Sugar as an inhibitor of corrosion in canning

Corrosion Control with Organic Inhibitors

“…Levey (86) noted the higher inhibiting properties of crude quinaldine. De Whalley (57) reported that crude beet sugar had greater inhibiting properties than the refined sugar. Jimeno (38) observed the greater inhibiting efficiency of tannin over starch and Matthews (40) noted the formation of protective colloidal tannin films and the formation of black iron tannates.…”

Film Inhibitors in Industrials Aqueous Systems Effect of Chrome Glucosate in Aqueous Glucose Control Is as a Corrosion Inhibitor Where Oxygen Imparctical

“…The application of organic inhibitors on an industrial scale in aqueous systems has been delayed by lack of understanding of the protective mechanism and the effects of impurities in crude products. De Whalley (22) reported the greater inhibiting properties of crude beet sugar as compared to refined, and Levey ( 14) noted the higher inhibiting properties of crude quinaldine as compared to pure. Jimeno (IS) observed the greater inhibiting efficiency of tannin over starch, and Mat-in many industrial systems water is recirculated over cooling towers and similar devices so that the recurring air contact makes oxygen control impractical, if not impossible.…”
