Iluncedo
● Iiklasi zeMichiza: IiCompounds zeNitrojeni -> IiCompounds zeUrea
● Uncumo lweCanonical: CNC(=O)NC
● Umngcipheko wokuphefumla: Akukho salathisi sinokunikwa malunga nesantya ekufikelelwe ngaso ukugxininiswa okuyingozi kwalo nto emoyeni.
● Iimpembelelo zokuSebenza kwethuba elifutshane: Lo mxube ucaphukisa kancinci amehlo kunye nolusu.
● Inkcazo: I-1, i-3-Dimethylurea yi-urea derivative kwaye isetyenziswe njengendawo ephakathi kwi-organic synthesis.Ingumgubo wekristale ongenambala kunye netyhefu encinci.Ikwasetyenziselwa ukuhlanganiswa kwecaffeine, iikhemikhali, izixhobo ezilukiweyo, imichiza yokhula kunye nezinye.Kumashishini okulungisa amalaphu i-1,3-dimethylurea isetyenziswa njengendawo ephakathi kwimveliso ye-formaldehyde-free-free-care-care finishing agents for textiles.KwiRejista yeMveliso yaseSwitzerland kukho iimveliso ze-38 eziqukethe i-1,3-dimethylurea, phakathi kwazo iimveliso ze-17 ezijoliswe kubasebenzisi.Iintlobo zeemveliso umz. iipeyinti kunye neearhente zokucoca.Umxholo we-1,3-dimethylurea kwiimveliso zabathengi ukuya kwi-10% (iRejista yeMveliso yaseSwitzerland, i-2003).Ukusetyenziswa kwi-cosmetics kucetywayo, kodwa akukho lwazi olukhoyo malunga nokusetyenziswa kwayo kwangempela kwizicelo ezinjalo.1,3-Dimethylurea i-organic compound kunye ne-formula (CH3) 2NC (O) NH2.Yikristale engenambala eqinileyo kunye nokunyibilika okuphezulu emanzini.I-1,3-Dimethylurea isetyenziswa ngokuqhelekileyo njenge-solvent kunye ne-catalyst kwi-organic synthesis.Ingasetyenziswa ekudibaneni kweekhompawundi ezahlukeneyo ezifana nedayi, idayi yefluorescent, kunye neeplastiki.Kwishishini lamachiza, i-1,3-dimethylurea iphinda isetyenziswe ukudibanisa amanye ama-pharmaceutical intermediates.Ukongeza, isetyenziswa kumashishini afana neengubo kunye nokunamathiswa.Kubalulekile ukuba uqaphele ukuba i-1,3-dimethylurea iyacaphukisa ulusu kunye namehlo, ngoko kufuneka kuthathwe amanyathelo okhuseleko afanelekileyo xa uphatha.
● Ukusetyenziswa: I-N,N′-Dimethylurea ingasetyenziswa: Njengesixhobo sokuqala ukudibanisa i-N,N′-dimethyl-6-amino uracil.Ngokudibanisa ne-β-cyclodextrin derivatives, ukwenza imixube encibilikayo ephantsi (LMMs), engasetyenziselwa njenge-solvents ye-hydroformylation kunye ne-Tsuji-Trost reactions.Ukudibanisa i-N, N′-disubstituted-4-aryl-3,4-dihydropyrimidinones ngokusebenzisa I-Biginelli condensation phantsi kweemeko ezingenayo i-solvent.
