摘要：NOVELTY - An extraction agent comprises hydrogen phosphate containing ionic liquids and/or hydrogen sulfate based ionic liquids, such as alkylimidazole cation and alkyl imidazolium cation having structure (I). USE - Extraction agent for use in seed oil extraction desulfurization application (claimed). ADVANTAGE - The agent has good desulfurization effect and can be reused, and is suitable in desulfurization application in simple and cost effective manner. DETAILED DESCRIPTION - An extraction agent comprises hydrogen phosphate containing ionic liquids and/or hydrogen sulfate based ionic liquids, such as alkylimidazole cation and alkyl imidazolium cation having structure of formula (I). R = 2-10C straight-chain or branched-chain alkyl group, preferably ethyl, butyl, hexyl, octyl or decyl. An INDEPENDENT CLAIM is also included for a sulfur-containing oil extraction desulfurization method, which involves utilziing extracting agent, and extracting desulfurization of oil.
