Application of sulfolane
Application 1: It is used for natural gas purification and desulfurization, aromatics extraction of reformate oil, and removal of carbon dioxide, hydrogen sulfide, organic sulfur and other impurities in hydrogen.
Use 2: It is used as gas chromatography stationary liquid and analytical reagent, and also for organic synthesis.
Use 3: polar solvent with strong solubility and good selectivity. Most organic compounds and polymers can be soluble in or miscible with sulfolane. It is mainly used as extractant for aromatics extraction, polymer spinning or casting solvent, purification of natural gas, synthesis gas, refinery gas, purification and desulfurization of synthesis gas, and as solvent for rubber and plastics. In addition, it can also be used in textile printing and dyeing industry as printing and dyeing auxiliaries, which can make colors bright and bright.
Preparation method of sulfolane
Methods: Butadiene and sulfur dioxide were used as raw materials, and the sulfolane solution was synthesized by heating in a pressure resistant reactor (100-110 ℃) in the presence of hydroquinone solvent. After fractionation, the refined sulfolane was hydrogenated into sulfolane in the presence of nickel containing catalyst, and then the finished product was obtained after gas-liquid separation and fractionation. Raw material consumption quota: butadiene (>99%) 654kg/t, sulfur dioxide (>97%) 909kg/t, aluminum nickel catalyst (Ni45-50%) 71kg/t, liquid * * * 110kg/t.
