A method of catalytic reaction uses a micro-reactor (1) with a metal
catalyst (5) or a metal complex catalyst (5) as a solid phase supported
on the inner wall (4c) of a channel (4), a solution (7) dissolving a
reactant as a liquid phase and hydrogen (9) as a gas phase are flown
through the channel (4) in pipe flow state, and the reaction of the
solution (7) and the gas (9) accelerated by the metal catalyst (5) or the
metal complex catalyst (5) is conducted by three phase catalytic reaction
of solid-liquid-gas phases. The metal catalyst (5) or the metal complex
catalyst (5) is incorporated in a polymer, and hydrogenation reaction by
three phase catalytic reductive reaction of a substance to be reduced can
be conducted in short time at good yield. For hydrogenation reaction of
unsaturated organics, the rate of reaction and yield are high when
palladium catalyst is used, and carbonylation reaction can be conducted
if carbon monoxide is used instead of hydrogen.
