Kukhicitwa kweSodium Hydrosulfide nge Sodium Ethoxide & H2S
Kulungiselela ngekusebentisa iSodium Ethoxide kanye neHayidrojeni Sulfide Leyomile
Kusetha I-Apharathasi:
Iflaski le-150 mL lenesikhali lesiseceleni ishaja nge 20 mL we lokusanda kuhlungwa I-Ethanol lengenamanti futsi 2 g wetincetu tensimbi letihlantekile te-sodium (letingenato tincenye te-oxide).
Le flask ifakwe i reflux condenser kanye nelishubhu lekomisa, bese le sidearm ivalwa kwesikhashana.
Ngemuva kwekutsi i-sodium ethoxide icale kwakheka, i- 40 mL we-ethanol lete emanti kufakwa ngetincenye kuze kube ngulapho sekuncibilike ngalokuphelele.
Kuphendvula nge H2S leyomile:
Lishubhu lengilazi lifakwa nge sidearm kulesisombululo, bese igesi leyomile ye H2S iyabubblelwa ngayo (cinisekisa timo letingangeni moya kwentela kuvikela kungena kwemoya).
Lesixazululo sigcwele iH2S, bese siyahlungwa kwentela kususa noma ngutiphi tintfo letifakwe eceleni.
Le filtrate idluliselwa ku flask leyomile ye conical, futsi 50 mL we-ether lephelele kungetiwe, ngekushesha kuvele kuvele iNaHS lemhlophe.
I-ether lengetiwe (~110 mL lilonkhe) ifakwa ngetincenye kuze kube ngulapho kungabikhona lenye imvula leyentekako.
Le precipitate ihlungwa ngekushesha, igezwe tikhatsi letingu 2-3 nge ether lephelele, bese yomiswa ngaphansi kwe vacuum.
Lomkhicito ungumsulwa wekuhlatiya. Kute kube nekuhlanteka lokusetulu, kuphindze kwentiwe kabusha kusuka ku ethanol/ether kungentiwa.
