Hydrogen Sulfide (H2S)

Magadzirirwo ehunyanzvi

Hydrogen sulfide chinhu chisina kugadzirwa chine fomura yeH2S uye huremu hwemamorekuru hwe34.076. Pasi pemamiriro ezvinhu akajairwa, igesi inobvira neacid. Haina ruvara uye ine hwema hwemazai akaora pahuwandu hwakaderera. Mushonga wemvura ihydrogen sulfuric acid, iyo isina simba pane carbonic acid, asi yakasimba kupfuura boric acid. Hydrogen sulfide inonyungudika mumvura, inonyungudika nyore nyore mualcohols, petroleum solvents nemafuta asina kuchena, uye hunhu hwayo hwemakemikari hahuna kugadzikana. Hydrogen sulfide ikemikari inobvira nemoto uye ine njodzi. Kana ikasanganiswa nemhepo, inogona kugadzira musanganiswa unoputika. Inogona kukonzera kupisa nekuputika kana yaiswa pamoto wakavhurika uye kupisa kwakanyanya. Ichinhu chinopisa uye chine chepfu yakawanda. Hydrogen sulfide ine huwandu hushoma hwehydrogen sulfide ine mhedzisiro pamaziso, system yekufema uye central nervous system. Kufema huwandu hushoma hwehydrogen sulfide ine huwandu hwakawanda hwemvura kunogona kuuraya munguva pfupi. Inoshandiswa mukugadzira phosphors dzekugadzira, electroluminescence, photoconductors, photoelectric exposure metres, nezvimwewo. Organic synthesis reducing agent. Inoshandiswa pakuchenesa simbi, mishonga yezvipembenene, mushonga, catalyst regeneration. General reagents. Kugadzirira sulfides dzakasiyana-siyana. Inoshandiswa mukugadzira inorganic sulfides, uye inoshandiswawo mukuongorora makemikari akadai sekuziva ma ions esimbi. Hydrogen sulfide yakachena kwazvo inoshandiswa mu semiconductor nedzimwe nzvimbo. Inogona zvakare kushandiswa muindasitiri yemakemikari ekudzivirira nyika, mishonga yemishonga nemishonga yezvipembenene, kuchenesa simbi isina ferrous uye kugadzirisa simbi pamusoro pekugadzirisa, inoshandiswa mukugadzirira gasi rakajairika, gasi rekuenzanisa, uye kuongorora makemikari akadai sekuziva ma ions esimbi. Chinhu chakakosha pakugadzira zvinhu zve infrared optical. Nzira dzekuchengetedza: Chengeta mudura rinotonhorera, rine mhepo inofefetera. Chengeta kure nemoto nemhepo. Tembiricha yekuchengetera haifanirwe kudarika 30°C. Chengeta mudziyo wakavharwa zvakanaka. Unofanira kuchengetwa wakaparadzana ne oxidants ne alkalis, uye dzivisa kuchengetwa kwakasiyana. Shandisa mwenje unodzivirira kuputika uye nzvimbo dzekufema. Hazvibvumirwi kushandisa michina nezvishandiso zvinogona kupfuta sparks. Nzvimbo yekuchengetera zvinhu inofanira kunge ine michina yekurapa nekukasika inodonha mvura.

Kushandiswa:

①Kugadzirwa kwemakemikari e thioorganic:

Makemikoro akati wandei e organosulfur anogadzirwa achishandisa hydrogen sulfide. Izvi zvinosanganisira methanethiol, ethanethiol, uye thioglycolic acid.

②Kemistri yekuongorora:

Kwenguva inopfuura zana remakore, hydrogen sulfide yaive yakakosha mukuongorora kemesitiri, mukuongorora kwemhando yezvinhu zvisina kugadzirwa zvesimbi.

③Chinotangira sulfide yesimbi:

Sezvakaratidzwa pamusoro apa, maion esimbi akawanda anoita zvinoenderana nehydrogen sulfide kuti ape sulfide yesimbi inoenderana.

④Mashandisirwo akasiyana-siyana:

Hydrogen sulfide inoshandiswa kuparadzanisa deuterium oxide, kana kuti mvura inorema, kubva mumvura yakajairika kuburikidza neGirdler sulfide process.

Pakeji yakajairika:

Zvakanakira:

①Kuchena kwakanyanya, nzvimbo itsva;

②Mugadziri wezvitupa zveISO;

③Kutumira nekukurumidza;

④Zvinhu zvakagadzika kubva mukati;

⑤Sisitimu yekuongorora yepamhepo yekudzora mhando padanho rega rega;

⑥Kushandiswa kwakawanda uye kwakanyatsorongwa kwekubata silinda usati wazadza;
