    Isticmaalka Dimethylurea iyo Synthesis

    Sharaxaada 1, 3-Dimethylurea waa urea ka soo saarta waxaana loo isticmaalaa sidii dhex dhexaad u 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 macluumaad la heli karo oo ku saabsan isticmaalkeeda dhabta ah ee codsiyadan.
    Guryaha Kiimikada kiristaalo cad
    Adeegsada N,N"Dimethylurea waxaa loo isticmaali karaa:

    • Sida walxaha bilawga ah ee la isku dhejiyoN,N"-dimethyl-6-amino uracil.
    • Marka lagu daro β-cyclodextrin derivatives, si ay u sameeyaan isku-darka dhalaalka hooseeya (LMMs), kaas oo loo isticmaali karo sida dareeraha loogu talagalay hydroformylation iyo falcelinta Tsuji-Trost.
    • In la soo saaroN,N′-lagu khilaafay-4-aryl-3,4-dihydropyrimidines iyada oo loo sii marayo uumi-Biginelli ee hoos yimaada xaaladaha dareeraha-free.

     

    Qeexid ChEBI: Xubin ka tirsan fasalka ureas oo ah urea oo ay ku beddelaan kooxaha methyl ee jagooyinka 1 iyo 3.
    Sharaxaada Guud Kiristaalo aan midab lahayn.
    Falcelinta Hawada & Biyaha Biyo milmaya.
    Muuqaalka falcelinta 1,3-Dimethylurea waa amide.Amides/imides waxay la falgalaan azo iyo diazo xeryahooda si ay u dhaliyaan gaas sun ah.Gaasaska guban kara waxay ku abuurmaan falcelinta amides organic/imides oo leh walxo dhimis xooggan.Amides waa saldhigyo aad u daciif ah (ka daciifsan biyaha).Imides wali way ka yar yihiin aasaaska waxayna dhab ahaantii la falgalaan saldhigyo adag si ay u sameeyaan cusbo.Taasi waa, waxay uga falcelin karaan sida acids.Isku darka amides iyo wakiilada fuuqbaxa sida P2O5 ama SOCl2 waxay abuurtaa nitrile u dhigma.Gubashada xeryahooda waxay abuuraan oksaydhyo isku dhafan oo nitrogen ah (NOx).
    Khatar Caafimaad Khataraha aadka u daran: Marka la kululeeyo si loo kala furfuro 1,3-Dimethylurea waxay sii daysaa qiiq sun ah.
    Khatarta Dabka Xogta dhibicda Flash ee 1,3-Dimethylurea lama heli karo;1,3-Dimethylurea waxay u badan tahay inay guban karto.
    Xogta Badbaadada Sume dhexdhexaad ah iyadoo loo marayo marinka intraperitoneal.Tijaabada teratogenic iyo saamaynta taranka.Xog-is-beddelka aadanaha ayaa la sheegay.Marka la kululeeyo si uu u burburo waxa ay sii deysaa qiiq sun ah oo NOx ah
    Hababka Sifaynta Kaadi kariimka kaadida acetone/diethyl ether adiga oo ku qaboojinaya qubeyska barafka.Sidoo kale ka soo miir EtOH oo ku qalaji 50o/5mm 24saacadood [Bloemendahl & Somsen J Am Chem Soc 107 3426 1985].[Beilstein 4 IV 207.]
