Ukukhiqizwa kwe-Sodium Hydrosulfide nge-Sodium Ethoxide & H2S
Ukulungiselela nge-Sodium Ethoxide kanye ne-Dry Hydrogen Sulfide
Ukuhlela i-apharathasi:
Iflaski eyi-150 mL ene-siderm ifakwe 20 mL ye-distilled esanda kufakwa I-Ethanol engenamanzi kunye 2 g yeengcezu zensimbi ezihlanzekileko zesodiyamu (ezingenawo amalayini we-oxide).
Iflaski ifakwe i-reflux condenser kanye neshubhu yokomisa, begodu i-siderm ivaliwe okwesikhatjhana.
Ngemva kobana i-sodium ethoxide ithome ukwakheka, enye 40 mL ye-ethanol engenamanzi ifakwa ngeengcenye bekube kulapho incibilika ngokupheleleko.
Ukusabela nge-H2S eyomileko:
Itjhubhu yengilazi ifakwa nge-siderm ngaphakathi kwesixazululo, bese igesi eyomileko ye-H2S ivuvuka ngaphakathi (qinisekisa ubujamo obungenamoya ukukhandela ukungena komoya).
Isixazululo sigcwele i-H2S, bese siyahlungwa ukususa nanyana ngiziphi iinqhema.
Isefo idluliselwa eflaskini eyomileko, begodu 50 mL ye-ether epheleleko ifakwa, msinyana yenza i-NaHS emhlophe.
I-ether eyengeziweko (~110 mL yoke) ifakwa ngeengcenye bekube kulapho kungekho enye imvula.
I-precipitate iyahlungwa msinyana, ihlanzwe ka-2-3 nge-ether epheleleko, bese yomiswe ngaphasi kwe-vacuum.
Umkhiqizo lo ubumsulwa bokuhlaziya. Ukuze kube nokuhlanzeka okuphezulu, ukuvuselelwa kwe-ethanol/ether kungenziwa.
