| Abstract: | N-formylmorpholine(NFM) is an excellent extractive distillation solvent with outstanding thermal and chemical stability,good regeneration performance and extraction selectivity,and lower toxicity and corrosivity.The application of NFM as a solvent in coking crude benzene extractive distillation refining processes was described.Qualities of the NFM products produced by two different process routes,formic acid method and methyl formate method,were analyzed and compared.The NFM product from methyl formate method has better quality and is more suitable to be used in the coking crude benzene refining processes. |
