丁二酸结晶动力学研究
Study on the crystallization kinetics of succinic acid
丁二酸作为碳四中间体化学品,在合成批量工业品和消费品的过程中至关重要。对丁二酸晶体的成核过程与取向生长方式进行系统探究,多维度物相结构表征结果表明:在X射线衍射谱图中,丁二酸在结晶过程中形成了良好的结晶相;在光学显微镜谱图中,丁二酸在成核过程中形成了粒径饱满的菱型晶体。同时,测定了丁二酸溶液结晶诱导期、二次成核速率、生长速率等一系列动力学数据,结果表明:晶体的成核速率和生长速率都与过饱和度有关,低过饱和度更有利于晶体生长,降低结晶冷却速率有利于生产粒径较大的晶体。
As a C4 intermediate chemical,succinic acid plays a crucial role in the synthesis of bulk industrial and consumer products.In this research,we conducted a systematic exploration of the nucleation process and oriented growth mechanism of succinic acid crystals,with multi-dimensional structural characterization results indicating that:The XRD spectra show that succinic acid forms a well-defined crystalline phase during crystallization;The optical microscopy images reveal that succinic acid crystallizes into rhombic crystals with substantial particle sizes.At the same time,a set of kinetic data such as crystallization induction period,secondary nucleation rate,and growth rate of succinic acid solution were determined,which indicates that:the rates of crystal nucleation and growth are both associated with the supersaturation ratio,where a lower supersaturation ratio is more conducive to crystal growth,suggesting that decreasing the cooling rate during crystallization aids in obtaining larger crystals.
