1.Litšobotsi le Matlotlo a Sodium Hydrosulfide

Mefuta ea Lik'hemik'hale

Sodium hydrosulfide ke motheo o matla o qhibilihang haholo metsing mme o haelloa ka potlako ho hlahisa khase ea hydrogen sulfide (H₂S). E ka arabela le li-ion tse ngata tsa tšepe ho theha li-precipitate kapa litharollo tse tsamaellanang tsa sulfide. Sodium hydrosulfide e ka boela ea feta liketsong tsa phetolo le metsoako e itseng ea lintho tse phelang, joalo ka phetolo ea electrophilic, acyl chloride amidation, le liketso tsa phokotso le metsoako ea Carbon yl e tletseng. Ho feta moo, Sodium Hydrosulfide e ka oxidizetsoa ke li-oxidizing agents ho etsa sodium sulfate.

Matlo a 'mele

Sodium hydrosulfide e hlaha e le phofo e se nang 'mala kapa phofo ea kristale 'me e batla e tsitsitse mocheso oa kamore. Ha e qhibilihe hantle ka har'a metsoako ea lintho tse phelang, empa ha e qhibiliha ka metsing, e hlahisa motsoako oa alkaline. Sodium hydrosulfide e na le sets'oants'o se batlang se phahame, 'me sebaka sa ho qhibiliha se ka bang 350°C. Sebopeho sa eona sa phofo se na le monko o ikhethang oa lehe le bolileng, o bakoang ke khase ea hydrogen sulfide e hlahisoang holim'a hydrolysis.

Botsitso ba Lik'hemik'hale

Sodium hydrosulfide e batla e tsitsitse mochesong oa kamore 'me e ka bolokoa nako e telele sebakeng se omileng. Leha ho le joalo, e batla e utloa mongobo 'me e khona ho monya metsi habonolo, e leng se lebisang ho senyeha. Ho feta moo, sodium hydrosulfide e ka hlaseloa habonolo ke oxidation ka li-oxidizing agents moeeng, e leng se etsang hore ho thehoe sodium sulfate.

Safety

Sodium hydrosulfide e na le boemo bo itseng ba chefo, haholo-holo ka lebaka la khase ea hydrogen sulfide e hlahisoang holim'a hydrolysis, e ka halefisang le ho senya tsamaiso ea ho hema le ea methapo. Ka hona, ho lokela ho nkoa mehato ea ho qoba ho hema khase ea hydrogen sulfide ha ho sebelisoa sodium hydrosulfide. E boetse e senya, 'me ho kopana le letlalo le mahlo ho lokela ho lateloa ke ho hlatsoa hang-hang ka metsi a mangata. Mehato e nepahetseng ea ts'ireletso, joalo ka ho roala liatlana le li-respirators, e lokela ho sebelisoa nakong ea polokelo le ho ts'oaroa.

dikopo

Sodium hydrosulfide e na le lisebelisoa tse ngata tse fapaneng tsa indasteri. E sebelisoa e le ntho e fokotsang indastering ea sulfurization, hangata bakeng sa ho hloekisa tšepe, motsoako oa meriana, ho ntšoa ha masimo a oli, ho hloekisa metsi a litšila le ho hloekisa holim'a litšepe. Sodium hydrosulfide e boetse e sebelisoa e le sesebelisoa sa tlhahlobo bakeng sa ho bona li-ion tsa tšepe kapa li-sulfide ka har'a metsoako ea lintho tse phelang. Ho feta moo, e bapala karolo ea bohlokoa indastering ea silicone e le sesebelisoa sa ho kopanya silane kapa e le ntho e senyang tlhahiso ea rabara ea silicone.

Summary

Ka kakaretso, sodium hydrosulfide ke motsoako o sebetsang oa inorganic o khetholloang ke alkalinity e matla, ho qhibiliha ho holimo metsing, le ho hlahisa khase ea hydrogen sulfide. Libaka tsa eona tsa mantlha tsa ts'ebeliso li kenyelletsa tlhoekiso ea tšepe, motsoako oa meriana, kalafo ea metsi a litšila le chemistry ea tlhahlobo. Ha o sebelisa sodium hydrosulfide, mehato e nepahetseng ea ts'ireletso e lokela ho nkoa ho qoba ho kopana le sehlahisoa sa eona sa hydrolysis, khase ea hydrogen sulfide, le ho etsa bonnete ba hore mekhoa e bolokehileng ea ho boloka le ho sebetsana le eona.

