方法一
Method 1
硫酸鉀法用硫酸銨和硫酸配制成電解液除雜質(zhì)后進(jìn)行電解。HSO4在陽(yáng)極放電而生成過(guò)二硫酸，再與硫酸銨反應(yīng)生成過(guò)硫酸銨，然后加入硫酸鉀進(jìn)行復(fù)分解反應(yīng)，經(jīng)冷卻、分離、結(jié)晶、干燥，制得過(guò)硫酸鉀成品。其
The potassium sulfate method uses ammonium sulfate and sulfuric acid to prepare an electrolyte for electrolysis after removing impurities. HSO4 is discharged at the anode to produce persulfate, and then reacts with ammonium sulfate to produce ammonium persulfate, then potassium sulfate is added for double decomposition reaction, and the finished product of potassium persulfate is prepared through cooling, separation, crystallization and drying. his
陽(yáng)極反應(yīng)：2HSO4-2e→H2S2O8
Anode reaction: 2hso4-2e → h2s2o8
陰極反應(yīng)：2H+2e→H2↑
Cathode reaction: 2h + 2e → H2 ↑
(NH4)2SO4+H2S2O8→(NH4)2S2O8+H2SO4
(NH4)2SO4+H2S2O8→(NH4)2S2O8+H2SO4
(NH4)2S2O8+K2SO4+H2SO4→K2S2O8+2NH4HSO4
(NH4)2S2O8+K2SO4+H2SO4→K2S2O8+2NH4HSO4
方法二
Method 2
由過(guò)硫酸銨與硫酸鉀進(jìn)行復(fù)分解反應(yīng)后，冷卻、分離、結(jié)晶、干燥而得。
It is obtained by double decomposition reaction of ammonium persulfate and potassium sulfate, cooling, separation, crystallization and drying.
過(guò)硫酸鉀用途
Application of potassium persulfate
過(guò)硫酸鉀可用作油井壓裂液的破膠劑。在合成樹(shù)脂、合成橡膠工業(yè)中作為乳液聚合的引發(fā)劑,用于丁二烯苯乙烯橡膠的合成;在照相業(yè)中用作硫代硫酸鈉的脫除劑;染料和印染工業(yè)中用作氧化劑;油脂工業(yè)中作漂白劑等。
Potassium persulfate can be used as gel breaker for oil well fracturing fluid. In the synthetic resin and synthetic rubber industry, it is used as initiator of emulsion polymerization for the synthesis of butadiene styrene rubber. Used as a remover of sodium thiosulfate in the photographic industry; Used as oxidant in dye and printing and dyeing industry; Used as bleaching agent in oil industry.
過(guò)硫酸鉀注意事項(xiàng)
Precautions for potassium persulfate
