Okukola Sodium Hydrosulfide nga tuyita mu Sodium Ethoxide & H2S
Okuteekateeka nga oyita mu Sodium Ethoxide ne Dry Hydrogen Sulfide
Enteekateeka y’Ebyuma:
Eccupa ya 150 mL ng’erina emmundu ey’oku mabbali ejjuza... 20 mL za freshly distilled Ethanol atalina mazzi ne 2 g z’ebitundu by’ebyuma ebiyonjo ebya sodium (ebitaliimu layers za oxide) ..
Flask eno eteekebwamu reflux condenser ne drying tube, era sidearm esibibwa okumala akaseera.
Oluvannyuma lwa sodium ethoxide okutandika okutondebwa, eky’okwongerako 4. 4.0 mL ya ethanol atalina mazzi eyongerwako mu bitundutundu okutuusa lw’esaanuuka ddala.
Enkolagana ne Dry H2S:
Tubu y’endabirwamu eyingizibwa okuyita mu sidearm mu solution, era omukka gwa H2S omukalu gufuumuuka okuyita mu (kakasa embeera eziyingira mu mpewo okuziyiza empewo okuyingira).
Ekisengejjero kijjula H2S, oluvannyuma ne kisengejebwa okuggyamu ebitonnye byonna.
Ekisengejjeddwa kikyusibwa ne kiteekebwa mu fulasika enkalu eya kkooni, era 50 mL za ether entuufu eyongerwako, amangu ago n’etonnyesa NaHS enjeru.
Ether endala (~110 mL total) eyongerwako mu bitundu okutuusa nga tewali nkuba ndala ebaawo.
Ekitonnyeze kisengejebwa mangu, kinaazibwa emirundi 2–3 ne ether entuufu, ne kikalira wansi w’obuziba.
Ekintu kino kiba kya bulongoofu mu kwekenneenya. Ku bulongoofu obw’amaanyi, recrystallization okuva mu ethanol/ether esobola okukolebwa.
