Ukukhiqizwa kwe-Sodium Hydrosulfide nge-Sodium Ethoxide kanye ne-H2S
Ukulungiselela nge-Sodium Ethoxide kanye ne-Dry Hydrogen Sulfide
Ukusethwa Kwemishini:
Ibhodlela elingu-150 mL elinengalo eseceleni lishajwe nge 20 mL we-distilled esanda kuhluzwa I-Ethanol Engenamanzi futhi 2 g wezingcezu zensimbi ye-sodium ehlanzekile (engenazo izendlalelo ze-oxide).
Iflaski ifakwe i-reflux condenser kanye nepayipi lokomisa, kanti ingalo eseceleni ivalwe okwesikhashana.
Ngemva kokuba i-sodium ethoxide iqala ukwakheka, i-sodium ethoxide eyengeziwe 40 mL ye-ethanol engenamanzi yengezwa ngezingxenye kuze kube yilapho incibilika ngokuphelele.
Ukusabela nge-Dry H₂S:
Ishubhu yengilazi ifakwa ngengalo eseceleni esixazululweni, bese kuthi igesi eyomile ye-H₂S igeleze (qinisekisa ukuthi umoya awungeni kahle ukuze kuvinjelwe ukungena komoya).
Isixazululo sigcwele i-H₂S, bese sihlungwa ukuze kususwe noma yikuphi ukugayeka.
I-filtrate idluliselwa ebhodleleni elomile eliyindilinga, bese 50 mL ye-absolute ether kuyengezwa, okwenza i-NaHS emhlophe ivele ngokushesha.
I-ether eyengeziwe (ephelele engu-110 mL) ingezwa ngezingxenye kuze kube yilapho kungekho mvula eyengeziwe.
I-precipitate ihlungwa ngokushesha, igezwe izikhathi ezingu-2-3 nge-absolute ether, bese yomiswa ngaphansi kwe-vacuum.
Umkhiqizo uhlanzekile ngokuhlaziya. Ukuze kube msulwa kakhulu, kungenziwa ukuphinda kusetshenziswe i-ethanol/ether.
