Neoacid corrosion inhibitors

摘要

composition and method relating to organic acid corrosion inhibitors for use in antifreeze coolant compositions. The corrosion inhibitors comprise a C8 mono-carboxylic acid component, or isomers and/or salts thereof, and a neo-decanoic acid, or isomers and/or salts thereof. The corrosion inhibitors claimed provide improved corrosion protection to metal surfaces as compared to conventional inhibitors and provide improved corrosion protection as compared to inhibitors containing only a single mono-carboxylic acid component. Also included is an antifreeze coolant concentrate comprising said corrosion inhibitor.
