Heat capacities of liquid long-chain alkanes

Abstract Liquid heat capacities of n -octadecane, n -nonadecane, n -docosane, n -octacosane, n -triacontane, n -hexatriacontane and n -pentacontane in the temperature range 373–473 K and of squalane and 2, 6, 10, 14-tetramethylpentadecane, in the temperature range 303–403 K have been measured by DSC. Experimental results were used to verify the applicability of the Benson group contribution method to heavy n - and iso -alkanes.
