摘要：

For the extension of the UNIVAP group contribution method (UNIversal heats of VAPorization) it was necessary to measure heats of vaporization of substances containing some special functional groups. Measurements were performed with a quasi-isothermal microcalorimeter in order to obtain enthalpies of vaporization of pure substances with the accuracy needed. Experiments were made in a temperature range from 313 to 358 K for 3-buten-1-ol, 1-penten-3-ol, 5-hexen-1-ol, 3,3-dimethyl-1-butanol, 2,4,4-trimethyl-1-pentanol and 2,2-dimethyl-3-pentanol. The UNIVAP parameters were fitted and using some literature data for amines and aromatic hydrocarbons, the parameter-matrix was extended.
