| 摘 要： | 在前期液-液相平衡研究的基础上,得出正丁醇、乙酸乙酯及乙酸丁酯在萃取2,3-丁二醇时的不同特点.并根据其特点,分别设计了2条创新的间歇-循环的萃取-精馏耦合工艺.根据乙酸乙酯、乙酸丁酯分配系数小、相比(质量比)要求较大的特点,设计萃取-精馏耦合工艺一(即溶剂循环、料液间歇进料),该工艺具有相比逐渐增大、溶剂循环萃取的特...

| Abstract: | The characteristics of three solvents including n-butanol,ethyl acetate and butyl acetate were confirmed on the basis of the liquid-liquid equilibrium data of prior-phase lab experimental study. According to the characteristics,two innovative batch-continuous extraction technological routines were designed and studied, respectively. When ethyl acetate or butyl acetate is taken as extraction solvent,the distribution coefficients are small and big phase ratio(mass ratio) is necessary to satisfy 2,3-butanediol... |
