Synergistic combinations of carboxylates for reducing temperature of congelation and retardation of corrosion in heat-transferring liquids

摘要

The use of a composition comprising a mixture of a C 1 - C 2 carboxylic acid salt and a C 3 - C 5 carboxylic acid salt as a coolant composition in automotive engines is described. The aqueous compositions may further comprise a hydrocarbyl triazole or a hydrocarbyl thiazole
