Sodium Hydrosulfide wɔwɔ to Sodium Ethoxide & H2S dzi
Dzadzraɖo to Sodium Ethoxide kple Dry Hydrogen Sulfide dzi
Mɔ̃wo ƒe Ðoɖowɔwɔ:
Wotsɔa 150 mL ƒe flask si me axadzitu le la dea agba me 20 mL si woɖe tso tsi yeye me Ethanol si me tsi mele o kple 2 g ƒe sodium ga kakɛ dzadzɛwo (siwo me oxide ƒe ƒuƒoƒo mele o) ..
Wotsɔa nusi wotsɔna tsia tsia me kple nusi wotsɔna ƒua tsii dea nugoe la me, eye wotua axadzinu la hena ɣeyiɣi aɖe.
Ne sodium ethoxide dze ƒoƒo gɔme vɔ la, ga bubu aɖe kpena ɖe eŋu 4. 4.0 mL ƒe ethanol si me tsi mele o wotsɔa wo dea eme le akpa vovovowo me vaseɖe esime wòƒu keŋkeŋ.
Nuwɔna kple Dry H2S:
Wotsɔa ahuhɔ̃e me mɔ̃ aɖe to axadzinu la me dea tsi si woɖe tso eme la me, eye wotsɔa H2S gas ƒuƒu toa eme (kpɔ egbɔ be ya megena ɖe eme o be ya nagage ɖe eme o).
Wotsɔa H2S yɔa tsi si woɖe tso eme la me, emegbe woɖea tsi si le tsia me la ɖa.
Wotsɔa tsi si woɖe tso eme la dea tsigoe ƒuƒu si le abe kɔnu ene me, eye 50 mL ƒe ether blibo wotsɔa kpe ɖe eŋu, si wɔnɛ be NaHS ɣiwo ƒuna enumake.
Wotsɔa ether bubu (~110 mL katã) dea eme le akpa vovovowo me vaseɖe esime tsidzadza bubu aɖeke nagadzɔ o.
Woɖea tsi si ƒo la kabakaba, woklɔa eŋu zi 2–3 kple ether blibo, eye wotsɔa ya ƒua gbe le ya si me ya mele o me.
Nusi wowɔ la ƒe dzadzɛnyenye le numekuku me. Be dzadzɛnyenye si lolo wu la, woate ŋu awɔ recrystallization tso ethanol/ether me.
