Simultaneous correlation of the excess enthalpy and W-shaped excess heat capacity of 1, 4-dioxane- n-alkane systems by PRSV-HVOS CEOS / Simultano korelisanje dopunske entalpije i dopunskog toplotnog kapaciteta sa w-oblikom eksperimentalnih tačaka kod sistema 1,4-dioksan+n-alkani pomoću prsv-hvos ceos
(Serbian Chemical Society, Belgrade, 2003)
In this work the Peng-Robinson-Stryjek-Vera (PRSV) equation of state coupled with the Huron-Vidal-Orbey-Sandler (HVOS) rule was tested for the correlation of the excess enthalpy (HE) and the excess heat capacity (cp E) ...
Temperature dependence of the Kovats retention indices for alkyl 1, 3-diketones on a DB-5 capillary column / Temperaturna zavisnost kovačevih retencionih indeksa 1,3-diketonan a DB-5 kapilarnoj koloni
(Serbian Chemical Society, Belgrade, 2004)
A series of alkyl 1,3-diketones were used to study the temperature dependence of the Kovats retention indices in the temperature range 130–190 ºC (403–463 K). The temperature dependence is described by the empirical equation ...
