A corrosion inhibitor composition comprising:
- an Ammonium Iodide Ion Source, a first carbonyl containing compound having a general formula:
- and a second carbonyl containing compound having the general formula:
- wherein, the first carbonyl containing compound and the second carbonyl containing compounds are different, R1 is an alkyl or aromatic group, R2 is a hydrogen, alkyl or aromatic group, and R3 is a hydrogen or an alkyl group having from 1 to 6 carbons.
A corrosion inhibitor composition comprising:
- an Ammonium Iodide Ion Source, a first carbonyl containing compound selected from the group consisting of ethyl butyrate, cinnamaldehyde, benzaldehyde, and combinations thereof;
- and a second carbonyl containing compound selected from the group consisting of acetaldehyde, formaldehyde, and combinations thereof;
- and wherein the first carbonyl containing compound and the second carbonyl containing compounds are different.
