    Ukupanga amenshi ya sodium ukupitila mu kunwa kwa NaOH

    2025-08-14

    Inshila iyaishibikwa iya kunwamo NaOH

    Ilyo umusango wa NaHS uwa menshi ya mulilo wafika 70%, cipanga ifiputulwa fya menshi ayabili.

    Pa fipimo ifinono, ciba nga amenshi yatatu aya menshi.

    Ubutantiko:

    Icipe ca 1 L ica mikonko itatu icashinguluka ica panshi cikwata ica kusansabika no kusansabika ica kubwesha (icasuntinkanishiwa ku cipe ca kuumishishamo ica CaCl2).

    Ici cipe cilasanguluka na nitrogen iyauma, lyena cilabikwamo na . 200 mililita (3.4 mol) iya bwalwa ubushakwata amenshi.

    12 g (0.522 mol) iya cimuti ca sodium ica busaka ilasangwa mu fiputulwa ifinono pa nshi ya kusansabika no kubwesha ukufikila yasunguluka fyonse.

    Icipe ca kwingililamo umulilo cibikwa mu menshi, kabili H2S iyauma (iyauma pa P2O5) ilapuupuutuka pa 5-10 ifipuupu / sec pa 2 h ukusansa.

    Pa numa ya kutonta, 750 mL iya ether iyabula amenshi ilalundwako ku kulenga NaHS ukutonta umupwilapo.

    Ukubomba:

    Ukusankanya kulasendwa bwangu bwangu (ukusankanya kwakosa) pa kuti umutonshi uleke ukunwa.

    Ici cikosa cilasambilwa 3× na ether uushakwata amenshi, lyena ciumikwa mu cipe ca kufimbapo (CaCl2) pa maawala ayengi.

    Ukusanga: 29.4 g iya ≥98% iya NaHS iya busaka.

    Iciputulwa ca menshi ica sodium caliba ica nshita itali ica kupeela ifya kulya pa myaka ukucila pali 20. Tinikeni pakuti mukwate amashiwi ayacefiwako.
