DimethylureCrea, tseem hu ua n, n-dmu, yog cov organic sib xyaw nrog cov mis (ch3) 2nconh2. Nws yog xim tsis muaj xim crystalline khoom, soluble hauv dej thiab cov kuab tshuaj organic. DimethylureAtle tau siv nyob rau hauv ntau cov ntawv thov kev lag luam, suav nrog raws li cov kuab tshuaj, tshuaj lom neeg nrab, thiab catalyst. Raws li cov kuab tshuaj, dimethylurea feem ntau siv nyob rau hauv kev tsim ntawm ntau yam kev ua ntau yam, tsho tshaj thiab polymers. Nws nce cov solubility thiab viscosity ntawm cov ntaub ntawv no, ua rau lawv yooj yim rau cov txheej txheem thiab thov. Cov kev daws plawv ntawm dimethylurea tseem ua rau nws yaj tag nrho cov organic thiab inorganic sib xyaw, ua rau nws muaj txiaj ntsig zoo hauv ntau cov tshuaj lom neeg. Nyob rau hauv cov nqe lus ntawm cov tshuaj synthesis, dimethylureCrea feem ntau siv los ua ib tug reactant lossis catalyst hauv ntau yam kev hloov pauv. Nws tuaj yeem koom nrog hauv synthesis ntawm carbamate, ownocyanate thiab lwm yam, thiab lwm yam, dimethylurehyde nyob rau qee cov kev tshua zoo li cov kev tawm tsam mansich. Dimethylurea tseem siv nyob rau hauv kev lag luam kws tshuaj. Nws tuaj yeem siv los ua qhov reagent rau cov khoom siv hluav taws xob ntawm cov tshuaj lwg me me, nrog rau kev npaj khoom lag luam. Tsis tas li ntawd, nws tseem tau kawm ua cov tshuaj yuav nws tus kheej, tshwj xeeb rau nws cov peev xwm tiv thaiv kab mob thiab cov tshuaj tua kab mob. Nws yog ib qho tseem ceeb heev los coj dimethylurea nrog kev saib xyuas dim vim tias nws yuav ua rau cov tawv nqaij, ob lub qhov muag, thiab ua pa. Muaj peev xwm cua txaus thiab cov khoom tiv thaiv tus kheej yuav tsum tau siv thaum ua haujlwm nrog cov compound no. Cia yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav qhov chaw kom deb ntawm hluav taws lossis ncaj qha hnub ci. Nco ntsoov tias cov ntaub ntawv nthuav tawm ntawm no yog cov kev qhia dav dav ntawm dimethylie thiab nws cov ntawv thov tau thiab ceev faj tuaj yeem yog
