Waxtar leh
Fasalada kiimikada: xeryahooda nitrogen -> xeryahooda urea
● dhoola cadeynta canonical: cn (c) c (= o) n (c) c
● Isticmaalka: Tetramethylurea waxaa loo istcimaalayaa sidii solteven oo ku saabsan warshadaha DyestAff, oo falcelinta uumiga iyo isdhaafsiga dusha sare. Waxaa loo adeegsadaa salka saldhigga loo yaqaan 'murxing' iyo hydrocyation hydrocyan oo ay ugu wacan tahay mushaharkeeda hoose. Waxay ka falcelineysaa chloride chloride si loo diyaariyo tetrametyl chloroformamium, oo loo isticmaalo beddelka aashitada carbboxylic-ka iyo prosphosphphes-ka candhuucadaha iyo pyrophosphphiespherkaaga siday u kala horreeyaan.
1,1,3,3-Tetramethyrea, oo sidoo kale loo yaqaan TMU ama n, n ', n', n'-tetrameyluea, waa xarun kiimiko ah oo leh noocyada molikalal cáh14n2n2o. Waa adag oo Crystalline ah oo aad u milatatay biyo iyo xabago kale oo xunxun. Xoolaha sare iyo sunta hoose waxay ka dhigeysaa xallin xallinta codsiyada sida geedi socodka soosaarka, cunsuriyada, iyo sidii dhexdhexaad falcelin loogu talagalay isku-darka dabiiciga ah ee isku-darka dabiiciga ah. Waxaa sidoo kale loo isticmaali karaa in lagu baabi'iyo xeryahooda dabiiciga ah ee ka yar ku -furan solvents kale. Waxaa caadi ahaan loo shaqeeyaa PetTidesis, falcelinta birta-soo-saarta, iyo mid jawaab celin ah oo ku saabsan cilmi-baarista dawooyinka.
