Kupanga Sodium Hydrosulfide kudzera mu Sodium Ethoxide ndi H2S
Kukonzekera kudzera mu Sodium Ethoxide ndi Dry Hydrogen Sulfide
Kukhazikitsa Chida:
Botolo la 150 mL lokhala ndi mkono wozungulira lili ndi chogwirira 20 mL ya distilled yatsopano Ethanol Wopanda Madzi ndi 2 g ya zidutswa zoyera za sodium metal (zopanda zigawo za oxide).
Botololo lili ndi choziziritsira mpweya (reflux condenser) ndi chubu chowumitsira, ndipo mkono wa m'mbali umatsekedwa kwakanthawi.
Pambuyo poti sodium ethoxide yayamba kupangidwa, chowonjezera 40 mL ya ethanol yopanda madzi imawonjezedwa m'magawo mpaka itasungunuka kwathunthu.
Kuyankha ndi Dry H₂S:
Chubu chagalasi chimayikidwa kudzera m'khwapa la mbali mu yankho, ndipo mpweya wouma wa H₂S umatuluka (onetsetsani kuti mpweya sulowa bwino kuti mpweya usalowe).
Yankho lake limadzazidwa ndi H₂S, kenako limasefedwa kuti lichotse madontho aliwonse.
Filtrate imasamutsidwira ku botolo louma lozungulira, ndipo 50 mL ya absolute ether imawonjezedwa, nthawi yomweyo NaHS yoyera imagwa.
Ether yowonjezera (yomwe ili pafupifupi 110 mL yonse) imawonjezedwa m'magawo mpaka mvula isanagwe.
Mpweya wothira umasefedwa mwachangu, kutsukidwa kawiri mpaka katatu ndi ether yokwanira, ndikuumitsidwa pansi pa vacuum.
Chogulitsachi ndi chaukhondo wowunika. Kuti chikhale choyera kwambiri, kubwezeretsanso kwa ethanol/ether kumatha kuchitika.
