Samar da Sodium Hydrosulfide ta hanyar Sha NaOH
Hanyar Sha NaOH ta Al'ada
Lokacin da yawan sinadarin sodium hydrosulfide na NaHS ya kai kashi 70%, yana samar da flakes na dihydrate.
A ƙananan yawan da ake samu, yana wanzuwa a matsayin ruwa mai trihydrate.
Tsarin aiki:
An saka wani kwalba mai zagaye mai wuya uku mai lita 1 da na'urar motsa jiki da kuma na'urar sanyaya iska (wanda aka haɗa da bututun busarwa na CaCl₂).
Ana tsaftace kwalbar da busasshiyar nitrogen, sannan a cika ta da 200 ml (3.4 mol) ethanol mai ruwa.
Ana ƙara gram 12 (0.522 mol) na ƙarfe mai tsabta na sodium a ƙananan gutsuttsura a hankali ana juyawa har sai ya narke gaba ɗaya.
Ana saka bututun iskar gas a cikin ruwan, kuma ana zuba busasshen H₂S (wanda aka busar akan P₂O₅) a kumfa 5-10 a cikin daƙiƙa na tsawon awanni 2 a lokacin da ake juyawa.
Bayan sanyaya, ana ƙara 750 mL na ether mai narkewa don ya zube NaHS sodium hydrosulfide gaba ɗaya.
Aiki:
Ana tace hadin da sauri (wanda aka yi da ɗanɗano) don hana shanye danshi.
Ana wanke dattin da ether mai hana ruwa shiga sau 3×, sannan a busar da shi a cikin injin cire datti (CaCl₂) na tsawon awanni da yawa.
Yawan amfani: 29.4 g na ≥98% NaHS tsantsa.