2.Mekhoa e Tloaelehileng ea ho Fumana Sodium Hydrosulfide

Tlhahlobo ea Ponahalo

Tlhahlobo ea ponahalo e ka etsoa ka ho shebella ka ho toba sampole ea sodium hydrosulfide, ho kenyelletsa le 'mala oa eona, sebōpeho le boholo ba likaroloana bakeng sa tlhahlobo ea pele.

Teko ea Thepa

Teko ea thepa e ka etsoa ka ho fofonela sampuli ho fumana hore na ho na le monko o hlakileng oa hydrogen sulfide.

Bohloeki Testing

Mekhoa e tloaelehileng ea tlhahlobo ea bohloeki e kenyelletsa chromatography ea khase, homogeneous titration, ion chromatography, le molecular photometry. Har'a tsena, chromatography ea khase e ka arola le ho lekanya litšila ka sodium hydrosulfide, e lumellang ho baloa ha bohloeki.

Teko ea Mongobo

Mekhoa e tloaelehileng ea ho lemoha mongobo e kenyelletsa mokhoa oa ho omisa le mokhoa oa Karl Fischer. Mokhoa oa ho omisa o kenyelletsa ho futhumatsa boima bo itseng ba sodium hydrosulfide ka mocheso o itseng, ho e lekanya, le ho futhumatsa khafetsa le ho lekanya ho fihlela boima bo tsitsitseng bo finyelloa. Joale mongobo o baloa ho latela tahlehelo ea boima ba 'mele. Mokhoa oa Karl Fischer o etsa qeto ea boemo ba mongobo ka ho lekanya boholo ba carbon dioxide e hlahisoang ha sampole e arabela le reagent ea Karl Fischer.

Teko ea Tšilafalo ea Lik'hemik'hale

Litšila tsa lik'hemik'hale ho sodium hydrosulfide li ka bonoa ho sebelisoa mekhoa ea ho lekanya mahloriso. Mohlala, li-ion tsa chloride li ka bonoa ka mokhoa oa silevera oa bromide kapa mokhoa oa koporo ea sulfate.

3.Outlook bakeng sa Sodium Hydrosulfide Lefapheng la Lik'hemik'hale

Nakong e tlang, ha tlhokomeliso ea ts'ireletso ea tikoloho e ntse e eketseha, tlhoko ea mahlale a ho hloekisa metsi a litšila e tla eketseha haholo. Sodium hydrosulfide, e le sesebelisoa sa lik'hemik'hale se sebelisoang haholo ho hloekisa metsi a litšila, e tla tsoela pele ho fumana tlhokomelo le tšebeliso. Ntle le moo, ka tsoelo-pele ea mahlale a indasteri, mekhoa ea ho hlahisa sodium hydrosulfide e lebelletsoe ho sebetsa hantle le ho baballa tikoloho, ka hona e matlafatsa ts'ebetso ea eona ea moruo le botsitso.

Ho feta moo, ka tsoelo-pele e tsoelang pele ea lisebelisoa le mahlale a macha, ts'ebeliso ea sodium hydrosulfide le eona e tla atoloha libakeng tse ling. Mohlala, lekaleng la matla, sodium hydrosulfide e ka sebelisoa ho lokisa lisebelisoa tsa polokelo ea matla, e nolofalletsang tšebeliso e nepahetseng le ho boloka matla. Lefapheng la elektronike, sodium hydrosulfide e ka sebetsa e le moemeli oa ho fokotsa ho hanyetsa ho ntlafatsa conductivity ea likarolo tsa elektronike. Lipatlisiso tse ling le nts'etsopele ea likopo tsena li ntse li hlokahala.

Ka kakaretso, sodium hydrosulfide e na le mefuta e mengata ea lits'ebetso indastering ea lik'hemik'hale, ho kenyeletsoa joalo ka moemeli oa vulcanizing, moemeli oa kalafo ea metsi a litšila, le organic synthesis reagent. Ka tlhokomeliso e ntseng e eketseha ea ts'ireletso ea tikoloho le ho hlaha ha lisebelisoa le mahlale a macha, litebello tsa ts'ebeliso ea sodium hydrosulfide li ts'episa haholo. Re na le lebaka la ho lumela hore ts'ebeliso ea sodium hydrosulfide e tla tsoela pele ho hola le ho bapala karolo e kholo indastering ea lik'hemik'hale nakong e tlang.
