    Te Whakamahinga Me te Hangahanga Dimethylurea

    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.
    Ngā Āhuatanga matū tioata ma
    Whakamahinga N,N'-Dimethylurea ka taea te whakamahi:

    • Hei rauemi timata ki te whakahiatoN,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.
    • Ki te whakahiatoN,N′-kua whakakorehia-4-aryl-3,4-dihydropyrimidinones na roto i te kondensation Biginelli i raro i nga tikanga whakarewa-kore.

     

    Whakamaramatanga ChEBI: He mema o te karaehe o te Urea ka whakakapihia e nga roopu methyl i nga waahi 1 me te 3.
    Whakaahuatanga Whanui Kiriata kore tae.
    Tauhohenga Hau me te Wai Wairewa wai.
    Kōtaha Tauhohenga Ko te 1,3-Dimethylurea he amide.Ka tauhohe nga Amides/imides ki nga pūhui azo me te diazo ki te whakaputa hau paitini.Ko nga hau mura ka hangaia e te tauhohenga o nga amides/imides pararopi me nga matū whakaheke kaha.He tino ngoikore nga Amides (he ngoikore ake i te wai).He iti ake te ahua o nga Imides, me te mea ka tauhohe me nga turanga pakari hei hanga tote.Arā, ka taea te urupare hei waikawa.Ko te whakaranu i nga amida me nga mea whakamaori penei i te P2O5, i te SOCl2 ranei ka whakaputa i te nitrile e rite ana.Ko te ngingiha o enei puhui ka whakaputa i nga waikura hauota (NOx).
    Pūmate Hauora TE WHAKAMAHI KAUPAPA: Ka whakamahana ki te pirau, ka tukuna e te 1,3-Dimethylurea he paowa paitini.
    Pūmate Ahi Ko nga raraunga tohu hiko mo te 1,3-Dimethylurea kaore i te waatea;Ko te 1,3-Dimethylurea pea ka mura.
    Kōtaha Haumaru He paitini na te ara intraperitoneal.Nga hua teratogenic me te whakawhanaunga.I korerohia nga raraunga whakarereke tangata.Ina whakamahana ki te pirau, ka puta he paowa paitini NOx
    Nga Tikanga Pure Whakapaia te Urea mai i te acetone/diethyl ether ma te whakamatao i roto i te pati hukapapa.Me tioata hoki mai i te EtOH ka whakamaroke ki te 50o/5mm mo te 24 haora [Bloemendahl & Somsen J Am Chem Soc 107 3426 1985].[Beilstein 4 IV 207.]
