用分子筛作催化剂,在釜式反应器内对丁醇和乙酸的液相酯化反应进行了研究。考察了分子筛硅铝比、催化剂用量、反应物摩尔比和反应温度对酯化反应的影响。当醇酸摩尔比为1.1、HZSM-5(50)用量为3%、反应温度为130℃时,5小时酯化转化率大于93%。本文还提出了在无催化剂时和以 HZSM-5(50)为催化剂时的酯化反应动力学模型。 Using molecular sieve as catalyst, liquid-phase esterification of butanol and acetic acid was studied in a pot reactor. The effect of the molar ratio of silica to alumina, the amount of catalyst, the molar ratio of reactants and the reaction temperature on the esterification was investigated. When the molar ratio of alkyd is 1.1, the amount of HZSM-5 (50) is 3% and the reaction temperature is 130 ℃, the conversion of esterification is more than 93% in 5 hours. In this paper, the kinetic model of esterification in the absence of catalyst and HZSM-5 (50) as catalyst was also proposed.
