What is Vapour Pressures, Molar Enthalpies of Sublimation and Molar Enthalpies of Solution in Water of Five Halogenated Derivatives of Uracil about?

Uracil, 5-fluorouracil, 5-chlorouracil, 5-bromouracil and 6-chlorouracil (6-chloro-2,6-dihydroxypyrimidine) , 5-iodouracil, with molar masses of 0.1121 kg • mol -1 , 0.1301 kg • mol -1 , 0.1465 kg • mol -1 , 0.1910 kg • mol -1 , 0.1465 kg • mol -1 , 0.2380 kg • mol -1 respectively, were purified by repeated crystallization. The mass fraction purity of each substance was greater than 0.99, as determined by a Du Pont 910 differential scanning calorimeter with a 1090 thermal analyzer.
