Background | in recent years, the output of lithium-ion batteries has grown rapidly and the application fields have been expanding, in 2010, the demand for lithium ion batteries was about 1.35 billion, which has become a high-tech product of great significance to the national economy and people's life in the 21st century. 1.3 propane sultone (PS) as the preparation of lithium ion secondary electrolyte basic functional additives, its purity directly affects the quality of the electrolyte, the current domestic market for the sale of PS, the purity of about 99.5%, not up to the battery level requirements (purity> 99.9%). |
preparation | (1) calcium chloride is dissolved in deionized water and stirred until the solid is dissolved, A calcium chloride solution with A mass concentration of 15% is prepared; Citric acid is added to the calcium chloride solution, and stirring is continued until the solid is dissolved to obtain A mixed solution A; Wherein the mass ratio of the calcium chloride to the citric acid is 5:0.3;(2) sodium polyacrylate was dissolved in deionized water and stirred to prepare A polyacrylic acid sodium solution with A mass concentration of 3%, which was slowly added to the mixed solution A prepared above, after the dropwise addition is completed, the mixture solution B is prepared by stirring for 30min under the condition of 3000 r/min; Wherein, the dropping acceleration of the sodium polyacrylate solution is 1mL/L; The mass ratio of sodium polyacrylate and calcium chloride is 0.1:1;(3) preparation of sodium carbonate solution with mass concentration of 20%, and then the above prepared mixed solution B is quickly added to the sodium carbonate solution, 5000 r/min of the state of stirring precipitation, after the completion of the precipitation, the precipitate was filtered, washed with deionized water, and dried to obtain porous calcium carbonate;(4) peroxybenzoic acid and deionized water were mixed and stirred at 50 ° C. Until the solid was dissolved, then the porous calcium carbonate was added, impregnated for 3H, then cooled to room temperature and dried to prepare a catalyst. The mass ratio of peroxybenzoic acid to porous calcium carbonate was 1:15;(5) the sodium allyl sulfonate and sulfuric acid solution were mixed into a three-necked flask, stirred at 1500 r/min stirring speed for 10min, and then the catalyst prepared above was added, Slowly raise the temperature to 80 ℃, stir the reaction for 1H, cool to room temperature after the reaction, add the ethanol solution of sodium hydroxide, stir and mix for 30min, then add hydrochloric acid to acidify, prepare 3-hydroxypropanesulfonic acid; wherein, the mass ratio of the sodium allylsulfonate and the catalyst is 10:1; In the ethanol solution of sodium hydroxide, the mass ratio of sodium hydroxide and ethanol is 5:15;(6) the 3-hydroxypropanesulfonic acid and n-hexane prepared above were mixed and added into a three-necked flask, and the reaction was stirred at 100 ° C. And 3000 r/min for 3H. After the reaction was completed, the reaction was cooled to room temperature and distilled under reduced pressure, the target product 1, 3-propane sultone was prepared. |
Chemical properties | colorless, odorless liquid. |
Use | sulfonating agent, widely used in pharmaceutical and chemical industry, photosensitive materials, lithium battery, biochemistry, textile, lubrication, wastewater treatment, surface treatment and other industries. It is used for the synthesis of leather, ink and sensitizing dyes. 1, 3-propanesulfonolactone is a new functional fine chemical material. It can react with many kinds of compounds under very mild conditions and accurately provide sulfonic acid groups, thus endowing these compounds with new properties. It is an excellent universal sulfonating agent, is also an important pharmaceutical intermediates, also used in brightening agents, dyes, double ionic surfactants, sulfonated antibacterial Synergist, combined with sulfa drugs to enhance antibacterial effect, also used for avian coccidiosis infection, intestinal bacterial infection; Drinking water agent 1, 3-propane sultone is a new functional fine chemical material. It can react with many kinds of compounds under very mild conditions and accurately provide sulfonic acid groups, thus endowing these compounds with new properties (such as hydrophilicity, antistatic and other characteristics), it is an excellent universal sulfonating agent and a key raw material for the synthesis of important electroplating additive intermediates PPS, UPS, DPS, MPS, ZPS, POPS, SP and other products. It is an important pharmaceutical intermediate and an important raw material for the production of lithium batteries. It is also used in brighteners, dyes, double ionic surfactants and sulfonating agents. It can also be used in lithium secondary batteries by itself to enhance the number of cycles and the service life of the battery. |
