    Daim ntawv thov

    1.Nws yog siv nyob rau hauv cov synthesis ntawm tshuaj tua kab thiab acaricide monometamidine thiab bimetamidine.
    2.Nws kuj yog siv rau hauv kev tsim tshuaj, hluavtaws tawv, tawv tawv thiab tshuaj fiber ntau textile hnyav.

    Cia

    Kev kaw cia kom tiv thaiv kom tsis txhob yaig, tsis txhob los nag, raug, cuam tshuam loj heev thiab kev sib txhuam.

    Khaws kom deb ntawm qhov hluav taws kub thiab cua sov.

    Kev ruaj ntseg

    1. Colorless pob tshab viscous oily kua.
    Nws yog soluble hauv dej thiab tuaj yeem yaj cov ntsev inorganic.
    Nws yog hygroscopic thiab yooj yim decomposes nyob rau hauv acidic los yog alkaline daws.
    Nws tsw ntawm ammonia.

    Cov khoom siv tshuaj muaj kev cuam tshuam nrog hydrogen chloride los ua ob hom ntsev;
    HCONHCH3 · HCl yog tsim nyob rau hauv cov kuab tshuaj tsis-polar;
    (HCONHCH3) 2 · HCl yog tsim tsis muaj kuab tshuaj.
    Nws yuav luag tsis muaj kev cuam tshuam nrog sodium hlau ntawm chav tsev kub.
    Hydrolysis tshwm sim nyob rau hauv qhov kev txiav txim ntawm acid los yog alkali.
    Cov acidic hydrolysis tus nqi yog formamide> N-methylformamide> N, N-dimethylformamide.
    Tus nqi alkaline hydrolysis yog formamide-N-methylformamide> N, N-dimethylformamide.
