Chofunika
● Maphunziro a zamankhwala: Nayirogen Mankhwala -> Urea Coments
● Kumwetulira kwa canical: CNC (= O) NC
● Kupumula pa chiopsezo: Palibe chisonyezo chomwe chingaperekedwe ndi kuchuluka komwe kudalirika kwa chinthu ichi.
● Zokhudza kuwonekera kwa nthawi yayifupi: Zinthu zimakwiyitsa kwambiri maso ndi khungu.
● Kufotokozera: 1, 3-dimethylurea ndi urea wochokera ku urea ndikugwiritsa ntchito ngati gawo lapakati pa synthesis. Ndi ufa wopanda mitundu yopanda utoto ndi kawopsedwe kakang'ono. Amagwiritsidwanso ntchito ngati kaphatikizidwe wa khofi, mafakitale, ma Ediania a Edzi, herbicides ndi ena. Mu makampani opanga malembawo 1,3-dimethylurea amagwiritsidwa ntchito ngati wapakatikati popanga othandizira osasamala a Formalyer-chisamaliro. Mu Recorge Recotion Publing Pali zinthu 38 zomwe zili ndi 1,3-dimethylurea, pakati pawo zinthu zomwe zidafuna kugwiritsa ntchito ogula. Mitundu yazogulitsa ndi yopanga zotupa ndi zoyeretsa. Zomwe zili m'ma 1,3-dimethylurea muzogulitsa za ogula zili mpaka 10% (Chumara Register Registern, 2003). Gwiritsani ntchito zodzikongoletsera zafunsidwa, koma palibe zambiri zomwe zimapezeka pakugwiritsa ntchito kwake pa ntchitoyi.1,3-dimethylurea ndi gawo lolinganiza ndi formula (Ch3) 2nc (o) zh2. Ndiwokhazikika kopanda utoto ndi kusungunuka kwambiri m'madzi. 1,3-Dimethylurea nthawi zambiri amagwiritsidwa ntchito ngati zosungunulira komanso zothandizira mu kapangidwe kake. Itha kugwiritsidwa ntchito mu kapangidwe kazinthu zosiyanasiyana ngati utoto, utoto wa fluorests, ndi mapulasipi. M'makampani opanga mankhwala, 1,3-dimethylurea amagwiritsidwanso ntchito potengera mtundu wina wa mankhwala apakatikati. Kuphatikiza apo, imagwiritsidwa ntchito m'mafakitale monga zomatira ndi zomatira. Ndikofunikira kudziwa kuti 1,3-dimethylurea ikukwiyitsa khungu ndi maso, moyenera mosamala kuyenera kutengedwa mukamagwira.
● Kugwiritsa ntchito: N, N'-Nimethylurea zitha kugwiritsidwa ntchito: monga choyambira kuphatikizika N, N'-Amimethyl-6-amino UCHIVEL. Kuphatikiza ndi β-cyclodextrin, kuti mupange zosakaniza zosungunuka (LMMs), zomwe zingagwiritsidwe ntchito ngati ma solroformatlation ndi tsujini, 3-Aryl-3,4-Dihdropyridididididididididididididiation.
