Khatarta Halista ah
Saamaynta soo-gaadhista muddada-gaaban: Maaddada ayaa si dhexdhexaad ah u xanaaqsan indhaha iyo maqaarka.
Tilmaanta: 1, 3-Dimthyluria ayaa ah mid ka mid ah ur-ka-qaadida una adeegsiga dhex-dhexaad u ah isku-darka dabiiciga ah. Waa budo aan midab lahayn oo midab leh oo leh sunta rasaasta yar. Waxaa sidoo kale loo isticmaalaa isku-darka kafeyn, farmasiiyo, aaladaha dharka, geedaha doogga iyo kuwa kale. Warshadaha dharka lagu sameeyo 1,3-Dimthyyluria waxaa loo istcimaalaa internater ay u tahay wax soo saarka wax soo saarka ee wakiilada dhammeystir la'aanta daryeelka-si sahlan ee loo adeegsado dharka. Diiwaanka sheyga Switzerland waxaa ku jira 38 alaab oo ay ku jiraan 1,3-Didethyluria, oo ka mid ah 17 badeecooyin loogu talagalay isticmaalka macaamiisha. Noocyada wax soo saarka ah waa sida tusaale ahaan rinjiyeynta iyo wakiilada nadiifinta. Waxyaabaha 1,3-Dimthyyluria ee ku jira wax soo saarka macaamiisha waa ilaa 10% (Diiwaanka sheyga Switzerland, 2003). U adeegsiga waxyaabaha la isku qurxiyo, laakiin ma jiro wax macluumaad ah oo loo adeegsado sida ugu habboon ee loo adeegsado codsiyada dhabta ah ee arjiyada noocaas ah.1 ,3-Dimthyyluea waa xarun dabiici ah oo leh qaaciddada (ch3) 2nc (o) nh2. Waa iskucelin aan midab lahayn oo adag oo sacab sare leh. 1,3-Dimthyyluria ayaa caadi ahaan loo istcimaalaa sidii solvent iyo cadey-ga oo ka dhaca isku-darka dabiiciga ah. Waxaa loo isticmaali karaa isku-darka isku-darka badan ee xarumaha kala duwan sida dhaqanka, dhalada iftiinka, iyo balaastigga. Warshadaha dawooyinka, 1,3-Dimthyyrea ayaa sidoo kale loo isticmaalaa in lagu saleeyo qaar ka mid ah dhexdhexaadinta dawooyinka qaarkood. Intaas waxaa sii dheer, waxaa loo isticmaalaa warshadaha sida jaakadaha iyo xargaha. Waxaa muhiim ah in la ogaado in 1,3-Dimthyluria ay xanaaq badan tahay maqaarka iyo indhaha, sidaa darteed taxaddarrada nabdoonaanta ee ku habboon waa in la qaataa marka la maareeyo.
● Isticmaalka: n, n'-dimumyylurea waxaa loo isticmaali karaa: sida arin bilow ah oo lagu saleeyo n, n'-jemthyl-6-amino uracil. Isku-darka waxyaabaha loo yaqaan 'β-Cy -cclodextrin', si loo sameeyo isku-dhafan hoose (lmmms), oo loo isticmaali karo solts-ka hydroformation iyo respubsizesize-ka-3-dyl-3-dyl-3,4-dyl -
