Title:
METHOD FOR INHIBITING CORROSION USING CERTAIN PHOSPHORUS AND SULFUR-FREE AROMATIC COMPOUNDS
Document Type and Number:
WIPO Patent Application WO2003006581
Kind Code:
A3
Abstract:
The persent invention relates to a method for inhibiting corrosion of corrosion-prone metal surfaces by organic acid-containing petroleum streams by providing an effective corrosion-inhibiting amount of sulfur and phosphorus-free aromatic compounds substitutedwith nitrogen,containing functional groups at the 5- or 3, 5-position, typically up to 1000 wppm, to the metal surface.
