Abstract

"USO DE SAIS DE AMÈNIO DE MONOAMIDAS DE áCIDO FTáLICO, AGENTE DE ARREFECIMENTO AQUOSO, E, CONCENTRADO DE PROTEçãO DO RADIADOR". A invenção refere-se aos agentes de arrefecimento aquosos possuindo propriedades de inibição de corrosão de espaço de vapor, em particular para a fase de entrada de motores de combustão, após a qual o agente de arrefecimento é drenado (fluídos estreantes de motor), contendo pelo menos um sal de amónio de monoamidas de ácido ftálico de fórmula (I), na qual R¬ 1¬ e R¬ 2¬ podem ser iguais ou diferentes e são hidrogênio ou um radical C~ 1-~C~ 20-~alquila linear ou ramificado, cíclico ou acíclico e A¬ +¬ é um cátion de amónio.
