Zothandiza
● Makalasi a Mankhwala: Ma Nayitrojeni Masamba -> Masamba a Urea
● Canonical SMILES: CNC(=O)NC
● Kuopsa Kokoka mpweya: Palibe zisonyezo za kuchuluka kwa kuchuluka kwa mankhwalawa mumpweya.
● Zotsatira za Kuwonetsedwa Kwakanthawi kochepa: Mankhwalawa amawononga pang'ono m'maso ndi pakhungu.
● Kufotokozera: 1, 3-Dimethylurea ndi yochokera ku urea ndipo imagwiritsidwa ntchito ngati gawo lapakati pakupanga organic.Ndi ufa wa crystalline wopanda mtundu wokhala ndi kawopsedwe kakang'ono.Amagwiritsidwanso ntchito popanga caffeine, mankhwala opangira mankhwala, zovala zothandizira, mankhwala a herbicides ndi zina.M'makampani opanga nsalu 1,3-dimethylurea imagwiritsidwa ntchito ngati yapakatikati popanga zida zomalizitsira nsalu zopanda formaldehyde.Mu Swiss Product Register muli zinthu 38 zomwe zili ndi 1,3-dimethylurea, pakati pawo zinthu 17 zomwe zimagwiritsidwa ntchito ndi ogula.Mitundu ya mankhwala ndi monga utoto ndi zoyeretsera.Zomwe zili mu 1,3-dimethylurea muzinthu zogula ndi 10% (Swiss Product Register, 2003).Kugwiritsiridwa ntchito muzodzoladzola kwaperekedwa, koma palibe chidziwitso chogwiritsidwa ntchito pazochitika zoterezi.1,3-Dimethylurea ndi organic compound ndi formula (CH3) 2NC (O) NH2.Ndi kristalo wopanda mtundu wolimba komanso wosungunuka kwambiri m'madzi.1,3-Dimethylurea imagwiritsidwa ntchito ngati chosungunulira komanso chothandizira mu organic synthesis.Itha kugwiritsidwa ntchito popanga zinthu zosiyanasiyana monga utoto, utoto wa fulorosenti, ndi mapulasitiki.M'makampani opanga mankhwala, 1,3-dimethylurea imagwiritsidwanso ntchito popanga mankhwala apakati.Kuphatikiza apo, amagwiritsidwa ntchito m'mafakitale monga zokutira ndi zomatira.Ndikofunika kuzindikira kuti 1,3-dimethylurea imakwiyitsa khungu ndi maso, choncho njira zoyenera zotetezera ziyenera kuchitidwa pogwira.
● Ntchito: N,N′-Dimethylurea ingagwiritsidwe ntchito:Monga poyambira kupanga N,N′-dimethyl-6-amino uracil.Kuphatikizana ndi zotumphukira za β-cyclodextrin, kupanga zosakaniza zotsika kwambiri (LMMs), zomwe zitha kugwiritsidwa ntchito ngati zosungunulira za hydroformylation ndi zochita za Tsuji-Trost. Biginelli condensation pansi pa mikhalidwe yopanda zosungunulira.
