Abstract
This invention relates to the use of phosphorylated oxyalkylated polyols (POP) in conjunction with sulfite oxygen scavengers in inhibiting corrosion in oxygen-containing systems. The phosphorylated oxyalkylated polyols are effective in inhibiting the precipitation of the sulfite and bisulfite oxygen scavengers as scale.
