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 (I) wherein m and n are each independently an integer from o 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.

La présente invention concerne un procédé de production d'une composition de combustible présentant un niveau de corrosion NACE comprise entre 0 % et 25 %. Ledit procédé consiste: (i) à mettre en contact un combustible avec un inhibiteur de corrosion de formule (I) afin d'obtenir une composition de combustible initiale (I) dans laquelle m et n représentent chacun indépendamment un entier compris entre 0 et 10 ; R¿1? représentant un groupe hydrocarbyle éventuellement substitué; R¿2? représentant OR¿4? et R¿3? représentant OR¿5?, R¿4? et R¿5? étant sélectionnés parmi hydrogène et hydrocarbyl-OH et R¿4? et/ou R¿5? représentant hydrogène; ou R¿2? et R¿3? représentant ensemble ?___¿o?___¿, et (ii) à mettre en contact la composition de combustible initiale avec une matière caustique afin d'obtenir la composition de combustible sans addition ultérieure d'un inhibiteur de corrosion.
