以ZSM-5为原料,采用浸渍法将其交换成HZSM-5,以HZSM-5为催化剂,对以冰乙酸和正戊醇为原料合成乙酸戊酯的反应条件进行了研究。研究表明,以1.0m ol/L硫酸浸渍后的ZSM-5催化活性最高,当醇酸摩尔比为1.1∶1,催化剂用量为0.4g,反应时间为90m in,反应温度为125—135℃,酯化率可达82.5%。 ZSM-5 was used as raw material, and HZSM-5 was exchanged by impregnation method. The reaction conditions of synthesizing amyl acetate from glacial acetic acid and n-amyl alcohol were studied by using HZSM-5 as catalyst. The results showed that ZSM-5 had the highest catalytic activity after impregnated with 1.0 mol / L sulfuric acid. When the molar ratio of alkyd was 1.1: 1, the amount of catalyst was 0.4 g, the reaction time was 90 min, the reaction temperature was 125-135 ℃, Esterification rate up to 82.5%.
