IHydrogen Sulfidi (H2S)

Imingcele yezobuchwepheshe

I-Hydrogen sulfide iyinhlanganisela ye-inorganic ene-molecular formula ye-H2S kanye nesisindo samangqamuzana angu-34.076. Ngaphansi kwezimo ezijwayelekile, iyigesi ye-asidi evuthayo. Ayinambala futhi inephunga lamaqanda abolile ezindaweni eziphansi. ubuthi. Isixazululo esinamanzi yi-hydrogen sulfuric acid, ebuthakathaka kune-carbonic acid, kodwa inamandla kune-boric acid. IHydrogen sulfide iyancibilika emanzini, incibilika kalula otshwaleni, izincibilikisi ze-petroleum namafutha aluhlaza, futhi izakhiwo zayo zamakhemikhali azinzile. IHydrogen sulfide iyikhemikhali evuthayo futhi eyingozi. Uma ixutshwe nomoya, ingakha ingxube eqhumayo. Kungabangela ukuvutha nokuqhuma lapho kuvezwe amalangabi avulekile nokushisa okuphezulu. Kuphinde kube yinto eyingozi futhi enobuthi kakhulu. I-hydrogen sulfide ene-concentration ephansi inemiphumela emehlweni, ohlelweni lokuphefumula kanye nesistimu yezinzwa emaphakathi. Ukuhogela inani elincane le-hydrogen sulfide egxilile kakhulu kungabulala ngesikhathi esifushane. Isetshenziswa ekwenzeni ama-phosphors okwenziwa, i-electroluminescence, ama-photoconductors, amamitha okuchayeka ezithombeni, njll. I-ejenti yokunciphisa i-Organic synthesis. Isetshenziselwa ukucwenga insimbi, izibulala-zinambuzane, imithi, ukuvuselelwa kabusha kwe-catalyst. Ama-reagents ajwayelekile. Ukulungiswa kwama-sulfide ahlukahlukene. Isetshenziswa ekwenzeni ama-sulfide angaphili, futhi isetshenziswa nasekuhlaziyeni amakhemikhali njengokuhlonza i-ion yensimbi. I-high-purity hydrogen sulfide isetshenziswa ku-semiconductor nakweminye imikhakha. Ingasetshenziswa futhi embonini yamakhemikhali okuvikela kazwelonke, izimaphakathi zemithi nezibulala-zinambuzane, ukucwengisiswa kwensimbi okungeyona ayoni kanye nokwelashwa kokulungiswa kwendawo yensimbi, esetshenziswa ekulungiseni igesi evamile, igesi yokulinganisa, nokuhlaziya amakhemikhali njengokuhlonza ama-ion ensimbi. Impahla ebalulekile yokwenziwa kwezinto ezibonakalayo ze-infrared optical. Imithetho yesitoreji: Gcina endaweni epholile, nengena umoya. Gcina kude nomlilo nemithombo yokushisa. Izinga lokushisa lokugcina akufanele lidlule ku-30°C. Gcina isitsha sivalwe ngokuqinile. Kufanele igcinwe ngokuhlukana nama-oxidants nama-alkali, futhi igweme ukugcinwa okuxubile. Sebenzisa izibani ezingaqhumi kanye nezindawo zokungenisa umoya. Akuvunyelwe ukusebenzisa imishini namathuluzi ajwayele ukuvela izinhlansi. Indawo yokugcina kufanele ifakwe okokusebenza okuphuthumayo okuvuzayo.

Isicelo:

①Ukukhiqizwa kwezinhlanganisela ze-thioorganic:

Amakhemikhali amaningana e-organosulfur akhiqizwa kusetshenziswa i-hydrogen sulfide. Lezi zihlanganisa i-methanethiol, i-ethanethiol, ne-thioglycolic acid.

②Ikhemikhali yokuhlaziya:

Iminyaka engaphezu kwekhulu, i-hydrogen sulfide yayibalulekile kukhemistri yokuhlaziya, ekuhlaziyeni kwekhwalithi ye-inorganic ion yensimbi.

③Isandulela sama-sulfide ensimbi:

Njengoba kukhonjisiwe ngenhla, ama-ion ensimbi amaningi asabela nge-hydrogen sulfide ukuze anikeze ama-sulfide ensimbi ahambisanayo.

④Izinhlelo zokusebenza ezihlukene:

IHydrogen sulfide isetshenziselwa ukuhlukanisa i-deuterium oxide, noma amanzi asindayo, emanzini avamile ngenqubo ye-Girdler sulfide.

Iphakheji evamile:

Inzuzo:

①Ukuhlanzeka okuphezulu, indawo yakamuva;

②ISO umenzi wesitifiketi;

③Ukulethwa okusheshayo;

④Izinto ezingavuthiwe ezizinzile ezivela ekunikezeni kwangaphakathi;

⑤Isistimu yokuhlaziya eku-inthanethi yokulawula ikhwalithi kuso sonke isinyathelo;

⑥Isidingo esiphezulu kanye nenqubo yokucophelela yokuphatha isilinda ngaphambi kokugcwalisa;
