Patent ID: 7368051

Claim:
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 R 2 is OR 4 and R 3 is OR 5 , wherein R4 and R5 are selected from hydrogen and hydrocarbyl-OH and wherein at least one of R4 and R5 is hydrogen; or R 2 and R 3 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.
