In this paper,the continuous flow process of glyoxylic acid synthesis by oxidation of glyoxal with hydrogen peroxide was studied.Using hydrogen peroxide and glyoxal as raw materials,the continuous flow process of synthesizing glyoxylic acid by liquid phase oxidation was clarified by observation,and on this basis,the best process conditions were worked out.The experimental results show that this process can give full play to the excellent mass and heat transfer characteristics of microchannel reactor,which is helpful to shorten the reaction time and increase the reaction rate.It is an effective process.
