Title (EN) SYNERGISTIC COMBINATIONS OF CARBOXYLATES FOR USE AS FREEZING POINT DEPRESSANTS AND CORROSION INHIBITORS IN HEAT TRANSFER FLUIDS
(FR) ASSOCIATIONS SYNERGIQUES DE CARBOXYLATES UTILISES COMME ADDITIFS ANTIGELS ET INHIBITEURS DE CORROSION DANS DES FLUIDES DE TRANSFERT THERMIQUE
Abstract: front page image
(EN)Aqueous coolants and heat transfer fluids are disclosed. The compositions comprise aqueous solutions of a mixture of a C1-C2 carboxylate salt with a C3-C5 carboxylate salt. A C6-C12 acid may also be added to the mixture. The aqueous compositions may further comprise a hydrocarbyl triazole and thiazole. The aqueous compositions have good heat transfer properties, low freezing points and low corrosion properties.
(FR)L'invention concerne des liquides de refroidissement aqueux et des fluides de transfert thermique. Les compositions comportent des solutions aqueuses d'un mélange de sel carboxylate en C1-C2 avec un sel carboxylate en C3-C5. Un acide en C6-C12 peut également être ajouté au mélange. Ces compositions aqueuses peuvent, en outre, comprendre un triazole hydrocarbyle et un thiazole. Elles présentent de bonnes propriétés de transfert thermique, un faible point de congélation et de faibles propriétés corrosives.
