Sodium Hydrosulfide Production nikadhu kud i Sodium Ethoxide & H2S
Yub ku Sodium Ethoxide man Dry Hydrogen Sulfide
Kethu jam tic:
A 150 mL flask ku cing cing juketho ku 20 mL pa ma nyen Anhydrous Ethanol man 2 g pa sodium maleng (ma epe ku oxide layers).
Flask ne juyike ku reflux condenser man drying tube, man thenge mi cinge juyike pi kare manok.
I ngei ma sodium ethoxide ucaku wok, piny mukende 40 mL pa anhydrous ethanol jumedo i dul moko nitundu ethum.
Adwogi ku Dry H2S:
Jubolo tube mi gilasi kud i cing cing i pii, man H2S gas ma muthwo jubolo kud i iye (nen nia yamo kud umond i iye).
Jam pii ne upong ku H2S, man juyike pi kwanyu piny moku ci ma ucungo.
Filtrate ne jucwalo i flask ma muthwo, man 50 mL pa ether ma rwinyo jumedo, ndhundhu ma nyayu NaHS matar.
Ether mukende (~110 mL zo) jumedo i dul moko nitundu pii moko ope.
Piny ma wok kud i iye juyike pio pio, juyike wang 2-3 ku absolute ether, man juyike i vacuum.
Piny ma jucul utiye maleng. Pi leng pa piny, jucopo timo recrystallization kud i ethanol/ether.
