Abstract

PURPOSE:To manufacture easily and inexpensively the titled corrosion inhibitor contg. no harmful substance and capable of perfectly preventing the corrosion of metal by gasification, by using the addition product of dicyclohexylamine to hydroxycarboxylic acid as an effective component. CONSTITUTION:The addition product of dicyclohexylamine to <=5C aliphatic hydroxycarboxylic acid or aromatic hydroxycarboxylic acid is packed into a bag or the like and used to prevent the corrosion of metal by gasification. Said corrosion inhibitor can be manufactured simply by adding dicyclohexylamine to hydroxycarboxylic acid by an equivalent mole to the mole of the carboxyl group and by stirring them while cooling from the outside to cause an addition reaction. Glycolic acid, lactic acid, malic acid, tartaric acid or salicylic acid is preferably used as the hydroxycarboxylic acid.
