| Abstract: | The refinery byproduct raw naphthenic acid was condenced with triethylenetetramine to produces an oilsoluble intermediate of cycloalkyl imidazoline, and then it was transformed into watersoluble corrosion inhibitor of cycloalkyl imidazolinequaternaryammoniumsalt by diemethyl sulfate. Some factors such as the type of amine, the mole ratio of amine to acid, and the quantity of solvent affecting the anticorrosive capacity of the inhibitor were discussed. Its anticorrosive performance was studied by the menthods of loss of weight and polarization curve. |
