ABSTRACT
In addition to the previously reported data on the molar enthalpy and heat capacity of dissolution of 2,6- dimethylglycoluril (being a racemic trans-N-dimethyl-substituted bicyclic bisurea) as well as achiral 2,4- dimethylglycoluril in water, the similar missing results for achiral cis-analogue, 2,8-dimethylglycoluril, have been determined in the temperature range between (278.15 and 313.15) K and at p = 99.6 kPa. The findings were briefly discussed in conjunction with the mentioned data for other N-dimethylglycolurils.
