| titleOfInvention |
Synergistic combinations of carboxylates for use as freezing point depressants and corrosion inhibitors in heat transfer fluids |
| abstract |
An aqueous fluid composition having a C1-C2 carboxylic acid salt and a C3-C5 carboxylic acid salt is used as a heat transfer fluid that provides improved heat transfer properties and improved corrosion protection. Such properties are desired for fluids used as an antifreeze coolant in automotive engines. The addition of a C6-C2 carboxylic acid further improves corrosion protection. The addition of hydrocarbyl triazoles or thiazoles also further improves corrosion protection. One specific embodiment of the present invention includes a solution of potassium formate, sodium propanoate, and sodium heptanoate in a weight ratio of 20:20:5, respectively, where the pH of the solution is between 8 and 9.5. |
