E aoga
● Vasega vaila'au: Fa'aputuga Nitrogen -> Fa'aupu Urea
● ATAATA Canonical: CNC(=O)NC
● Tulaga lamatia o le Inhalation: E leai se faʻamatalaga e mafai ona tuʻuina atu e uiga i le saoasaoa e oʻo atu ai se faʻalavelave leaga o lenei mea i le ea.
● A'afiaga o Va'aiga Puupuu: O le vaila'au e fa'afefe malie i mata ma le pa'u.
● Faʻamatalaga: 1, 3-Dimethylurea o se mea e maua mai i le urea ma faʻaaogaina e avea o se vaeluaga i le faʻaogaina o meaola.O se pauta tioata e leai se lanu ma sina oona itiiti.E faʻaaogaina foʻi mo le tuʻufaʻatasia o caffeine, vailaʻau, fesoasoani ie, herbicides ma isi.I totonu o le fale gaosi oloa 1,3-dimethylurea o loʻo faʻaaogaina e avea ma mea faʻapitoa mo le gaosiga o formaldehyde-saʻoloto-tausia faʻamaeʻaina sui mo ie.I le Suiselani o oloa Resitala o loʻo i ai 38 oloa o loʻo i ai le 1,3-dimethylurea, faʻatasi ai ma 17 oloa faʻamoemoe mo le faʻaaogaina e tagata faʻatau.O ituaiga oloa e pei o vali ma mea e fa'amamā ai.O mea o loʻo i totonu o le 1,3-dimethylurea i oloa faʻatau e oʻo atu i le 10% (Swiss Product Register, 2003).O le fa'aogaina i mea fa'alelei ua fa'atonuina, ae leai se fa'amatalaga o lo'o maua i lona fa'aoga moni i ia talosaga.1,3-Dimethylurea o se fa'alapotopotoga fa'alenatura ma le fua (CH3)2NC(O)NH2.Ose ma'a tioata e leai ni lanu ma maualuga solubility i le vai.1,3-Dimethylurea e masani ona faʻaaogaina e avea o se solvent ma le faʻamalosi i le faʻaogaina o meaola.E mafai ona faʻaaogaina i le faʻapipiʻiina o mea faʻapipiʻi eseese e pei o vali, lanu felanulanuaʻi, ma palasitika.I totonu o fale gaosi oloa, 1,3-dimethylurea o loʻo faʻaaogaina foi e faʻapipiʻi ai nisi vailaʻau vailaʻau.E le gata i lea, o loʻo faʻaaogaina i pisinisi e pei o paʻu ma faʻapipiʻi.E taua le maitauina o le 1,3-dimethylurea e faʻafefe i le paʻu ma mata, o lea e tatau ai ona faia ni puipuiga lelei pe a taulimaina.
● Fa'aoga: N,N′-Dimethylurea e mafai ona fa'aogaina: E fai ma mea amata e fa'aputu ai le N,N′-dimethyl-6-amino uracil.I le tu'ufa'atasia ma β-cyclodextrin derivatives, e fausia ai fa'afefiloi vaivai (LMMs), lea e mafai ona fa'aaogaina e fai ma solvents mo hydroformylation ma Tsuji-Trost reactions. To synthesize N,N′-disubstituted-4-aryl-3,4-dihydropyrimidinones e ala Biginelli condensation i lalo ole solvent-free condition.
