Title:
CORROSION INHIBITOR COMPOSITIONS, METHODS FOR MAKING AND METHODS FOR USING
Document Type and Number:
WIPO Patent Application WO/2013/169439
Kind Code:
A3
Abstract:
A method for inhibiting corrosion on metallic surfaces in contact with a liquid hydrocarbon media is provided. A corrosion inhibitor composition is dispersed into a liquid hydrocarbon media to form a protective film on the metallic surfaces. The corrosion inhibitor includes a polyamic acid having structure I:(Formula I) or structure ΙI:(Formula II) wherein A has structure III:(Formula III) and R is a (C8-C22) alkyl group or a (Cg-C22) alkenyl group, x is an integer from 0 to 6 and n is an integer from 1 to 6. A method for preparing the corrosion inhibitor is also provided.
