Vuhumelerisi bya Sodium Hydrosulfide hi ku tirhisa Sodium Ethoxide & H2S
Ku lulamisiwa hiku tirhisa Sodium Ethoxide na Dry Hydrogen Sulfide
Ku Hlela Switirhisiwa: .
Flask ya 150 mL leyingana sidearm yi chajiwa hi 20 mL ya distilled leyintshwa Ethanol leyi nga riki na mati na 2 g ya swiphemu swa nsimbi swa sodium leswi tengeke (leswi nga riki na swiphemu swa oxide) ..
Flask leyi yi vekiwile na reflux condenser na drying tube, naswona sidearm yi pfaleriwile swa xinkarhana.
Endzhaku ka loko sodium ethoxide yi sungule ku vumbiwa, ku engeteriwa 4. 4.0 mL ya ethanol leyi nga riki na mati yi cheriwa hi swiphemu kufikela yi n’oka hiku hetiseka.
Ku angula na Dry H2S:
Chubu ra nghilazi ri nghenisiwa hi sidearm eka solution, naswona gasi yo oma ya H2S yi bubbled through (tiyisisa swiyimo leswinga ngheniwiki hi moya kuva ku sivela ku nghena ka moya).
Nkatsakanyo wu tatiwa hi H2S, kutani wu sefiwa ku susa swilo leswinga khuluka.
Filtrate yi hundziseriwa eka flask yo oma ya conical, naswona 50 mL ya ether leyi heleleke yi engeteriwa, hi ku hatlisa yi khuluka NaHS yo basa.
Ether yo engetelela (~110 mL hinkwayo) yi cheriwa hi swiphemu kufikela loko kungari na mpfula yin’wana leyi humelelaka.
Precipitate yi hatla yi sefiwa, yi hlantswiwa minkarhi ya 2–3 hi absolute ether, naswona yi omisiwa ehansi ka vacuum.
Xiendliwa lexi i xa vutengi bya vuxopaxopi. Kuva ku basa swinene, recrystallization kusuka eka ethanol/ether yinga endliwa.
