Iwusizo
● Amakilasi Amakhemikhali: Ama-Nitrogen Compounds -> Ama-Urea Compounds
● I-Canonical SMILES: CNC(=O)NC
● Ingozi Yokuhogela: Akukho nkomba enganikezwa ngezinga okufinyelelwa ngalo ukuhlangana okuyingozi kwalo muthi osemoyeni.
● Imithelela Yokuchayeka Kwesikhashana: Lo muthi uyacasula kancane emehlweni nasesikhumbeni.
● Incazelo: I-1, i-3-Dimethylurea iphuma e-urea futhi isetshenziswa njengendawo emaphakathi ekuhlanganiseni kwe-organic.Kuyimpushana ecwebezelayo engenambala enobuthi obuncane.Ibuye isetshenziselwe ukuhlanganiswa kwe-caffeine, amakhemikhali, izinsiza zendwangu, ama-herbicides nezinye.Embonini yokucubungula izindwangu i-1,3-dimethylurea isetshenziswa njengendawo emaphakathi ukuze kukhiqizwe ama-ejenti aqeda ukunakekela okulula angenayo i-formaldehyde yendwangu.Kurejista yomkhiqizo waseSwitzerland kunemikhiqizo engama-38 equkethe i-1,3-dimethylurea, phakathi kwayo imikhiqizo eyi-17 ehloselwe ukusetshenziswa ngabathengi.Izinhlobo zemikhiqizo ziyisibonelo, amapende nama-ejenti okuhlanza.Okuqukethwe kwe-1,3-dimethylurea emikhiqizweni yabathengi kufika ku-10 % (Irejista Yomkhiqizo yase-Swiss, 2003).Ukusetshenziswa kwezimonyo kuhlongozwa, kodwa alukho ulwazi olutholakalayo mayelana nokusetshenziswa kwayo kwangempela kuzicelo ezinjalo.I-1,3-Dimethylurea iyinhlanganisela ephilayo enefomula (CH3)2NC(O)NH2.Kuyikristalu eqinile engenambala nokuncibilika okuphezulu emanzini.I-1,3-Dimethylurea ivame ukusetshenziswa njenge-solvent kanye ne-catalyst ku-organic synthesis.Ingasetshenziswa ekuhlanganiseni izinhlanganisela ezihlukahlukene ezifana nodayi, odayi be-fluorescent, namapulasitiki.Embonini yezemithi, i-1,3-dimethylurea iphinde isetshenziselwe ukuhlanganisa ezinye izixhumanisi zemithi.Ngaphezu kwalokho, isetshenziswa ezimbonini ezifana nama-coatings nama-adhesives.Kubalulekile ukuqaphela ukuthi i-1,3-dimethylurea iyacasula esikhumbeni nasemehlweni, ngakho kufanele kuthathwe izinyathelo zokuphepha ezifanele lapho uphathwa.
● Ukusetshenziswa: I-N,N′-Dimethylurea ingasetshenziswa:Njengento yokuqala yokwenza i-N,N′-dimethyl-6-amino uracil.Ngokuhambisana nokuphuma kwe-β-cyclodextrin, ukwakha izingxube zokuncibilika okuphansi (ama-LMM), angasetshenziswa njengezincibilikisi ze-hydroformylation kanye nokusabela kwe-Tsuji-Trost. I-Biginelli condensation ngaphansi kwezimo ezingenazo i-solvent.
