ABSTRACT:
A series of water-dispersible and oil-dispersible corrosion inhibiting solutions are disclosed which comprise about 10 ppm by volume to about 5% by volume of an acid catalyzed condensation reaction product of a fatty acid and a polythioether polyol represented by the formula: ##STR1## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are H, a methyl group, or an ethyl group, X is a divalent organic radical selected from the group consisting of --C.sub.2 H.sub.4 --, --C.sub.4 H.sub.8 --, --C.sub.2 C.sub.4 OC.sub.2 H.sub.4 --, and C.sub.2 H.sub.4 SC.sub.2 H.sub.4 --, and n is about 2 to about 40. Metal equipment can be protected through the use of the invention corrosion inhibiting solutions by contacting metal with an effective amount of inhibiting solution containing the polythioether polyol/fatty acid reaction product in a continuous exposure or batch treatment.
