Introduction | sodium octane sulfonate, white to off-white crystalline powder, sensitive to light. 1g of sodium octane sulfonate is soluble in 10ml of water. Octane sulfonate relative density (d204)1.015, melting point> 300 ℃, refractive index (n20D)1.3450, irritating. Sodium octane sulfonate is an essential special reagent for HPLC analysis. |
preparation | a method for preparation and purification of ion-pair chromatography reagent sodium octane sulfonate, comprising the following steps:(1) sulfonation: in a ML three-mouth bottle equipped with a cooling reflux device and mechanical stirring, add 126g of anhydrous sodium sulfite and 125 ml of water, add 1.2g of bromooctane and G of tetrapropylammonium bromide, and heat under reflux for 16 hours, until the reaction solution was clarified and not layered. (2) purification: the water in the reaction mixture is distilled off under reduced pressure at 85 ° C./20mmHg, the remaining solid is dried and pulverized, loaded into a Soxhlet extractor, and extracted with 1300ml of absolute ethanol, 162g of crude product was obtained, and then recrystallized from 2600ml of anhydrous ethanol, and the pure product was obtained after filtration. (2) drying: the purified product was placed in a vacuum drying oven and dried at 80 ° C./132 mmHg for 2 hours to obtain 61% G (yield: 99.6%) of a finished product with a content of>. |
