填料精馏柱实验装置的改造与创新

INPROVEMENT OF SET UP OF LABORATORIAL PACKED FRACTIONATING COLUMNS

改造与创新了一套在常压下进行教学及科研实验的填料精馏柱性能测定小型装置，它具有测定时对系统的干扰小、平行测量数据的重复性好、数据准确、可靠，以及操作方便，消耗试剂少等优点，值得推广应用。

A novel set up of packed fractionating column has been worked out and its efficiency in teaching and scientific research is assessed at normal pressure.The results indicate that the new set-up partakes some advantages,such as no interference to the balance of original system,well duplication of data accurate and reliable,easy operation and less expense of chemicals.Thus it is worthy of expansive applicability.
