| titleOfInvention | Corrosion inhibitors |
| abstract | In general the current invention relates to corrosion inhibitors useful in water-based (aqueous) heat transfer fluids. More particularly, the present invention can be used for protecting ferrous and non-ferrous metal surfaces used in the construction of water-based (aqueous) heat transfer systems such as engine blocks and radiators. The invention particularly applies to a blend of corrosion inhibiting agents that can be added to water or water-glycol or other suitable liquid in a circulating or static heat transfer system to protect metal surfaces from corrosion attack. When used in an aqueous solution the unique blend of corrosion inhibiting agents provides flash corrosion protection of ferrous and non-ferrous surfaces during operation and after the treated aqueous fluid is drained away provides atmospheric corrosion protection of the ferrous and non-ferrous surfaces. The invention further relates to a variety of other practical and industrial applications such as engine coolant corrosion inhibition, dyno fluid corrosion inhibition, and metal working corrosion inhibition applications. The corrosion inhibitor includes several components 1) a dicarboxylic acid component comprising decanedoic and dodecanedoic and one or more C10-C12 dicarboxylic acids or salts of these acids, 2) an oxyalkylated carboxylate imidazoline preferably produced from carboxylate fatty acid and amine, 3) organophosphonic acid or amine salts of the organophosphonic acid and 4) a secondary or tertiary alkanolamine organic acid salting agent. The corrosion inhibitors of the present invention provide improved corrosion protection as compared to conventional inhibitors and provide surprisingly improved corrosion protection as compared to inhibitors containing only a single mono-carboxylic acid or blend of monocarboxylic and dicarboxylic acids or salts of these acids. The corrosion inhibitor of the present invention preferably contains no nitrite, nitrate, or silicate salts. |
