Vapor-Pressures and Molar Enthalpies of Sublimation for 5-Alkyl Derivatives of 1,3-Dimethyluracil
The results of vapour-pressure measurements for several 5-alkyl derivatives of 1,3-dimethyluracil are presented along with calculated molar enthalpies of sublimation Delta(s)(8)H(m). The results show a nonlinear erratic dependence of Delta(s)(8)H(m) on the number of carbon atoms in the alkyl substituent in position 5 of 1,3-dimethyluracil.
