Ammonium persulfate: kuyondelelaniswe nokubaluleka practical

ammonium persulfate isetyenziselwa ukuqinisa inkqubo polymerization, kwakunye ngamafuphi ngexesha lamalungiselelo rubbers, iplastiki kunye latex, kufota, xa ngasekhohlo of iibhodi beesekethe eprintiweyo. Le nto maxa wambi kusetyenziswa kweentsholongwane kwaye mhlophe.

Ammonium persulfate: iipropati Physico-chemical

Himreaktiv imele iipleyiti enemibala emihle, ngamanye amaxesha kunye nombala oluhlaza. Kancinane enyibilikayo H 2 Owu (42.7%) xa amaqondo obushushu 15,5 ° C. Ngexesha amalahle ngaphezu kweqondo 120 Iifom Ammonium pirosernisty, ngelixa mpilo kukhululwa. Kufuneka kuqatshelwe ukuba ityuwa owomileyo kunokugcinwa phantse ngokungenammiselo, lo gama ityuwa emanzi hydrolyzed ngokukhawuleza kunye ukukhululwa oksijini nitrogen. izisombululo zolwelo le compound aqale hydrolyze, nokuba bushushu, xa ubushushu inkqubo sokonakalisa zinokukhuliswa. Ukuze ukwehlisa le ukonakala, ukuba izisombululo zolwelo ze ammonium persulfate zafakwa potassium alum okanye sulfates zesinyithi kwealkali.

Ammonium persulfate: Synthesis

Isisombululo reagent ilungisiwe yi electrolysis ezintlanu ze ammonium sulphate kwi acid sulphate. Ukuze wenze oku, thatha ingqayi 20 cm ubukhulu kunye nomthamo neelitha ezimbini obuphalazelwe kuyo 1.7 ilitha sisombululo ammonium sulfate isinyibiliko ngeemililitha ezintlanu esidi sulphate. Okulandelayo, umxube kubangele yathotyelwa electrolysis usebenzisa electrode ezenziwe wire platinum. Ukuba inkqubo electrolysis iqala ukuba asijoje ammonium hayidroksayidi, uze udibanise ml ezintathu ukuya ezintlanu umxube ezintlanu ze ammonium sulphate kwi sulfate asidi. Emva kweeyure ezintathu ukuya kwezine zonke, wazisula off electrode yangoku. Emva kweeyure 24 electrolysis zafakwa 90 g batyumkileyo ammonium sulfate kunye electrolysis kwaqhubeka omnye iiyure ezingama-70. Ngexesha isisombululo electrolysis athe agxojwa gxojwa rhoqo. Le ziikristale kweziphumo ammonium persulfate wahlulelwa kwaye isisombululo kwakhona okroqiweyo ammonium sulphate kunye sulphate asidi muncu. Le kwenze ngenxa yomile kwiqondo lobushushu hayi ngaphezulu kwe 40.

Njengomgaqo, wafumana ngenxa uthe indlela yokulungiselela iqulethe hayi ngaphezulu kwe-90% ammonium nadsernistogo, yona isoloko isetyenziswa oxidant. A reagent nge xi esezantsi kwezinto esebenzayo iSADC recrystallization. Ukuze kuyo 700 g yetyuwa ixutywe umqulu twatse wamanzi ashushu (40 ° C). Ngaphezu koko, esebenzisa iphepha filter iintsika, umxube uvavanyo ecociweyo ebezikuyo filtrate lupholisiwe. Le ziikristale kuphumela njengamntu ammonium persulfate kuhluzeka kwi ifanele Buchner ihlanjwe ngamanzi. Amalungiselelo endibufumeneyo ngokubanzi uyahlangabezana iziqinisekiso wezenzi q.s.p.

Ammonium persulfate - Explosion nomlilo nobungqina, kodwa negalelo ukutshiswa nezinye izinto. Kwinkqubo wokutshisa off izinto kucaphukisa ityhefu. Ukuqhagamshelana uthe reagent kunye izinto ezinokutsha akuvumelekanga, njengoko inxulumene oxidant esomeleleyo idityaniswe izinto ezinokutsha, kwakunye arhente yokunciphisa. Ngexesha ubilisa ammonium persulphate ubola ngokukhawuleza, oku ivelisa emininzi imimoya enetyhefu onakalisayo (kwenitrojeni, ammonia umphunga, nesalfure oxides). The degree of nempembelelo emzimbeni womntu yenye izinto kwiklasi yesithathu ingozi. umthamo sihambisane obukhulu kwindawo yokusebenza ye kuba persulfate Ammonium yi 0.1 mg nge-cubic meter.

ammonium persulfate ukubonisa nempembelelo ukubacaphukisa kwisikhumba kunye kwiinwebu ngeempumlo, kwisisu ngomlomo, iphecana yokuphefumla, conjunctiva. Inhalation osisiqu kuphakamisa ukuphuhliswa sifo somoya. Xa eside okanye umfowunelwa ngokuphindaphindiweyo zenzeka dermatitis, nangokhwekhwe, ngokufuthi ephelekwa negazi, ebonakalaliswe njengoko urticaria kunye nokothuka.

Xa sisebenza kunye reagent kuyimfuneko ukusebenzisa iintlobo izixhobo siqu (baphefumla, izibuko irabha, ovaroli).
