| Abstract: | The method of outside cooling and then generating partial condensation to offer reflow was used to realize azeotropic rectification that is effective in water separation and easy in control of reflow. By the application of esterification for n-butyl lactate, n-butyl acetate and iso-amyl acetate, it showed that this method improved the conversion of the acid by 2%~3% and reduced the loss of organic in waste water by 9%~12% compared with that of common water separator by rectification. |
