Excess enthalpies have been determined at 298.15 K for the binary syst
ems hexanal + n-nonane, and + (n - 1)-nonene, trans-2-butenal + n-nona
ne, + cyclohexane, + (n - 1)-nonene, + (n - 1)-nonyne, and +1-butanol,
and benzaldehyde + n-decane, + (n - 1)-decene, and + 1-hexanol, using
a Calvet-type differential microcalorimeter. The results are fitted w
ith a Redlich-Kister-type polynomial and the UNIFAC group-contribution
model.
