Phase Equilibria in Sections of the Urea–Ethylene Glycol–Water System at Low Temperatures

Phase equilibria in sections of the urea–ethylene glycol–water system were studied by visual polythermal analysis at temperatures of 0 to –66°C. The urea-to-ethylene glycol ratio in the sections was varied from 3 : 1 to 1 : 3. Mixtures that form low-temperature eutectics were identified and were cha...

Zusammenfassung:Phase equilibria in sections of the urea–ethylene glycol–water system were studied by visual polythermal analysis at temperatures of 0 to –66°C. The urea-to-ethylene glycol ratio in the sections was varied from 3 : 1 to 1 : 3. Mixtures that form low-temperature eutectics were identified and were characterized as promising as new anti-icing agents with good ice-melting capacity.
