Sodium Ethoxide & H2S hmanga Sodium Hydrosulfide siam chhuah a ni
Sodium Ethoxide leh Dry Hydrogen Sulfide hmanga buatsaih
Apparatus siam dan tur: 1.1.
150 mL flask sidearm nei chu charge a ni 20 mL distilled thar a ni Tui awm lo Ethanol a ni leh Sodium metal piece thianghlim (oxide layer awm lo) 2 g ..
Flask-ah hian reflux condenser leh drying tube dah a ni a, sidearm chu hun eng emaw chen sealed a ni.
Sodium ethoxide a lo awm tan hnuah, additional 4. 4. A rilru a hah lutuk chuan a rilru a buai em em a0 mL tui awm lo ethanol a ni chu a hmin vek thlengin a then a dah a ni.
Dry H2S nena inrem dan:
Sidearm kaltlangin glass tube chu solution chhungah dahin, dry H2S gas chu bubbled through a ni (airtight condition-ah airtight condition enfiah la, boruak lut lo turin).
Solution chu H2S hmangin saturate a ni a, chutah chuan precipitate awm zawng zawng paih chhuah nan filter a ni.
Filtrate chu dry conical flask-ah dah a ni a, 50 mL a ni a, absolute ether a awm bawk a dah belh a, NaHS dum a rawn precipit nghal a ni.
Ether dang (~110 mL total) chu a then a then a, ruahtui tlak leh loh thlengin dah belh a ni.
Precipitate chu rang takin an filter a, absolute ether hmangin vawi 2–3 an silfai a, vacuum hnuaiah an vawt bawk.
A product hi analytical purity a ni. Thianghlimna sang zawk atan chuan ethanol/ether atanga recrystallization tih theih a ni.
