摘　　要：以醋酸甲酯、甲醛为原料合成丙烯酸甲酯为探针反应,利用微反色谱实验装置,经过大量实验筛选出具有催化作用的K+/SiO2型、Li+/SiO2型碱性催化剂,其酯化率效果较好,并对其比表面积(BET)、孔径分布进行了表征和评价。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 hasic catalysts have relatively better esterifying rate effect. Besides, their BET and vulva dimension were characterized and evaluated.
