1,4-丁炔二醇(BYD)净化核心技术综述

Review of Core Technologies for 1,4-Butynediol (BYD) Purification

摘要: 1,4-丁炔二醇的工业纯化正面临多重制约——如何选择合适的工艺路线、如何突破现有瓶颈，仍是业内关注的核心问题。文章以精馏、离子交换、吸附和膜分离四种主流净化方案为研究对象，从作用机制、脱除对象、性能特点、现存难点及工业应用程度角度，比较了各自的特点，并结合典型研究梳理了各项技术当前所处的阶段。在多技术耦合方向上，文章回顾了近年来工艺集成领域的进展，同时对接南京工业大学膜科学技术研究所的前期工作，分析膜分离在这一特定体系中的突破可能。从整体上看，精馏凭借成熟稳定的优势，在现阶段工业生产中仍然占据主导；但四种技术均有各自难以克服的短板，相关工艺优化和新材料开发也在同步向前推进。未来要实现高效、高纯净化，仍需多种技术及其集成方案协同发力，多技术耦合已成为该领域的一个基本走向。

Abstract: The industrial purification of 1,4-butynediol is confronted with multiple constraints—how to select a suitable route and how to break through existing bottlenecks remain central concerns. This work examines four mainstream purification schemes: distillation, ion exchange, adsorption, and membrane separation. A comparison is drawn across their separation mechanisms, target impurities, performance characteristics, persistent limitations, and levels of industrial adoption, with representative studies used to clarify the current development stage of each technology. In the direction of multi-technology coupling, recent advances in process integration are reviewed, and previous findings from the Membrane Science and Technology Research Institute of Nanjing Tech University are incorporated to assess the potential breakthrough of membrane separation in this specific system. Overall, distillation still dominates current industrial practice owing to its maturity and reliability; however, each of the four technologies has its own shortcomings that are difficult to overcome, while process optimization and the development of new materials continue to progress in parallel. To achieve efficient and high-purity purification in the future, collaborative efforts from multiple technologies and their integrated solutions will still be required, and multi-technology coupling has become a fundamental trend in this field.
