Siv
1,1-Dimethylurea (N, N-dimethylurea) tau siv hauv Dowex-50W ion exchange resin-promoted synthesis ntawm N, N′-disubstituted-4-aryl-3,4-dihydropyrimidinones.1,1-Dimethylurea yog ib qho sib txawv nrog cov tshuaj formula (CH3)2NC(O)NH(CH3).Nws tseem hu ua dimethyl carbamide los yog N, N'-dimethylurea.1,1-Dimethylurea yog dawb crystalline khoom thiab soluble hauv dej.Nws yog feem ntau siv los ua ib qho reagent hauv cov organic synthesis, tshwj xeeb hauv kev npaj cov tshuaj thiab agrochemicals.Nws tuaj yeem koom nrog ntau yam kev cuam tshuam xws li amidations, carbamoylations, thiab condensations.Tsis tas li ntawd, 1,1-dimethylurea tuaj yeem ua cov kuab tshuaj rau cov polar tshuaj.Zoo li nrog rau cov tshuaj lom neeg, kev ceev faj txog kev nyab xeeb yuav tsum tau ua thaum tuav 1,1-dimethylurea, nrog rau kev siv cov hnab looj tes tsim nyog, tsom iav, thiab qhov cua txaus.Nws yog ib qho tseem ceeb uas yuav tau tham txog daim ntawv pov thawj kev nyab xeeb (SDS) thiab ua raws li cov txheej txheem tuav thiab pov tseg.
