Whai hua
● Karaehe matū: Puhui Nitrogen -> Puhui Urea
● ATA MAHI Canonical: CNC(=O)NC
● Morearea mo te Inhalation: Karekau he tohu e taea te whakaatu mo te tere e tae atu ai te kuhanga kino o tenei matū ki te hau.
● Nga Paanga o te Whakaaturanga Waa Poto: Ko te matū he mea whakapouri ki nga kanohi me te kiri.
● Whakaahuatanga: Ko te 1, 3-Dimethylurea he paheketanga Urea ka whakamahia hei takawaenga i roto i te whakahiato waro.He paura tioata kore tae he iti te paitini.Kei te whakamahia hoki mo te whakahiato o te kawhe, te rongoa, te awhina pueru, te patupatu me etahi atu.I roto i te ahumahi tukatuka kakano ka whakamahia te 1,3-dimethylurea hei takawaenga mo te hanga o nga apiha whakaoti ngawari-kore formaldehyde mo nga kakano.I roto i te Rehita Hua Swiss he 38 nga hua kei roto i te 1,3-dimethylurea, kei roto i a raatau nga hua 17 mo te whakamahi a nga kaihoko.Ko nga momo hua he tauira peita me nga taputapu horoi.Ko te ihirangi o te 1,3-dimethylurea i roto i nga hua kaihoko ka eke ki te 10 % (Swiss Product Register, 2003).Ko te whakamahi i roto i nga mea whakapaipai kua whakaarohia, engari karekau he korero e waatea ana mo tona tino whakamahinga i roto i aua tono.1,3-Dimethylurea he puhui waro me te tauira (CH3)2NC(O)NH2.He totoka karaihe kore tae me te wairewa nui ki te wai.Ko te 1,3-Dimethylurea e whakamahia ana hei whakarewa me te whakakorikori i roto i te whakahiato waro.Ka taea te whakamahi i roto i te whakahiatotanga o nga momo puhui penei i te waikano, te waikano rewharewha, me te kirihou.I roto i te ahumahi rongoa, ka whakamahia ano te 1,3-dimethylurea ki te whakahiato i etahi takawaenga rongoa.I tua atu, ka whakamahia i roto i nga ahumahi penei i te paninga me te whakapiri.He mea nui kia mahara ko te 1,3-dimethylurea e whakapataritari ana i te kiri me nga kanohi, na reira me whai waahi haumaru i te wa e whakahaere ana.
● Whakamahinga: Ka taea te whakamahi i te N,N′-Dimethylurea: Hei rauemi timata ki te whakahiato i te N,N′-dimethyl-6-amino uracil.I roto i te whakakotahitanga me te β-cyclodextrin derivatives, ki te hanga i nga ranunga rewa iti (LMM), ka taea te whakamahi hei whakarewa mo te hydroformylation me nga tauhohenga Tsuji-Trost. Biginelli condensation i raro i nga tikanga whakarewa-kore.
