EXTENSION OF THE UNIVAP GROUP-CONTRIBUTION METHOD - ENTHALPIES OF VAPORIZATION OF SPECIAL ALCOHOLS IN THE TEMPERATURE-RANGE FROM 313 TO 358K

For the extension of the UNIVAP group contribution method (UNIversal h eats of VAPorization) it was necessary to measure heats of vaporizatio n of substances containing some special functional groups. Measurement s 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-butano l, 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 a romatic hydrocarbons, the parameter-matrix was extended.
