Abstract
A heat transfer fluid containing a glycol component and a second component selected from the group consisting of 1,3-dioxolane, 2,2-dimethyl-1,3-dioxolane, glycerol formal, solketal, and 1,3-dioxanes is disclosed. The heat transfer fluid can also optionally contain corrosion inhibitors, C.sub.1-3 alcohols, urea, imidazole or alkali metal salts. These fluids are useful as low temperature heat transfer fluids, are stable to aqueous buffers and may be used neat or as aqueous solutions over a wide range of concentrations.
