removed from the reactor, in order to prevent re-equilibration. A recent review gives an …
