  • Process for corrosion inhibiting composition in hydrocarbon fuels
    Patent number: 7368051
    Abstract: The present invention provides a process for the production of a fuel composition having a NACE corrosion rating of between 0% and 25%, comprising the steps of: (i) contacting a fuel with a corrosion inhibitor of formula (I) to provide an initial fuel composition wherein m and n are each independently an integer from 0 to 10; wherein R1 is an optionally substituted hydrocarbyl group; wherein either R2 is OR4 and R3 is OR5, wherein R4 and R5 are selected from hydrogen and hydrocarbyl-OH and wherein at least one of R4 and R5 is hydrogen; or R2 and R3 together represent —O—, and (ii) contacting the initial fuel composition with a caustic material to provide the fuel composition without subsequent addition of a corrosion inhibitor.
