✦ Synopsis
The results of vapour-pressure measurements for several 5-alkyl derivatives of 1,3-dimethyluracil are presented along with calculated molar enthalpies of sublimation D g s Hm. The results show a nonlinear erratic dependence of D g s Hm on the number of carbon atoms in the alkyl substituent in position 5 of 1,3-dimethyluracil.
