Title: Improvements in or relating to corrosion inhibition
IPC: C23F11/14
Filed: 1950-04-27
Abstract: A composition for use as a corrosion inhibitor for ferrous metals comprises the product of the reaction at a temperature p substantially below the boiling point of water of an amine and an "acidic chromate compound," i.e. a compound such as a chromic acid, an alkali metal dichromate or polychromate which in aqueous solution has a pH less than 7.  An aqueous solution containing 10 per cent potassium dichromate may have a primary, secondary or tertiary amine added thereto equivalent to at least twice the molar ratio, preferably at about 60-100 DEG  F.  A colour change, from orange to yellow with potassium dichromate, indicates completion of the reaction.  The product may be recovered by evaporation.  Numerous examples of amines are given including such mixed amines as melamine, diazines, and triazines.  Reaction products of cyclohexylamine, aniline, diethanolamine, triethylamine and aminoethylethanolamine with potassium dichromate are used to indicate the inhibiting effect on the corrosion of steel by water saturated with oxygen, carbon dioxide or hydrogen sulphide.  The process is applicable to corrosion prevention in petroleum refineries, storage and transportation of petroleum products, oil and gas wells.  The inhibitor is generally added in an amount of 5-500 parts per million of the corrosive solution.
