● Pilikia Inhalation: ʻAʻole hiki ke hāʻawi ʻia kahi hōʻailona e pili ana i ka nui o ka loaʻa ʻana o kahi ʻano ʻino o kēia mea i ka lewa.
● Nā hopena o ka hōʻike ʻana no ka wā pōkole: ʻoluʻolu ka mea i hoʻonāukiuki i ka maka a me ka ʻili.
● Hōʻike: 1, 3-Dimethylurea he urea derivative a hoʻohana ʻia ma ke ʻano he waena i ka synthesis organik.He pauda crystalline kala ʻole me ka ʻona liʻiliʻi.Hoʻohana ʻia ia no ka synthesis o ka caffeine, pharmachemical, textile aids, herbicides a me nā mea ʻē aʻe.I ka ʻoihana hana textile, hoʻohana ʻia ʻo 1,3-dimethylurea ma ke ʻano he waena no ka hana ʻana i nā mea hoʻopau maʻalahi maʻalahi formaldehyde no ka textiles.I loko o ka Swiss Product Register aia nā huahana 38 i loaʻa ka 1,3-dimethylurea, ma waena o lākou he 17 huahana i manaʻo ʻia no ka hoʻohana ʻana i ka mea kūʻai.ʻO nā ʻano huahana e laʻa me nā pena a me nā mea hoʻomaʻemaʻe.ʻO ka ʻike o 1,3-dimethylurea i nā huahana mea kūʻai aku a hiki i 10% (Swiss Product Register, 2003).Hoʻohana ʻia i nā mea hoʻonaninani, akā ʻaʻohe ʻike e pili ana i kona hoʻohana maoli ʻana i ia mau noi.He paʻa kalakala kala ʻole me ka solubility kiʻekiʻe i ka wai.Hoʻohana pinepine ʻia ʻo 1,3-Dimethylurea e like me ka solvent a me ka catalyst i ka synthesis organik.Hiki ke hoʻohana ʻia i ka synthesis o nā pūhui like ʻole e like me nā dyes, fluorescent dyes, a me nā plastics.I ka ʻoihana lāʻau lapaʻau, hoʻohana pū ʻia ʻo 1,3-dimethylurea e synthesize i kekahi mau intermediates pharmaceutical.Eia kekahi, hoʻohana ʻia i nā ʻoihana e like me nā uhi a me nā mea hoʻopili.He mea nui e hoʻomaopopo i ka 1,3-dimethylurea e hoʻonāukiuki i kaʻili a me nā maka, no laila pono e mālama pono i ka mālamaʻana.
● Hoʻohana: N,N′-Dimethylurea hiki ke hoʻohana: Ma ke ʻano he mea hoʻomaka e synthesize N,N′-dimethyl-6-amino uracil.I ka hui pū ʻana me β-cyclodextrin derivatives, e hana i nā hui hoʻoheheʻe haʻahaʻa (LMMs), hiki ke hoʻohana ʻia e like me nā solvents no ka hydroformylation a me Tsuji-Trost reactions. ʻO Biginelli condensation ma lalo o nā kūlana solvent-free.
