【摘要】：共结晶技术是精细化学品、制药等高附加值行业的前沿研究方向。本文以赤藓糖醇为载体,采用熔融共结晶法制备了赤藓糖醇-三氯蔗糖固态复配产品,应用TG-DSC、XRD和SEM等对其结构与性能进行了表征分析;结果表明:熔融共结晶法制备的赤藓糖醇-三氯蔗糖固态复配产品为共晶体,赤藓糖醇-三氯蔗糖共晶体的DSC热分解吸热峰的峰顶温度为156.2℃,而三氯蔗糖的热分解吸热峰的峰顶温度为134.4℃,说明共结晶过程有效提高了共晶体复配产品中三氯蔗糖的热稳定性,共结晶试验中发现晶种加入量和晶种粒度分布是影响赤藓糖醇-三氯蔗糖共结晶产品粒度分布和堆密度的重要因素;当加入晶种的粒度为120~200目,加入量为10 wt%时,熔融共结晶法制备的赤藓糖醇-三氯蔗糖共晶体产品中30~60目的晶体占总质量的91.8%,堆密度可达0.82 g/cm~3。
[Abstract]:Eutectic technology is the leading research direction of high value-added industries, such as fine chemicals and pharmaceuticals. In this paper, a solid mixture of erythritol and trichlorosucrose was prepared by melt eutectic method with erythritol as the carrier. The structure and properties were characterized by TG-DSC-XRD and SEM. The results showed that the solid mixture of erythritol and sucralose was eutectic. The peak temperature of the endothermic peak of DSC and sucrose trichlorohydrin is 156.2 鈩，
