摘要
1 INTRODUCTIONVapor-liquid equilibrium(VLE)data are useful for the study of solution properties ofnon-ideal mixtures as well as for the design of the separation equipment.Then-methylpyrrolidone(NMP)is a new-type and excellent solvent which can be used in somechemical engineering separation processes.The NMP sucks up moisture so easily that it isnecessary to study the VLE relations of the NMP-HO binary system,
