  This paper describe a highly efficient continuous cyclic reaction of concentrated sulfuric acid and aldimine generated in situ using lemon aldehyde and organic amine.The effects of the micromixer type,reaction temperature,catalyst usage,the flow rate and the residence time are considered.The reaction product is neutralized by sodium hydroxide solution,then acid hydrolysis,separating,vacuum distillation,and the drying process,the light yellow oil product is obtained.The reaction time is short,the reaction temperature is precise and controllable,and the product selectivity and yield is high.
