The recovery of sulfolane from inorganic salts
Thread Content
I have a product for which sulfolane is used as a solvent. After the reaction, a large amount of inorganic salts are formed, and these salts contain significant amounts of sulfolane; even after centrifugation, the concentration of sulfolane remains high. Could experts advise on how to recover sulfolane from the solid materials? Thanks first.
First, if the mixture is a pure solution, distillation is used when there is a large difference in boiling points, while extraction is used when the difference is small
