DIMETHYLUREA Kufotokozera Kwazinthu
1,1-Dimethylurea ndi mankhwala omwe ali ndi formula ya C3H8N2O.Amadziwikanso kuti dimethylurea kapena DMU.Ndi woyera crystalline ufa, mosavuta sungunuka m'madzi ndi organic solvents.
1,1-Dimethylurea ili ndi ntchito zosiyanasiyana m'mafakitale osiyanasiyana.Chimodzi mwazogwiritsidwa ntchito kwake ndi monga reagent mu organic synthesis.Nthawi zambiri amagwiritsidwa ntchito ngati gwero la dimethylamine, chinthu chofunikira kwambiri popanga mankhwala, utoto ndi mankhwala ena.
M'makampani opanga mankhwala, 1,1-dimethylurea imagwiritsidwa ntchito ngati kalambulabwalo wa kaphatikizidwe ka mankhwala ndi mankhwala apakatikati.
Itha kugwiritsidwa ntchito ngati woteteza kwa magulu okhudzidwa ndi mankhwala pamagulu achilengedwe.Amagwiritsidwanso ntchito ngati chothandizira pazochitika zina.
Kuphatikiza apo, 1,1-dimethylurea imagwiritsidwanso ntchito popanga mankhwala a herbicides ndi fungicides.Zimagwira ntchito ngati stabilizer ndikuwonjezera magwiridwe antchito a agrochemicals awa.Ndikofunika kwambiri kusamalira 1,1-dimethylurea mosamala chifukwa imatengedwa kuti ndi yovulaza ngati italowetsedwa kapena kukhudzana ndi khungu kapena maso.Njira zopewera chitetezo ziyenera kutsatiridwa pogwira ntchito ndi komputala iyi, monga kuvala zida zodzitetezera komanso kuonetsetsa kuti mpweya wabwino ukuyenda bwino.
Mwachidule, 1,1-dimethylurea ndi mankhwala ambiri omwe angagwiritsidwe ntchito mu organic synthesis, pharmaceuticals, ndi agrochemicals.Makhalidwe ake amapangitsa kuti ikhale yothandiza ngati reagent, chitetezo, komanso chothandizira pamachitidwe osiyanasiyana amankhwala.

Kugwiritsa Ntchito DIMETHYLUREA Ndi Kaphatikizidwe
| Chemical Properties | Ufa wa crystalline woyera mpaka woyera |
| Ntchito | 1,1-Dimethylurea (N,N-dimethylurea) yakhala ikugwiritsidwa ntchito mu Dowex-50W ion exchange resin-promoted synthesis ofN, N'-disubstituted-4-aryl-3,4-dihydropyrimidinones. |
| Kufotokozera Kwambiri | Zopanda mawonekedwe za 1,1-dimethylurea (N,N'dimethylurea), adawunikidwa kudzera mumbadwo wachiwiri waharmonic. |
