Gukoresha Dimethylurea Na Synthesis

Ibisobanuro	1, 3-Dimethylurea ni inkomoko ya urea kandi ikoreshwa nkigihe gito muri synthesis.Nifu ya kirisiti itagira ibara ifite uburozi buke.Ikoreshwa kandi muri synthesis ya cafeyine, imiti yimiti, imiti yimyenda, imiti yica ibyatsi nibindi.Mu nganda zitunganya imyenda 1,3-dimethylurea ikoreshwa nkigihe gito kugirango habeho umusaruro wa fordehide-yubusa-byoroshye-kurangiza ibikoresho byimyenda.Mu gitabo cy’ibicuruzwa by’Ubusuwisi hari ibicuruzwa 38 birimo 1,3-dimethylurea, muri byo ibicuruzwa 17 bigenewe gukoresha abaguzi.Ubwoko bwibicuruzwa ni urugero amarangi nibikoresho byoza.Ibiri muri 1,3-dimethylurea mubicuruzwa byabaguzi bigera kuri 10% (Igitabo cyibicuruzwa byo mu Busuwisi, 2003).Gukoresha kwisiga byasabwe, ariko nta makuru ahari nkayakoreshwa nyayo muri porogaramu.
Ibikoresho bya Shimi	kristu yera
Gukoresha	N,N′ -Dimethylurea irashobora gukoreshwa: Nkibikoresho byo gutangira gushushanyaN,N′ -Dimethyl-6-amino uracil. Hamwe na β-cyclodextrin ikomoka, kugirango ikore imvange nkeya (LMMs), ishobora gukoreshwa nkumuti wa hydroformylation hamwe na Tsuji-Trost. GuhinduraN,N′ -Yasubiwemo-4-aryl-3,4-dihydropyrimidinone ikoresheje kondegene ya Biginelli mubihe bidafite imbaraga.
Ibisobanuro	ChEBI: Umunyamuryango wicyiciro cya ureas ni urea isimburwa nitsinda rya methyl kumwanya wa 1 na 3.
Ibisobanuro rusange	Kirisiti itagira ibara.
Umwuka & Amazi	Amazi ashonga.
Umwirondoro wa reaction	1,3-Dimethylurea ni amide.Amide / imide yitwara hamwe na azo hamwe na diazo kugirango bibyare imyuka yubumara.Imyuka yaka ikorwa nigikorwa cya amide / imide hamwe ningingo zigabanya imbaraga.Amide nintege nke cyane (intege nke kuruta amazi).Imide ntabwo ari shingiro nyamara kandi mubyukuri reaction hamwe nifatizo zikomeye zo gukora umunyu.Ni ukuvuga, barashobora kwitwara nka acide.Kuvanga amide hamwe ningingo zangiza nka P2O5 cyangwa SOCl2 bibyara nitrile ihuye.Gutwika kw'ibi bikoresho bitanga okiside ivanze ya azote (NOx).
Ubuzima	ACUTE / CHRONIC HAZARDS: Iyo ashyutswe kubora 1,3-Dimethylurea isohora imyotsi yuburozi.
Fire Hazard	Flash point ya data ya 1,3-Dimethylurea ntabwo iboneka;1,3-Dimethylurea birashoboka ko ishobora gutwikwa.
Umwirondoro wumutekano	Muburyo bwuburozi muburyo bwa intraperitoneal.Ingaruka za teratogenic ningaruka zimyororokere.Amakuru yimiterere yabantu yatangajwe.Iyo ishyutswe kugirango ibore isohora imyotsi yuburozi ya NOx
Uburyo bwo kweza	Crystallize urea kuva acetone / diethyl ether ukonje mubwogero bwa barafu.Kandi koresha kristu muri EtOH hanyuma uyumishe kuri 50o / 5mm kumasaha 24 [Bloemendahl & Somsen J Am Chem Soc 107 3426 1985].[Beilstein 4 IV 207.]
