“…The boiling point of methanol is low (∼337.15 K). In addition, cytosine forms a monohydrate compound in pure water, which decomposes and transforms into an anhydrous compound at temperatures above 333.15 K. Therefore, the main work of this paper is to determine the solubility data of cytosine in fourteen pure solvents (water, methanol, ethanol, n -propanol, isopropanol, n -butanol, iso-butanol, 2-butanol, tert -butanol, 1-pentanol, isoamyl alcohol, hexanol, 1-octanol, and DMSO) from 288.15 to 328.15 K by the gravimetric method − and correlate the solubility data using the modified Apelblat equation, , the λ h model, − and the van′t Hoff equation. − …”

The solubility of cytosine in fourteen pure solvents at 288.15–328.15 K was determined by the gravimetric method, and the solubility data were correlated using the modified Apelblat equation, the λh model, and the van′t Hoff equation. The relative deviation (RD), average relative deviation (ARD), and root-mean-square deviation (RMSD) values of the above models were calculated. The results showed that the three models have a good correlation with experimental data. Especially, the modified Apelblat equation had the best correlation effect on solubility. Theoretical knowledge of solubility is essential for the crystallization of cytosine.
