Abstract
The solubility of components in the NaClO3 · 2CO(NH2)2-NH2C2H4OH · CH3COOH-H2O system was studied by the visual polythermal method over wide temperature and concentration ranges. In the phase diagram, crystallization fields were determined for ice, urea, diurea sodium chlorate, acetic acid, monoethanolamine acetate, and the compound CO(NH2)2 · NH2C2H4OH · CH3COOH. The compound was identified by chemical, thermogravimetric, and X-ray powder diffraction analyses.
