Chofunika
● Maphunziro a zamankhwala: Nayirogen Mankhwala -> Urea Coments
● Kumwetulira kwa canical: CN (c) c (= o) n (c) c
● Kugwiritsa ntchito: Tetramethylurea imagwiritsidwa ntchito ngati soltwiff mafakitale, munthawi yophatikiza komanso pakati pazinthu zowonjezera. Imagwiritsidwa ntchito ngati maziko a isomazation ndi alkylation hydrocation chifukwa chololedwa. Imayankha ndi oxalyl chloride kukonza tetramethy chloroformamidium chlorilic, yomwe imagwiritsidwa ntchito potembenuza kwa carboxylic ads ndi pyrophossophate motsatana.
1,1,3-Tetramethylurea, omwe amadziwikanso kuti TMU kapena n, n, n ' Ndiwokhazikika kwambiri yomwe imasungunuka kwambiri m'madzi ndi por solant.Twa imagwiritsidwa ntchito kwambiri ngati zosungunulira komanso zosintha m'mankhwala osiyanasiyana. Kusungunuka kwake kwakukulu ndi kuwopsa kochepa kumapangitsa kuti osungunuka omwe amakonda kugwiritsa ntchito njira zomwe zimawonjezera, catalysis, komanso monga momwe amachitira ndi kapangidwe kake. Itha kugwiritsidwanso ntchito kusungunula zinthu zachilengedwe zomwe sizimasungunuka mu ma sol solsorts.similar kupita ku Urea, TMU imatha kukhala ngati Wopereka Mphamvu ya Hydrogen, yomwe imapangitsa kuti ikhale yothandiza m'masinthidwe osiyanasiyana. Amakhala olemba ntchito ku Peptide synthesis, zokhudzana ndi zitsulo, ndipo monga momwe amachitire mosadukiza mu kafukufuku wamankhwala.
