Yub me Sodium Hydrosulfide ki Sodium Ethoxide & H2S
Yub kun kitiyo ki Sodium Ethoxide ki Dry Hydrogen Sulfide
Yub me jami tic:
Gin ma ki lwongo ni 150 mL flask ki laterrm ki keto iye 20 mL me gin ma ki kwanyo nyen Ethanol ma pe ki pii ki 2 g me jami ma ki lwongo ni sodium metal pieces (labongo oxide layers).
Flask ni ki keto iye reflux condenser ki drying tube, ki laterrm ni ki umu pi kare manok.
I ngeye ma sodium ethoxide ocako dongo, medo 40 mL me ethanol ma pe ki pii ki medo i dul mogo nio ka dong otum woko.
Kit ma Dry H2S:
Ki keto gin ma ki lwongo ni glass tube ki i cing cing ma ki keto i pii ni, ki yamo ma otwo ma ki lwongo ni H2S ki keto iye (nen ni yamo pe donyo iye me gengo yamo donyo iye).
Gin ma ki rubu ni ki pongo ki H2S, ki dong ki yubu me kwanyo gin mo kiken ma odonyo iye.
Gin ma ki lwongo ni filtrate ni ki keto i dry conical flask, ki 50 mL me gin ma ki lwongo ni absolute ether ki medo, cut cut okelo NaHS ma ler.
Ki medo ether (~110 mL weny) i dul mogo nio ka pe ki medo pii mo kiken.
Gin ma odonyo ni ki kwanyo oyot, ki lwoko tyen 2-3 ki ether ma pe ki keto iye gin mo, ki ki juku ne i te vacuum.
Gin ma ki yubu ni tye maleng. Pi bedo maleng, dwoko piny ki i ethanol/ether ki twero tiimo ne.
