【Abstract】 The reaction for synthesis of 2-ethyl-2-phenyl-3-bromo-3-butenal from 1-phenyl-2-ethyl-2,3-butadienol and Br2 was carried out in glass microchannel reactor.The effect of flow rate and reaction time on yield carried in microfluidic chip was determined.The reaction was found to be more efficient than that in a round-bottomed flask with vigorous sterring.The demonstrated advantages of organic synthesis in microfluidic chip include faster reaction rate,less consumption of reactants and labor,and less contamination to environment,which proves microfluidic chip to be a powerful tool for synthetic application.更多还原
