| Abstract: | In this paper,probe reaction was based on the synthesis of methyl acrylate with methyl acetate and formaldehyde as raw materials,microreaction-spectrum fixed bed reaction device was used in the experiment,K /SiO2 and Li /SiO2 type basic catalysts ere screening through many experiments.The basic catalysts have relatively better esterifying rate effect.Besides,their BET and vulva dimension were characterized and evaluated. |
