新型泵式沸点仪

The New Motive Cottrell Pump Ebulliometer

探讨了热式沸点仪的不足，提出了新型的泵式沸点仪，建立了一套泵式沸点仪测常压或负压下汽液平衡数据的装置，该装置适用面广，可用于具有缔合反应及汽相易凝固这样复杂系统的汽液平衡数据测定，能满足含甲醛多活性溶剂等复杂系统的测试要求。

The disadvantage of the cottrell pump ebulliometer hasbeen researched and thenew motive cottrell pump ebulliometer is designed.Setting up a set of motive cottrell pump ebul-liometer,which is able to measure isobar vapor liquid equillibria(VLE)data on the atmosphere orthe vacuum for various mixtures.It is possible there are chemical reactions in the mixture liquid,there is solidification in the mixture vaper,too。
