Abstract
The corrosion of ferrous metals by corrosive acids at elevated temperatures is inhibited by adding to environments containing the acids an effective amount of a novel .alpha., .OMEGA. (hereinafter 'alpha', 'omega', respectively) diacetylenic diol (e.g., with two acetylenic functionalities) having the structural formula: ##STR1## where R is an aliphatic, alicyclic or aromatic residue containing from 1 to about 12 carbon atoms and may include one or more functional groups such as halogen atoms, carbonyl, carboxyl, carbamyl, amino, formyl or nitroso radicals or other functional groups without impaired performance. The diacetylenic diols may be employed in combination with other corrosion inhibitors.
