Propylene glycol - Wikipedia

WebbGlycols and other deicing chemicals are efficient freezing-point depressants--that is, they act as a solute to lower the freezing point of the solvent, in this case water. Propylene glycol (CH 3 CHOHCH 2 OH) or ethylene glycol (HOCH 2 CH 2 OH) generally is the major component of aircraft deicers, making up 30 to 70% of the solution. WebbFreeze Protection – The lowest possible operating temperature for a solution of glycol and water (i.e. at no point will ice crystals form at temperatures above the freezing point). When designing a system, select a glycol concentration that provides freeze protection at least 3°C (5°F) lower than the lowest anticipated temperature. covid vaccine clinics missoula mt
