Use of phosphonium compounds as corrosion inhibitors

Patent ·
OSTI ID:6048468

Phosphonium compounds and their uses are described. These corrosion inhibitors find special utility in the prevention of corrosion of pipe or equipment which is in contact with a corrosive oil-containing medium, as, for example, in oil wells producing corrosive oil or oil-brine mixtures, in waterfloods, in refineries, and the like. These inhibitors may, however, be used in other systems or applications. They appear to possess properties which impart to metals resistance to attack by a variety of corrosive agents, such as brines, weak inorganic acids, organic acids, COD2U, HD2US, etc. (10 claims)
