I-CAS No. 7783-7-5 I-Hydrogen Selenide Factory. Bayini abahlinzeki beHydrogen Selenide
I-Hydrogen selenide, eyaziwa nangokuthi i-hydroselenic acid ngesimo sayo se-aqueous, inefomula yamakhemikhali ethi H₂Se. Inombolo yayo ye-CAS impela 7783-7-5. Lesi sithako siyigesi engenambala enobuthi kakhulu futhi obusa umlilo. Nazi ezinye izici ze-hydrogen selenide:
Izakhiwo Zomzimba:
Ukubukeka: Igesi engenambala enephunga elimnandi elifana namaqanda abolile, nakuba lishube kakhulu.
Indawo yokubilisa: -41.4 °C.
Ukuncibilika: -85.4 °C.
Ukuminyana: Kwa-STP, kuminyene kunomoya.
I-Solubility: Incibilika emanzini nasezincibilikisini zemvelo ezitholakala ezindaweni ezishisayo.
Izakhiwo Zekhemikhali:
Ukusebenza kabusha: Isebenza kakhulu futhi ingavutha ngokuzenzekelayo emoyeni.
I-Acidity: Emanzini, yenza i-asidi ebuthakathaka, i-hydroselenic acid (H₂Se).
Ukubola: Ingabola ibe i-elenium elemental ne-hydrogen ngaphansi kwezimo ezithile.
Isebenzisa:
Imboni ye-Semiconductor: Isetshenziswa ekukhiqizeni ama-selenium compounds kuma-semiconductors namadivayisi we-photovoltaic.
I-Analytical Chemistry: Isetshenziswa njenge-reagent kukhemistri yokuhlaziya.
Ucwaningo: Isetshenziswa ocwaningweni lwesayensi ukuze kuhlanganiswe izinhlanganisela eziqukethe i-selenium.
Ukucatshangelwa kokuphepha:
Ubuthi: Ubuthi obudlulele ngokuhogela, ngisho nasezindaweni eziphansi; ukuchayeka kungaholela emiphumeleni emibi yezempilo kuhlanganise nokufa.
Ukuvutha: Igesi evuthayo engenza izingxube eziqhumayo ngomoya.
Ukuphatha: Kudinga izimiso zokuphepha eziqinile, okuhlanganisa ukusetshenziswa kwezivalo zomusi kanye nezinto ezifanele zokuzivikela.
Ngenxa yobuthi bayo nezidingo zokuphatha, i-hydrogen selenide ngokuvamile ayitholakali kubahlinzeki bamakhemikhali abavamile. Esikhundleni salokho, imvamisa ikhiqizwa esizeni kuma-laboratories noma ezindaweni lapho isetshenziswa khona ngokushesha. Abahlinzeki abakhethekile ababhekelela izimboni ezidinga i-hydrogen selenide bangaba umthombo wokuthenga le nto, nakuba kuvame kakhulu ukuthi yenziwe njengoba kudingeka kunokuba igcinwe noma ithuthwe.
Izinkampani ezihlinzeka nge-hydrogen selenide noma izandulela zayo zingase zihlanganise abakhiqizi bamakhemikhali abakhethekile noma labo ababhekelela ngokukhethekile imboni ye-semiconductor. Njalo qinisekisa ukuthobela imithetho yendawo kanye neziqondiso zokuphepha lapho usebenza ne-hydrogen selenide, futhi uyiphathe ngaphansi kwezimo ezilawulwayo kuphela ngezinyathelo zokuphepha ezifanele.
I-Shanghai Wechem Chemical Co., Ltd. yakhiwe iqembu lochwepheshe abanolwazi nabanekhono abanolwazi oluningi namakhono ochwepheshe emkhakheni wamagesi akhethekile nama-isotopes azinzile. Ngokuqhubeka nokusungula izinto ezintsha kanye nemizamo yocwaningo nentuthuko, siqhubeka sethula imikhiqizo yekhwalithi ephezulu nehlanzekile ukuze sihlangabezane nezidingo eziguqukayo zamakhasimende ethu. Uma udinga lo mkhiqizo, sicela ukhululeke ukuxhumana nathi nganoma yisiphi isikhathi!
