Sažetak

U ovom radu razmotrene su mogućnosti predskazivanja vrednosti toplote isparavanja na bazi principa korespondentnih stanja. Prikazane su predložene funkcije ΔS(0) i ΔS(1), kako u diskretnoj, tako i u analitičkoj formi. Diskretne vrednosti su korelisanjem prevedene u analitičke izraze. Predskazivanje vrednosti toplote isparavanja testirano je na podacima za 80 nepolarnih supstanci sa ukupno 397 eksperimentalnih vrednosti. Najbolje prediktivne osobine pokazao je model, koji su predložili Sivaraman, Magee i Kobayashi.

Ključne reči

toplota isparavanja; faktor acentričnosti; princip korespondentnih stanja; nepolarne supstance
