| titleOfInvention | Preparation method of 1-fluoro-1, 3-propane sultone |
| abstract | The invention provides a preparation method of 1-fluoro-1, 3-propane sultone, which comprises the following steps: 1) reacting 3-allyl halide with bisulfite under the action of an initiator to generate 1-bromo-3-hydroxypropanesulfonic acid salt, and 2) acidifying to obtain 1-bromo-3-hydroxypropanesulfonic acid; 3) carrying out rotary evaporation and dehydration on the product obtained in the step 2), and then carrying out high-temperature rectification to obtain 1-bromo-1, 3-propane sultone; 4) dissolving the rectification product obtained in the step 3) by using a solvent, and then adding a fluorinating agent for carrying out a fluorination reaction to obtain 1-fluoro-1, 3-propane sultone, wherein the 1-fluoro-1, 3-propane sultone prepared by the invention can be used as an intermediate and a sulfonating agent, is mainly used as an additive of lithium battery electrolyte, and particularly can be widely applied to the high-voltage field of lithium ion batteries because the fluorine element exists, and the battery voltage can be improved. |
