摘要
选型并采用一种往复振动筛板塔对2,2–二硝基丙醇（DNPOH）的反应液进行萃取,确定了较佳的萃取条件：萃取温度为35℃,振动频率17.5 Hz,振幅15 mm,溶剂比R=0.5,界面位置控制在视镜中部。较佳萃取条件下,萃取率达到99.5%~100%。
A continuous reciprocating plate extraction column was selected and designed to extract 2,2-dinitropro-panol（DNPOH） reaction solution,and better extraction conditions were determined： the extraction temperature is 35℃,the vibration frequency is 17.5 Hz,the vibration amplitude is 15 mm,the solvent ratio R＇is 0.5,the interface position is controlled in the middle of mirror.The extraction yield reaches 99.5%~100% under such conditions.
