This is a liquid-phase process, operated in a hydrocarbon solvent at an intermediate pressure, using a heterogeneous oxide catalyst such as chromia on silica/ alumina. (2) A fractional crystallization process used to freeze-concentrate beer and fruit juices. Formerly used in the production of p-xylene. (3) A two-stage process for dehydrogenating butane to butadiene
