Okukora Sodium Hydrosulfide kurabira omu kunywa NaOH
Omuringo gw'okunywa NaOH ogwa butoosha
Obu NaHS sodium hydrosulfide erikuba neehika aha . 70%, nikikora ebicweka by’amaizi ebirimu amaizi.
Omu nkora y’ahansi, neebaho nk’amaizi g’amaizi mashatu.
Kuratira:
Ekikopo kya 1 L ekiine ebitsya bishatu ebirikwetoorora ahansi kiine ekikwato ky‘okusheeshasheesha n‘okugaruzaho (ekiine akakwate n‘ekikopo ky‘okwozya CaCl2).
Ekikopo ekyo nikishemezibwa nitrogen eyomire, reero kishukwamu . 200 mL (3.4 mol) etanoli etaine maizi.
12 g (0.522 mol) y’ekyoma kya sodium ekishemeire nikiteebwa omu bicweka bikye ahansi y’okugiteera n’okugigaruza enyima kuhitsya obu eraashekyerere kimwe.
Ekikopo ky‘okutaho gaasi nikiteebwa omu maizi, kandi H2S eyomire (eyomire aha P2O5) neefumbirwa aha bicupuri 5–10/sec kumara 2 h ahansi y‘okugifubira.
Bwanyima y‘okukyendeeza, 750 mL ya ether etaine maizi neeyongyerwamu kubaasa kusheeshasheesha NaHS sodium hydrosulfide yoona.
Okukora:
Omutaano nigurahuka kusendwa (coarse frit) okuzibira okunywa obutagatsi.
Ekigumire nikyozibwa 3× na ether etarimu maizi, reero kyomyezibwa omu nkora y’okukyendeeza amaizi (CaCl2) kumara eshaaha nyingi.
Ebirikurugamu: 29.4 g ya ≥98% ya NaHS eshemeire.
