Inkcazo yeMveliso ye-DIMETHYLUREA
I-1,1-Dimethylurea i-chemical compound kunye ne-molecular formula C3H8N2O.Ikwabizwa ngokuba yi-dimethylurea okanye i-DMU.Ingumgubo omhlophe wekristale, unyibilika ngokulula emanzini kunye nezinyibilikisi eziphilayo.
I-1,1-Dimethylurea inezicelo ezahlukeneyo kumashishini ahlukeneyo.Enye yezona zinto zisetyenziswayo njenge-reagent kwi-organic synthesis.Ngokuqhelekileyo isetyenziswe njengomthombo we-dimethylamine, ibhloko ebalulekileyo yokwakha ekuveliseni amayeza, idayi kunye nezinye iikhemikhali.
Kwishishini lamachiza, i-1,1-dimethylurea isetyenziswa njenge-precursor ye-synthesis yamachiza kunye ne-intermediates yeziyobisi.
Ingasetyenziswa njenge-arhente ekhuselayo kumaqela asebenzayo ekhemikhali ngexesha lokusabela kwezinto eziphilayo.Ikwasetyenziswa njenge-catalyst kwiimpendulo ezithile.
Ukongezelela, i-1,1-dimethylurea iphinda isetyenziswe kwi-synthesis ye-herbicides kunye ne-fungicides.Isebenza njenge-stabilizer kwaye iphakamisa ukusebenza kwezi khemikhali ze-agrochemicals.Kubaluleke kakhulu ukuphatha i-1,1-dimethylurea ngokunyamekela kuba ithathwa njengeyingozi xa ifakwe okanye idibene nesikhumba okanye amehlo.Kufuneka kuthathwe amanyathelo okhuseleko afanelekileyo xa usebenza nale khompawundi, njengokunxiba izixhobo zokukhusela nokuqinisekisa ukungena komoya kakuhle.
Isishwankathelo, i-1,1-dimethylurea yi-multifunctional compound enokuthi isetyenziswe kwi-organic synthesis, i-pharmaceuticals, kunye ne-agrochemicals.Iimpawu zayo zenza ukuba luncedo njenge-reagent, isikhuseli, kunye ne-catalyst kwiinkqubo ezahlukeneyo zeekhemikhali.

Ukusetyenziswa kwe-DIMETHYLUREA kunye ne-Synthesis
| Iipropati zeMichiza | Umgubo wekristale omhlophe ukuya kumhlophe |
| Usebenzisa | 1,1-Dimethylurea (N,N-dimethylurea) isetyenziswe kwi-Dowex-50W ion exchange resin-promoted synthesis ofN,N'-disubstituted-4-aryl-3,4-dihydropyrimidinones. |
| Inkcazo ngokubanzi | Iipropati ze-Optical ezingabonakaliyo ze-1,1-dimethylurea (N,N′i-dimethylurea), ziye zavavanywa ngesizukulwana sesibini se-harmonic. |
| Ukutsha kunye nokuSebenza | Aluhlelwanga |
