Whakamahinga
Kua whakamahia te 1,1-Dimethylurea (N,N-dimethylurea) i roto i te Dowex-50W ion exchange resin-promoted synthesis of N,N′-disubstituted-4-aryl-3,4-dihydropyrimidinones.1,1-Dimethylurea is he pūhui rerekē me te tātai matū (CH3)2NC(O)NH(CH3).Kei te mohiotia ano ko te dimethyl carbamide, ko N,N'-dimethylurea ranei.1,1-Dimethylurea he totoka tioata ma, ka whakarewahia ki te wai.Kei te whakamahia tuatahi hei reagent i roto i te whakahiato pararopi, inaa ki te whakareri i nga rongoa me nga matū ahuwhenua.Ka taea e ia te uru atu ki nga momo tauhohenga penei i te amidations, carbamoylations, me te condensations.I tua atu, ka taea e te 1,1-dimethylurea te mahi hei whakarewa mo nga matū polar. Pērā i ngā pūhui matū, me whai tūpato haumaru i te wa e whakahaere ana i te 1,1-dimethylurea, tae atu ki te whakamahi i nga karapu e tika ana, nga karaehe, me te hau tika.He mea nui ki te toro atu ki te pepa raraunga haumaru (SDS) me te whai i nga tikanga whakahaere me te whakakorenga kua tohua.
