【Abstract】 Hydrogenation is an important reaction in organic synthesis and has been widely used.At present, most hydrogenation reactions are carried out intermittently in high-pressure reactors, which has such disadvantages as explosion risk, low conversion rate and low selectivity.Therefore, it is necessary to develop a new, safe and efficient hydrogenation process.Microchannel reactor can accurately control the temperature and reaction time, and it features uniform mixing, high mass transfer performance, greatly improved reaction selectivity and production yield, as well as notably reduced catalyst loss.The hydrogenation reactions of alkenes, alkynes, aldehydes, ketones and nitro groups in microchannel reactors are summarized.As a technology attracting widespread attention, continuous flow micro-reaction hydrogenation enjoys high development prospects, and is one of the research directions of chemical synthesis in the future.更多还原
