Thermodynamics of some nucleic acid bases and nucleosides in water, and their transfer to aqueous glucose and sucrose solutions at 298.15 K

Aqueous solutions of pyrimidine nucleic acid bases. Solute-solvent interactions

“…The experimental enthalpies of solution ⌬ sol H m , enthalpies of sublimation ⌬ sub H m , partial molar volumes V 2 Њ and partial molar heat capacities CЊ p,2 reported earlier [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] [7], VЊ 2 [6], ⌬HЊ sol [9]); 20. 1,3-dimethyl-5-butyl (CЊ p,2 [7]), VЊ 2 [6], ⌬HЊ sol [9] [7], VЊ 2 [7], ⌬HЊ sol [8]); 25.…”

Saturation molalities and standard molar enthalpies of solution of cytidine(cr), hypoxanthine(cr), thymidine(cr), thymine(cr), uridine(cr), and xanthine(cr) in H2O(l)

“…For uridine(cr), Stern and Swanson [22] give D sol C p;m ¼ ð146 AE 33Þ J AE K À1 AE mol À1 . Also, Kishore et al [46] report values of the standard partial molar heat capacity C p;2;m for aqueous solutions of thymidine, thymine, and uridine. Their [46] value for C p;2;m for thymine(aq), together with the value [41] of the standard molar heat capacity C p;m ¼ 151:4 J AE K À1 AE mol À1 for thymine(cr), gives D sol C p;m ¼ 90 J AE K À1 AE mol À1 .…”

Vapour pressures, molar enthalpies of sublimation and molar enthalpies of solution in water of five halogenated derivatives of uracil

“…The calorimeter was formed from a container of total volume 80 cm 3 and normal working volume 65 cm 3 that was fitted with two thermistors each with a nominal resistance of 150 . The calorimeter is submerged in a stirred water thermostat bath whose temperature is controlled to better than 1 mK.…”
