Chofunika
Maphunziro a Mankhwala:Nitrogen Mafuta -> Urea Coments
Kumwetulira kwa Canonan:Cn (c) c (= o) n
Gwiritsani Ntchito:1,1-Dimethylurea (N,N-dimethylurea) has been used in the Dowex-50W ion exchange resin-promoted synthesis of N,N′-disubstituted-4-aryl-3,4-dihydropyrimidinones.
Mawu owonjezera
1,1-dimethylureandi mankhwala ophatikizira ndi mawonekedwe a c3h8N2o. Amadziwikanso kuti Dimethylurea kapena DMU. Ndi ufa woyera wa kristoline, kusungunuka mosavuta m'madzi ndi okhazikika.
1,1-dimethylurea ali ndi ntchito zosiyanasiyana m'makampani osiyanasiyana. Chimodzi mwazomwe zimagwiritsidwa ntchito kwambiri ndi monga kutsuka mu kapangidwe kake. Nthawi zambiri imagwiritsidwa ntchito ngati gwero la Dimethylamine, nyumba yofunika yomanga popanga mankhwala opangira mankhwala, utoto ndi mankhwala ena.
M'makampani opanga mankhwala, 1,1-dimethylurea amagwiritsidwa ntchito ngati chotsogola cha kapangidwe ka mankhwala osokoneza bongo ndi mankhwala apakatikati.
Itha kugwiritsidwa ntchito ngati wothandizira mankhwala ogwirira ntchito zamankhwala ogwirira ntchito nthawi yayitali omwe amakhala. Amagwiritsidwanso ntchito ngati chothandizira pazomwe zimachitika.
Kuphatikiza apo, 1,1-dimethylurea imagwiritsidwanso ntchito mu kapangidwe ka herbicides ndi fungicides. Imagwira ngati chokhazikika ndikuwonjezera magwiridwe antchito awa agrochemicals. Ndikofunikira kwambiri kuti mugwire 1,1-dimethylurea ndi chisamaliro chifukwa imawonedwa ngati ikuwononga kapena kulumikizana ndi khungu kapena maso. Kusamala koyenera kuyenera kumwedwa mukamagwira ntchito ndi mankhwalawa, monga kuvala zida zoteteza ndikuonetsetsa mpweya wabwino.
Mwachidule, 1,1-dimethylurea ndi mafuta ambiri omwe angagwiritsidwe ntchito mu synthesis, mankhwala ogulitsa, ndi abulamumini. Katundu wake amapangitsa kuti ikhale yothandiza ngati yoteteza, komanso yothandizira mu njira zosiyanasiyana zamankhwala.
Karata yanchito
1,1-Dimethylurea, omwe amadziwikanso kuti DEU, ali ndi ntchito zingapo zofunika m'mafakitale osiyanasiyana. Nazi kugwiritsa ntchito zina:
Makampani opanga mankhwala:DMU imagwiritsidwa ntchito ngati gawo lapakatikati pa kaphatikizidwe wa mankhwala. Itha kuchitapo kanthu pakupanga mankhwala osokoneza bongo monga antiprine, phenobarbital, ndi theophylline. Kapangidwe kapadera kwa DMU kumapangitsa kuti ikhale ngati chipika chomanga kuti chipangidwe cha mamolekyulu achilengedwe.
Scantic Synthesis:DMU imagwiritsidwa ntchito kwambiri mu kapangidwe kake ngati reagent kapena zosungunulira. Itha kutenga nawo mbali pamachitidwe osiyanasiyana a mankhwala monga kuphatikizira, masiadation, ndi alkylation. Kutengeka kwa DMU ndi kukhazikika kumapangitsa kuti ikhale yoyenera pazosintha zosiyanasiyana kupanga zinthu zachilengedwe zachilengedwe.
Makampani A Dysteuff:DEMU imagwiritsidwa ntchito ngati chogwira ntchito yopanga utoto ndi utoto wina. Kapangidwe kake kamathandiza kutenga nawo mbali pazomwe zimapangitsa kuti ipangidwe ndi mitundu yolimba. Mamolekyulu a utoto opangidwa pogwiritsa ntchito DMU akhoza kugwiritsidwa ntchito m'matumba, kusindikiza mainki, ndi mapulogalamu ena aumudzi.
Makampani a Polymer:DMU imayenera kugwiritsa ntchito ma polima ndikupanga. Itha kugwiritsidwa ntchito ngati wothandizira wolumikizirana kapena gawo limodzi mu kapangidwe ka poureurethane ndi epoxy amatulukira. Ukadaulo uwu umapeza zopindulitsa, zomata, ndi mafakitale ena osiyanasiyana.
Makampani feteleza:DMU imatha kugwiritsidwa ntchito popanga feteleza woleredwa pang'onopang'ono. Malo ake ovomerezeka amalola kutulutsa kwa nayitrogeni, kupereka mbewu zokhala ndi michere yambiri nthawi yayitali.
Ndikofunikira kudziwa kuti mukamagwira ntchito ndi DMU kapena mankhwala aliwonse, mosamala chitetezo ndi madongosolo ayenera kutsatira chitetezo cha anthu ndi chilengedwe.
