Abstract

In this work, production of ethyl acetate (EtAc) using Fischer esterification between acetic acid (AcOH) and ethyl alcohol (EtOH) is presented. Batch kinetics was developed with EtOH as the limiting reactant to avoid the problems associated with unreacted ethanol in the final product. Regression was performed to estimate the parameters of the Langmuir Hinshelwood type kinetic equation. Reaction mass obtained during kinetics was subjected to separation and purification. Molecular sieves (MS) were used to remove water. Distillation (simple and extractive distillation – with entrainer, dimethyl sulfoxide, DMSO) was used to obtain almost pure AcOH, EtOH, EtAc and DMSO. Future work in reactive separation environment is indicated. Use of EtOH as the limiting reactant, use of MS for water removal and complete separation sequence are important features of this work.
通过费歇尔酯化法生产乙酸乙酯:使用过量乙酸和完整的分离程序
本研究介绍了利用乙酸(AcOH)和乙醇(EtOH)之间的费歇尔酯化反应生产乙酸乙酯(EtAc)的过程。为了避免最终产品中未反应乙醇带来的问题,我们开发了以 EtOH 为限制反应物的批次动力学。通过回归估算了 Langmuir Hinshelwood 型动力学方程的参数。对动力学过程中获得的反应质量进行了分离和纯化。使用分子筛(MS)去除水分。通过蒸馏(简单蒸馏和萃取蒸馏--使用夹带剂二甲基亚砜 DMSO),获得了几乎纯净的 AcOH、EtOH、EtAc 和 DMSO。为今后在反应分离环境方面的工作指明了方向。使用 EtOH 作为限制反应物、使用 MS 去除水分和完整的分离顺序是这项工作的重要特点。
