Faa'iido leh
● Fasalada Kiimikada: Isku-dhafka Nitrojiinka -> Isku-dhafka Urea
Dhoola-cadaynta Canonical: CNC(=O)NC
● Khatarta Neefsashada: Wax calaamad ah lagama bixin karo heerka ay gaadho fiirsashada waxyeellada leh ee walaxdan hawada ku jirta.
● Saamaynta Soo-gaadhista Muddada Gaaban: Walaxda ayaa si khafiif ah uga xanaajisa indhaha iyo maqaarka.
● Sharaxaad: 1, 3-Dimethylurea waa urea ka soo saarta waxaana loo istcimaalaa dhex dhexaad ka mid ah isku dhafka organic.Waa budo crystalline ah oo aan midab lahayn oo leh sun yar.Waxa kale oo loo isticmaalaa isku-darka kafeyn, kiimikooyinka farmashiyaha, qalabyada dunta, herbicides iyo kuwa kale.Warshadaha farsamaynta dharka 1,3-dimethylurea waxa loo istcimaalaa dhex dhexaad ka ah soo saarista walaxaha dhamaystirka daryeelka fudud ee formaldehyde-free ee dharkaDiiwaanka alaabta Swiss waxaa ku jira 38 badeeco oo ka kooban 1,3-dimethylurea, oo ay ka mid yihiin 17 badeecooyin loogu talagalay isticmaalka macaamiisha.Noocyada alaabadu waa tusaale rinji iyo walxaha nadiifinta.Waxa ku jira 1,3-dimethylurea ee alaabta macmiisha ah waa ilaa 10 % (Diiwaanka Alaabta Swiss, 2003).Isticmaalka waxyaabaha la isku qurxiyo ayaa la soo jeediyay, laakiin ma jiraan wax macluumaad ah oo la heli karo oo ku saabsan isticmaalka dhabta ah ee codsiyadaas.1,3-Dimethylurea waa isku-darka organic oo leh caanaha (CH3) 2NC (O) NH2.Waa crystalline adag oo aan midab lahayn oo leh milmi sare oo biyo ah.1,3-Dimethylurea waxaa caadi ahaan loo isticmaalaa sida dareere iyo kicinta isku-dhafka organic.Waxaa loo isticmaali karaa isku-dhafka xeryahooda kala duwan sida dheeha, midabada fluorescent, iyo balaastikada.Warshadaha dawooyinka, 1,3-dimethylurea ayaa sidoo kale loo isticmaalaa in lagu soo saaro qaar ka mid ah dhexdhexaadiyeyaasha dawooyinka.Intaa waxaa dheer, waxaa loo isticmaalaa warshadaha sida dahaarka iyo xabagta.Waxaa muhiim ah in la ogaado in 1,3-dimethylurea ay ka xanaajiso maqaarka iyo indhaha, markaa taxaddarrada badbaadada saxda ah waa in la qaadaa marka la xakameynayo.
● Isticmaalka: N, N'-Dimethylurea waxaa loo isticmaali karaa: Wax bilow ah si loo farsameeyo N, N'-dimethyl-6-amino uracil.Marka lagu daro β-cyclodextrin derivatives, si ay u sameeyaan isku-dhafka hoose ee dhalaalka (LMMs), kaas oo loo isticmaali karo sida dareerayaasha loogu talagalay hydroformylation iyo falcelinta Tsuji-Trost. Uumiga Biginelli ee hoos yimaada xaaladaha aan dareeraha lahayn.
