Uguhingura Sodium Hydrosulfide biciye mu Kunywa NaOH
Uburyo busanzwe bwo gufata NaOH
Igihe NaHS igera kuri 70%, rigira ibipande vy’amazi.
Iyo iri mu bipimo bito, ibaho nk’amazi y’amazi atatu.
Ubugyo:
Igikoresho co gutera 1 L gifise amazosi atatu, gifise hasi ikikuje, gifise igikoresho co gutera umuriro n’igikoresho co gutera umuriro (gifatanye n’uruzitiro rwo kwumisha CaCl2).
Ico gitereko kirasukurwa n’azote yumye, hanyuma kigashirwamwo . 200 mL (3.4 mol) ya etanoli idafise amazi.
12 g (0.522 mol) y’icuma ca sodium gisukuye yongerwa mu bipande bitobito mu gutera ivyatsi no gusubiramwo gushika bipfutse bimwe bishitse.
Mu mazi hashirwamwo umuyoboro w’inzira y’umuyagankuba, hanyuma H2S yumutse (yumutse hejuru ya P2O5) igatera ibibumbano ku bibumbano 5–10/sec mu kiringo c’amasaha 2 ivugururwa.
Inyuma yo gukonja, 750 mL y’etere idafise amazi yongerwako kugira ngo NaHS sodium hydrosulfide ivyure burundu.
Gukora:
Ivyo bivanze biracungururwa ningoga (coarse frit) kugira ngo ntibishiremwo ubukonje.
Ico kintu gikomeye gisukurwa 3× n’amazi atagira amazi, hanyuma kikama mu gikoresho co kwuma (CaCl2) amasaha menshi.
Umusaruro: 29,4 g ya ≥98% ya NaHS isukuye.
