Abstract

"USO DE UM áCIDO CARBOXìLICO OU DE UMA MISTURA DE áCIDOS CARBOXìLICOS OU DE SEUS SAIS". ácidos carboxílicos ou os seus sais são adequados para uso em sistemas de resfriamento onde é exigida baixa condutividade elétrica. As composições são de uso particular em pilhas de célula de combustível. Os sais preferidos são os de aminas. Os sais podem ser usados com um diminuidor do ponto de congelamento do álcool líquido, tal como monoetileno glicol. Tiazóis e/ou triazóis podem ser incluídos, bem como outros inibidores de corrosão conhecidos na tecnologia.
