Kugadzirwa kweSodium Hydrosulfide kuburikidza neSodium Ethoxide neH2S
Kugadzirira kuburikidza neSodium Ethoxide neDry Hydrogen Sulfide
Kugadzika kweMudziyo:
Chirongo che 150 mL chine ruoko rweparutivi chakaiswa 20 mL yemvura itsva yakasanganiswa Ethanol isina mvura uye 2 g yezvidimbu zvesimbi yakachena yesodium (isina oxide layers).
Chirongo chacho chine reflux condenser nechubhu yekuomesa, uye ruoko rweparutivi rwakavharwa kwenguva pfupi.
Mushure mekunge sodium ethoxide yatanga kuumbwa, imwezve 40 mL ye ethanol isina mvura inowedzerwa muzvikamu kusvika yanyungudika zvachose.
Kuita neDry H₂S:
Chubhu yegirazi inopinzwa neparutivi peruoko mumhinduro, uye gasi reH₂S rakaoma rinobuda (ita shuwa kuti mhepo haipindi zvakanaka kudzivirira kupinda kwemhepo).
Mushonga wacho unozadzwa neH₂S, wozoseferwa kuti ubvise chero mvura inonaya.
Filtrate inoendeswa kuflask yakaoma ine conical, uye 50 mL ye absolute ether inowedzerwa, zvichiita kuti NaHS chena ibve pakarepo.
Imwe ether (~110 mL yese) inowedzerwa muzvikamu kusvika mvura yapera.
Precipitate inosefetwa nekukurumidza, yogezwa kaviri kusvika katatu ne absolute ether, yoomeswa pasi pevacuum.
Chigadzirwa chacho chakachena zvakanyanya. Kuti chive chakachena zvakanyanya, zvinogona kuitwa kuti pave nekugadziriswazve kwecrystallization kubva ku ethanol/ether.
