Enthalpies of solution in water, vapor pressures, and enthalpies of sublimation were determined for cytosine and a number of crystalline derivatives of cytosine: 1-methylcytosine, 1-methyl-N
4-hydroxycytosine, 1,5-methyl-N
4-methoxycytosine, 1,N
4,N
4-trimethylcytosine, 1,5,N
4-trimethylcytosine, 1,5-dimethyl-N
4-methoxycytosine, and l,N
4-dimethyl-5-ethylcytosine. Enthalpies of hydration were calculated. The latter were analyzed on the basis of the group additivity method. The relation between enthalpy of hydration and polarity of compounds is discussed. 相似文献
