【摘要】 提供了一种从烟叶浸膏中提取精品茄尼醇的分离集成技术,设计了一系列该分离技术中所需的实验设备,包括球形夹套式皂化萃取装置、超低温离心结晶装置及连续中压柱层析分离装置。采用分离集成技术及设备,成功将质量分数为20%左右的烟叶浸膏经过皂化萃取,得到质量分数为59%左右的半成品茄尼醇,再通过结晶得到质量分数为80%左右的高纯度茄尼醇,最终通过柱层析和重结晶得到质量分数为95.5%的精品茄尼醇,整个实验过程的得率为70%。克服了现有技术中能耗大、溶剂污染严重等缺点。更多还原

【Abstract】 A separation integrated technology for isolating refined solanesol from tobacco extracts was provided.Some experimental installations applied in the separation integrated technology were designed,including saponification and extraction installation,cryogenic centrifugation crystallization installation and continuous medium pressure chromatography separation installation.With the separation integrated technology and installations,semi-finished products solanesol(mass fraction 59%) was successfully got from tobacco extracts(mass fraction 20%) by saponification and extraction,again,high purity solanesol(mass fraction 80%) by crystallization,finally,competitive products solanesol(mass fraction 95.5%) by chromatography and recrystallization.The yield of the whole experiment is 70%,overcoming disadvantages in the existing technology such as huge consumption of energy,heavy pollution of solvents.更多还原
