Ammonium persulfate: tswakana le bohlokwa e sebetsang

ammonium persulfate e sebediswa ho matlafatsa tsamaiso e molekyler, hammoho le ho condense nakong ea ba lokisetsa ho ea rubbers, dipolasetiki le sika latex, ka ho nka lifoto, e mananose tsa mapolanka hatisitsoeng potoloho. boitsebiso boo ka linako tse ling o ile a sebelisa bakeng sa disinfection le kenngoa ka har'a sesoeufatsi.

Ammonium persulfate: thepa Physico-lik'hemik'hale

Himreaktiv emela lipoleiti colorless, ka linako tse ling le 'mala o botala. Hanyenyane qhibilihang ka har'a ho H 2 O (42.7%) ka mocheso oa 15,5 ° C. Nakong ea futhumatsang ka holimo ho likhato tse 120 liforomo pirosernisty ammonium, ha oksijene e lokolloa. Re lokela ho hlokomela hore letsoai ommeng ka ho bolokoa hoo e batlang e sa lekanyetsoang, ha letsoai le metsi ka potlako hydrolyzed le ho lokolloa ha oksijene le ea naetrojene. ditharollo ea metsi ya motsoako qala ho hydrolyze, esita le ka mocheso kamoreng, ha mocheso o phahama tshebetso disintegration e ntlafatsoa. E le hore a liehe li bole kapele, ho ditharollo ea metsi ya persulfate ammonium ile a phaella ka alum potassium kapa sulfates tsa tšepe a alkali.

Ammonium persulfate: go tswakana ya

A tharollo reagent e lokisitsoeng ke electrolysis tsa sulphate ammonium ka acid e sulphate. Ho etsa sena, nka e le nkho 20 cm, le bophara ba le bophahamo ba modumo ea a etsang dilitara tse peli e tšela ho eona 1,7 litha e le nngwe ya phelelang tharollo ammonium sulfate le dimililitha tse hlano tsa acid e sa sulphate. Ka mor'a moo, motsoako sephetho ile ea behoa tlas'a electrolysis sebelisa li-electrode entsoe ka polatinamo terata. Ha ba ntse ba tsoela electrolysis qala ho nkha ea hydroxide ammonium, ka nako eo eketsa di ml tse tharo ho tse hlano ba ka tharollo phelelang tsa sulphate ammonium ka sulfate acid e. Ka mor'a mong le e mong lihora tse tharo ho isa ho tse 'nè le felisoa theoha li-electrode jwale. Ka mor'a lihora tse 24 electrolysis ile eketsa 90 g ya sulfate e sithabetseng ammonium le electrolysis ea tsoela pele ka lihora tse seng 70. Nakong ea tharollo electrolysis e susumelletsa kamehla. The lithollo sephetho sa persulfate ammonium ile arohane le tharollo e hape batho ba phelelang ho sulphate ammonium le asiti sulphate acidified. The precipitate sephetho le e omisitsoeng ka mocheso e se phahameng ho feta likhato tse 40.

E le busa, o ile a fumana ho latela itse mokhoa oa ho lokisetsa e na le se fetang 90% ammonium nadsernistogo, e atisa ho sebelisoa e le oxidant e. A reagent le ea mahloriso e ka tlaase ea dintho a sebetsang a amenable ho recrystallization. Ho e 700 g ya letsoai qhalwa ho ya ka e bophahamo ba modumo le tsoanang ea metsi a futhumetseng (ka bang 40 ° C). Ho ekelletsa moo, ho sebelisa fluted filtara pampiri, teko tharollo e tlhotliloeng bacha, eaba e filtrate e folisoa. The lithollo sephetho ne a hloekisa persulfate ammonium tlhotliloeng ka Buchner funnel le hlatsoa ka metsi. Ho lokisetsa a fumana ke ka kakaretso kopana litšoaneleho reagents q.s.p.

Ammonium persulfate - phatloha le mollo bopaki, empa thusa hore ho combustion ea lintho tse ling. Ka tshebetso ya ho tukang theoha dintho tena le nang le chefo e. Iteanya itse reagent le dintho combustible hoa lumelloa, e le ho amana le oxidant matla le a leka ka lintho tse bonahalang combustible, hammoho le ho fokotsa likokoana-hloko. Nakong ea futhumatsang persulphate ammonium bola ka potlako, ena chelete e ngata likhase tse chefo le senyang (oxides naetrojene, ammonia mouoane, oxides sebabole). Tekanyo ea hore o susumetse ka 'mele oa motho ke e' ngoe ea lintho tse sa sehlopha sa boraro a le kotsing. Palo e kahodimodimo mameletse lethal dose ka sebakeng sebetsa bakeng sa persulfate ea ammonium ke 0,1 mg, ka ho ya ka mitha dikhubu.

ammonium persulfate bontša le phello tena ka letlalo le lera la mucous tsa nasal e, molomo cavity, pampitšana matšoafo, conjunctiva. Inhalation tsa ntho e qholotsa ntshetsopele ya lefu asthmatic. Ha nako e telele kapa a pheta ho ikopanya etsahala dermatitis, eczema, hangata a tsamaea le kulisa, o ile a bontša ka urticaria le makala.

Ha ho sebetsa le reagent hlokahala ho sebelisa mefuta e fapaneng ya thepa ea botho sireletsang (respirator, goggles rabara, overalls).
