摘　　要：传统的酯的合成中,一般是以无机强酸为催化剂,比如硫酸。然而硫酸具有强氧化性,故一般以硫酸为催化剂的酯化反应都会有比较多的副反应,环境污染严重,对反应之后的处理也比较复杂,还会对设备造成一定的损害。用碘为催化剂合成酯,具有反应条件温和、操作简单、高效清洁等优点。实验表明:碘能有高效的催化酯的合成反应,而且合成酯的产率都是随着催化剂用量的增加而升高,且它们的产率都是随着时间的增加而升高,当时间增加到某个时间之后,产率变化不明显。The ester synthesis in traditional method, generally based on inorganic acid catalyst such as sulfuric acid. However, sulfuric acid with strong oxidizing, it is generally sulfuric acid as the catalyst for the esterification reaction will have more side effects, serious environmental pollution response after treatment is more complicated, also cause some damage to the equipment. But Iodine catalyzed synthesis of esters, iodine can effectively catalyze ester synthesis, and has the advantages of mild reaction condition, simple operation, clean and efficient.
