Abstract
"INIBIDOR DE CORROSãO". Verificou-se que a mistura de inibidor de corrosão de pelo menos uma base de inibidor de corrosão (que pode ser um produto de reação Mannich), um solvente selecionado a partir do grupo que consiste em ácidos de C, e seus derivados de ésteres e sais, e opcionalmente um agente tensoativo, é eficaz como um inibidor de corrosão para metais em meios ácidos, especialmente fluidos que contêm ácidos halogênios. O inibidor de corrosão apresentou melhor desempenho em relação a composições inibidoras de corrosão similares ou idênticas onde um álcool tal como metanol é usado como solvente. Possibilidades adequadas não-limitativas para o solvente incluem ácido fórmico, sais de formatos, metil formato, etil formato, benzil formato, sais de formatos de aminas, formato inorgânico e suas misturas, mas não se limitam a estas.
