A process for deacidifying a crude oil and/or crude oil distillate containing organic acids comprising the steps of:
(a) contacting the crude oil and/or crude oil distillate containing organic acids with a basic ionic liquid having a melting point of below 150°C, and extracting at least a portion of the organic acids into the basic ionic liquid as an extract phase; and
(b) separating a crude oil and/or crude oil distillate phase which is reduced in acidity from the basic ionic liquid extract phase.
