    Kugwiritsa ntchito

    1.Amagwiritsidwa ntchito popanga mankhwala ophera tizilombo ndi acaricide monometamidine ndi bimetamidine.
    2.Amagwiritsidwanso ntchito popanga mankhwala, zikopa zopangira, zikopa zopangira ndi mankhwala osungunulira nsalu za fiber.

    Kusungirako

    Zosungirako zotsekedwa kuti ziteteze kutayikira, kupewa mvula, kukhudzidwa, kukhudzidwa kwambiri ndi mikangano.

    Khalani kutali ndi gwero la moto ndi kutentha.

    Kukhazikika

    1. Mafuta amadzimadzi osawoneka bwino osawoneka bwino.
    Amasungunuka m'madzi ndipo amathanso kusungunula mchere wachilengedwe.
    Ndi hygroscopic ndipo amawola mosavuta mu acidic kapena alkaline solution.
    Kununkhira kwa ammonia.

    Mankhwalawa amalumikizana ndi hydrogen chloride kupanga mitundu iwiri ya mchere;
    HCONHCH3 · HCl imapangidwa muzitsulo zopanda polar;
    (HCONHCH3)2·HCl imapangidwa popanda zosungunulira.
    Zilibe pafupifupi mphamvu ndi sodium zitsulo pa firiji.
    Hydrolysis imachitika pansi pa zochita za asidi kapena zamchere.
    Mlingo wa acidic hydrolysis ndi formamide>N-methylformamide>N,N-dimethylformamide.
    Mlingo wa alkaline hydrolysis ndi formamide-N-methylformamide>N,N-dimethylformamide.

    2. Kukhala mu utsi wamba.
