生物基丁二酸结晶过程研究
Research on the Crystallization Process of Biobased Succinic Acid
丁二酸是一种重要的C4平台化合物,广泛应用于食品添加、医药、精细化工及降解聚酯合成等行业。生物基丁二酸因其原料来源丰富、碳排放低和发展可持续等特点,发展迅猛,已逐步取代石油基丁二酸成为市场的主流产品。生物基丁二酸的制造包括发酵、分离、提纯等多个过程,其中结晶是生物基丁二酸生产的重要工序之一,对产品纯度和晶体粒度有显著影响,决定了产品质量。本文从结晶机理切入,详细阐述了生物基丁二酸结晶的影响因素,旨在为该技术的工业化应用提供参考。
Succinic acid is an important C4 platform compound widely used in industries such as food additives, pharmaceuticals, fine chemicals, and degradable polyester synthesis. Biobased succinic acid has developed rapidly due to its abundant raw material sources, low carbon emissions, and sustainable development. It has gradually replaced petroleum based succinic acid as the mainstream product in the market. The production of bio based succinic acid includes multiple processes such as fermentation, separation, and purification. Among them, crystallization is one of the important processes in the production of bio based succinic acid, which has a significant impact on product purity and crystal size, and determines product quality. This article starts from the crystallization mechanism and elaborates on the influencing factors of biobased succinic acid crystallization, aiming to provide reference for the industrial application of this technology.
