| 发明名称 | Method for purifying 2-fluorobutane | ||
| 摘要 | The present invention is a method for 2-fluorobutane to obtain highly purified 2-fluorobutane through a process comprising a step for: bringing crude 2-fluorobutane that includes 5 to 50 wt % of butene into contact with a brominating agent that can form a bromonium ion in an aprotic polar solvent in the presence of water or an alcohol having up to 4 carbon atoms; converting the butene into compounds having a boiling point higher than that of 2-fluorobutane, then recovering 2-fluorbutane from the reaction solution; and purifying the recovered 2-fluorabutane by distillation. | ||

| 主权项 | 1. A conversion method comprising bringing crude 2-fluorobutane that includes 5 to 50 wt % of butene into contact with a brominating agent that can form a bromonium ion in an aprotic polar solvent in the presence of water or an alcohol having up to 4 carbon atoms to convert the butene into bromine containing compounds having a boiling point higher than that of 2-fluorobutane. | ||
