Exploring the Use of Polyols, Corn, and Beet Juice for Decreasing the Freezing Point of Brine Solution for Deicing of Pavements

Deicing of pavements is essential to ensure safe and timely movement traffic in geographical locations where snow ice events are anticipated. State local municipalities employ brine solution with 23.3 wt% sodium chloride (NaCl) available the form rock salt deice pavements. Unlike water, does not freeze until temperature falls below ?21.0 °C, i.e., freezing point water depressed by °C addition NaCl. The plays a key role deicing Unfortunately, further increase content lower solution. In this study, different combinations agricultural products such as polyols including sorbitol, maltitol, mannitol (23.3 NaCl water), NaCl-juice (corn beet juice) were investigated achieve depressions for potential applications extremely cold areas. Different weight fractions polyols-brine solutions ranging from 7.14% 27.77% considered, corresponding points determined. While sorbitol-brine exhibited lowest ?38.1 at higher concentration, maltitol-brine ?35.6 same concentration. Based on °Brix value, juice had almost three times more soluble solids compared corn juice. Adding 70% lowered up ?23.5 °C.
