Hoʻohana
Ua hoʻohana ʻia ʻo 1,1-Dimethylurea (N, N-dimethylurea) i ka Dowex-50W ion exchange resin-promote synthesis o N,N′-disubstituted-4-aryl-3,4-dihydropyrimidinones.1,1-Dimethylurea. he pūhui ʻokoʻa me ke kumu kemika (CH3)2NC(O)NH(CH3).ʻIke ʻia ʻo ia ʻo dimethyl carbamide a i ʻole N,N'-dimethylurea.1,1-Dimethylurea he paʻa kristal keʻokeʻo a hiki ke hoʻoheheʻe ʻia i ka wai.Hoʻohana mua ʻia ʻo ia ma ke ʻano he reagent i ka synthesis organik, kūikawā i ka hoʻomākaukau ʻana i nā lāʻau lapaʻau a me nā agrochemical.Hiki iā ia ke komo i nā hopena like ʻole e like me ka amidations, carbamoylations, a me nā condensations.Eia kekahi, hiki i ka 1,1-dimethylurea ke hana ma ke ʻano he mea hoʻoheheʻe no nā mea polar. E like me kekahi hui kemika, pono e mālama pono i ka mālama ʻana i ka 1,1-dimethylurea, me ka hoʻohana ʻana i nā mīkina lima kūpono, nā maka aniani, a me ka ea kūpono.Pono e ʻimi i ka pepa ʻikepili palekana (SDS) a e hahai i nā kaʻina hana i ʻōlelo ʻia a me ka hoʻokuʻu ʻana.
