Hydrogen Sulfide (H2S)

Litekanyetso tsa tekheniki

Hydrogen sulfide ke motsoako oa inorganic o nang le foromo ea molek'hule ea H2S le boima ba molek'hule ba 34.076.Tlas'a maemo a tloaelehileng, ke khase ea asiti e tukang.Ha e na 'mala ebile e na le monko oa mahe a bolileng maemong a tlase.chefo.Tharollo ea metsi ke hydrogen sulfuric acid, e fokolang ho feta carbonic acid, empa e matla ho feta boric acid.Hydrogen sulfide e qhibiliha ka metsing, e qhibiliha habonolo ka har'a lino tse tahang, metsoako ea petroleum le oli e tala, 'me lik'hemik'hale tsa eona ha lia tsitsa.Hydrogen sulfide ke k'hemik'hale e tukang le e kotsi.Ha e kopane le moea, e ka etsa motsoako o phatlohang.E ka baka mollo le ho phatloha ha e pepesehetse malakabe a bulehileng le mocheso o phahameng.Hape ke ntho e matla le e chefo haholo.Hydrogen sulfide e tlaase-concentration e na le liphello mahlong, tsamaiso ea ho hema le tsamaiso ea methapo e bohareng.Ho hema moea o monyenyane oa hydrogen sulfide e phahameng haholo ho ka bolaea ka nako e khutšoanyane.E sebelisoa ha ho etsoa li-phosphors, electroluminescence, photoconductors, photoelectric exposure metres, joalo-joalo. Organic synthesis reduction agent.E sebelisetsoa ho hloekisa tšepe, chefo e bolaeang likokoanyana, meriana, nchafatso ea catalyst.Li-reagents tse akaretsang.Tokisetso ea li-sulfide tse fapaneng.E sebelisoa ha ho etsoa li-sulfide tsa inorganic, hape e sebelisoa tlhahlobong ea lik'hemik'hale joalo ka ho tsebahatsa li-ion tsa tšepe.High-purity hydrogen sulfide e sebelisoa semiconductor le masimong a mang.E ka boela ea sebelisoa indastering ea lik'hemik'hale ea ts'ireletso ea naha, li-intermediates tsa meriana le chefo e bolaeang likokoanyana, ho hloekisa tšepe e sa sebelisetsoeng tšepe le phekolo ea ho fetola bokaholimo ba tšepe, e sebelisoang ho lokiseng khase e tloaelehileng, khase ea calibration, le tlhahlobo ea lik'hemik'hale tse kang ho khetholla li-ion tsa tšepe.Ntho ea bohlokoa e tala bakeng sa ho etsa thepa ea infrared optical.Litlhokomelo tsa polokelo: Boloka sebakeng sa polokelo se pholileng, se nang le moea o pholileng.E-ba hōle le mehloli ea mollo le mocheso.Mocheso oa polokelo ha oa lokela ho feta 30°C.Boloka setshelo se koetsoe ka thata.E lokela ho bolokoa ka thoko ho li-oxidants le alkalis, 'me u qobe polokelo e tsoakiloeng.Sebelisa mabone a thibelang ho phatloha le lisebelisoa tsa moea.Ho thibetsoe ho sebelisa lisebelisoa tsa mechine le lisebelisoa tse atisang ho ba le litlhase.Sebaka sa polokelo se lokela ho ba le lisebelisoa tsa phekolo ea tšohanyetso tse lutlang.

Kopo:

① Tlhahiso ea metsoako ea thioorganic:

Metsoako e mengata ea organosulfur e hlahisoa ka hydrogen sulfide.Tsena li kenyelletsa methanethiol, ethanethiol, le thioglycolic acid.

②Analytical chemistry:

Ka lilemo tse fetang lekholo, hydrogen sulfide e ne e le ea bohlokoa k'hemistri ea tlhahlobo, tlhahlobong ea boleng ba li-ion tsa tšepe.

③Selelekela sa sulfide ea tšepe:

Joalokaha ho bontšitsoe ka holimo, li-ion tse ngata tsa tšepe li itšoara ka hydrogen sulfide ho fana ka sulfide ea tšepe e tšoanang.

④Lisebelisoa tse fapaneng:

Hydrogen sulfide e sebelisoa ho arola deuterium oxide, kapa metsi a boima, ho tloha metsing a tloaelehileng ka mokhoa oa Girdler sulfide.

Sephutheloana se tloaelehileng:

①Bohloeki bo phahameng, setsi sa morao-rao;

② moetsi oa setifikeiti sa ISO;

③Polelo e potlakileng;

④Thepa e tsitsitseng e tsoang ho phepelo ea kahare;

⑤Sistimi ea tlhahlobo ea marang-rang bakeng sa taolo ea boleng mohatong o mong le o mong;

⑥Tlhaho e phahameng le ts'ebetso e hlokolosi ea ho sebetsana le silinda pele e tlatsa;
