Umusaruro wa Sodium Hydrosulfide binyuze mu kwinjiza NaOH
Uburyo busanzwe bwo kwinjiza NaOH
Iyo igipimo cya NaHS sodium hydrosulfide kigeze 70%, ikora uduce duto tw’amazi.
Iyo ikoze mu rugero ruto, iba mu bwoko bwa trihydrate y'amazi.
Uburyo bikorwa:
Icupa rizunguruka rifite ijosi ritatu rya litiro 1 rifite agakoresho ko gukangura no gukangura umwuka (rifatanye n'umuyoboro wo kumisha wa CaCl₂).
Agacupa gasukurwa na azote yumye, hanyuma gashyirwamo Ethanol idafite amazi ya mL 200 (3.4 mol).
Garama 12 (0.522 mol) z'icyuma gisukuye cya sodiyumu zongerwamo uduce duto duto mu gihe cyo kuvanga no kongera kuzura kugeza bishongeshejwe neza.
Umuyoboro w’umwuka winjizwa mu mazi ushyirwamo, hanyuma H₂S yumye (yumishijwe hejuru ya P₂O₅) igashyirwamo utubumbe ku dupira 5–10 ku masegonda mu gihe cy’amasaha 2 mu gihe cyo kuvanga.
Nyuma yo gukonjesha, hongerwamo 750 mL ya ether anhydrous kugira ngo NaHS sodium hydrosulfide ihinduke burundu.
Imyitozo:
Uruvange ruvugururwa vuba (coarse frit) kugira ngo hirindwe ko ubushuhe bwinjira.
Igikomeye cyogezwaho 3× na ether ya anhydrous, hanyuma kikamishwa mu cyuma gikuraho ubushyuhe (CaCl₂) mu gihe cy'amasaha menshi.
Umusaruro: 29.4 g ya ≥98% ya NaHS yuzuye.
