Abstract：Microreactors have been widely applied in many fields such as chemical，pharmaceutical， environmental，materials，metalurgy，energy，and medical diagnosis industries due to these advantages，for example，smallvolume，high heat and masstransfer performances，high security，and good controllability. Therein，the global researchers have always focused on intensification of mass transfer and reaction in the microreactors.The structure of microreactors，the enhancements of ultrasonic field，centrifugal field，magnetic field，light and stir have been systematically reviewed. Then，the reasons of intensification of masstransfer and reaction in the microreactors havebeen in-depth analysis.Finally，thedevelopment trends on intensificationof mass transfer and reaction in the microreactors have been prospected.In order to enhance masstransfer and reaction in the microreactors，the folowing measures may be taken：（1） The formation mechanism of droplets， liquid slugs， liquid flows，bubbles，gas slugs and gas flows，and afecting factors and transformation mechanism offluid flow patern in the microreactors have been in-depth-study.（2）The satisfactory reinforcement effect will achieve by using the coupling measures.For example，integration ofspiral microchannels and ultrasonic field，combination of spiral microchannels and photocatalysis，and integration of gas stir and rotating microchannels.（3）The performance optimization and improvement of microreactors have been realized through numerical simulation， experimental study，and scale-up process.The ultimate aim is the application of microreactors in industrial production.

Key words： microreactors； microchannels； microscale； mass transfer；process intensification
