【摘要】 测定醋酸叔丁酯-醋酸的汽液平衡数据,用最小方差法关联拟合;采用共沸蒸馏法从醋酸叔丁酯和醋酸混合溶液中提取醋酸叔丁酯,研究共沸蒸馏过程中,温度及回流比对分离效果的影响;由甲醇-水标准体系确定共沸蒸馏塔的等板高度、塔高及塔板效率;研究结果为进一步放大实验提供依据。更多还原

【Abstract】 The separation of tert-Butyl acetate-acetic acid was studied in this work.The influence of different temperature and reflux ra- tio on the separation of tert-Butyl acetate-acetic was studied.And the purity of TBAC reached more than 95%.The VLE data was measured and correlated by The Least Variance Priority Method(LVM).Height equivalent to a theoretical plate(HETP)was evalua- ted by methanol-water.The number of theory plates and the plate efficiency of tert-Butyl acetate-acetic acid were determined.The work provided an effective basis for the further purification research of TBAC.更多还原
