Abstract

"INIBIDOR DE CORROSãO DE IMIDAZOLINA, E, PROCESSO PARA INIBIçãO DE CORROSãO EM LINHAS METáLICAS". Esta invenção fornece uma série de novos inibidores de corrosão de imidazolina acrilada substituída de fórmula (I) em que R~ 1~ é um radical alquila que tem desde 2 até 8 átomos de carbono; R~ 2~ é um radical derivado de um ácido graxo e R~ 3~ é um radical derivado de um ácido insaturado e um processo para inibição de corrosão em linhas de escoamento de metal através da introdução de tais inibidores em um sistema em que se pede que a corrosão seja impedida.
