Heat Capacities in the Solid and in the Liquid Phase of Isomeric Pentanols

Original language description

Isobaric heat capacities in the liquid and in the solid phases of seven isomeric pentanols were measured by adiabatic calorimetry. Results obtained cover the following temperature ranges: 2-methyl-1-butanol from 85 K to 301 K; 2-methyl-2-butanol from 84K to 301 K; 3-methyl-1-butanol from 79 K to 158 K; 3-methyl-2-butanol from 85 K to 301 K; 2,2-dimethyl-1-propanol from 6 K to 381 K; 2-pentanol from 80 K to 301 K; and 3-pentanol from 5 K to 309 K. The temperature and enthalpy of phase transition were also determined. Solid to solid and solid to liquid phase transitions were detected for 2-methyl-2-butanol and for 2,2-dimethyl-1-propanol, and a solid to liquid phase transition was detected for 3-pentanol. Only a glass to liquid phase transition was detected for all the remaining compounds. The heat capacity data in the liquid phase obtained in this work were merged with available experimental data from the literature and critically assessed, and sets of recommended data were developed b

Tepelné kapacity izomerických pentanolů v tuhé a kapalné fázi

Czech description

Tepelné kapacity sedmi větvených pentanolů byly naměřeny v rozmezí od 5 K do 380 K adiabatickou kalorimetrií. Pro měření tepelných kapacit byly použity tři adiabatické kalorimetry s odhadovanou nejistotou 1 %. Teplotní závislost tepelné kapacity byla stanovena pro všech sedm pentanolů. U některých vzorků byl pozorován přechod solid-solid. Výsledky byly porovnány s publikovanými data a byly stanoveny parametry korelačních rovnic.
