Abstract
⺠Amino acid based ionic liquids can be used to remove naphthenic acids from crude oil. ⺠Both reactive and physical extraction reduces the total acid number. ⺠The reaction mechanism involves the formation of a zwitterionic species. ⺠The zwitterionic species can be reacted with carbonic acid to reform the ionic liquid. ⺠Successful multistage recycling of the ionic liquid has been demonstrated.
