Research on High-Purity Acetic Acid Purification Technology and Its Industrial Application

摘要

高纯度醋酸作为重要的基础有机化工原料，在电子化学品、医药中间体及高端材料等领域具有广泛应用。随着精细化工产业的发展，对醋酸纯度与杂质控制提出了更高要求。传统生产工艺在脱水、去杂及稳定控制方面存在一定局限，难以满足高端应用场景的质量标准。围绕醋酸精制过程中的关键问题，对精馏分离、吸附净化、膜分离及复合工艺等技术路径展开系统分析，结合工业实践探讨其工艺优化与集成应用模式。通过对影响纯度提升的关键因素进行深入研究，提出具有工程可行性的技术方案，为高纯度醋酸的规模化生产与质量稳定提供理论依据与实践参考。

Abstract

High-purity acetic acid, as an important basic organic chemical raw material, is widely used in electronic chemicals, pharmaceutical intermediates, and high-end materials. With the development of the fine chemical industry, higher requirements have been put forward for the purity and impurity control of acetic acid. The traditional production process has certain limitations in dehydration, impurity removal, and stability control, making it difficult to meet the quality standards of high-end applications. Focusing on the key issues in the acetic acid purification process, a systematic analysis of distillation separation, adsorption purification, membrane separation, and composite processes was conducted. Combined with industrial practice, the process optimization and integration application mode were discussed. Through in-depth research on the key factors affecting purity improvement, a technically feasible solution was proposed, providing theoretical basis and practical reference for the large-scale production and quality stability of high-purity acetic acid.
