摘要

The present invention relates to compounds which inhibit corrosion of metals which are not toxic and biodegradable, said compounds being of the salts obtained by reaction between a dicarboxylic acid and a derivative of imidazoline. The present invention also relates to the use of these compounds, corrosion inhibitors in any type of industry of ores or compounds, fossil, such as the gas or petroleum.
