This paper presents two types of ehulliometer: CP--Ⅰ and CP-Ⅱ, shows in detail the ideas and principles of each unit of the ebulliometers.The new ebulliometers, which are the multipurpose instruments designed for mceting the more needs of measuring vapour-liquid equilibrium data, have the characteristics of both the ebulliometer and the still. As stills, they can be used to measure vapour-liquid equilibrium data of the miscible system and the partially miscible one; and as ebulliometers, to meet the pseudo-static, the exchanging, and the boiling point analysis methods for measuring vapour-liquid equilibrium data. In particular, type CP-II, which has the functions of determining factor of the holdup and the reflux ratio, is used to measure the terminal values (K~∞, r~∞). The functions of each unit and the characteristics of the instruments are tested and the expected results are obtained.
