N,N-Diethylaniline CAS:91-66-7
Isingeniso somkhiqizo
N,N-Diethylaniline CAS:91-66-7
I-N,N-diethylaniline uketshezi olunamafutha aphuzi olukhanyayo olungasetshenziswa ukulungisa odayi be-azo, odayi be-triphenylmethane, njll. Kuphinde kube okuphakathi okubalulekile kokuhlanganiswa kwezidakamizwa nabathuthukisi befilimu enemibala, futhi ukusetshenziswa kwayo kubanzi kakhulu.
umzila wokwenziwa
Chaza i-dppe (1 mg, 0.0025 mmol) ku-nBu2O eyomile (1 mL) bese wengeza i-Karstedt catalyst (29 μL, 0.0025 mol) kushubhu le-Schlenk ngaphansi kwe-argon atmosphere. Ngemva kokunyakazisa ingxube imizuzu eyi-10, i-PhSiH3 (247 μL, 2.0 mmol) yengezwe. I-Aniline (45.6 μL, 0.5 mmol), i-n-hexadecane (50 μL) njengendinganiso yangaphakathi, kanye ne-CH3ChemicalbookCO2H (63 μL, 1.1 mmol) zengezwe ngokushesha, zase zinyakaziswa ekamelweni lokushisa amahora angu-18. Lapho sekuqediwe, ingxube ihlanjululwe nge-ethyl acetate (15 mL), icinywe ngokucophelela nge-NaOH enamanzi (3M solution; 5 mL), bese inyakaziswa ekamelweni lokushisa amahora angu-3. Ingxube ewumphumela yakhishwa nge-ethyl acetate (izikhathi ezintathu), futhi izingqimba eziphilayo ezihlanganisiwe zomiswa phezu kwe-anhydrous MgSO4. Isigaba sezinto eziphilayo sahlungwa, sagxiliswa, futhi sahlanzwa ngekholomu ye-silica gel chromatography (ingxube ye-n-hexane/ethyl acetate) ukuze kunikezwe i-N,N-diethylaniline.
Inkambu yohlelo lokusebenza
Ingasetshenziselwa ukulungisa odayi be-azo, odayi be-triphenylmethane, njll. Kubuye kube okuphakathi okubalulekile kokuhlanganiswa kwezidakamizwa nabathuthukisi befilimu yombala, futhi ukusetshenziswa kwayo kubanzi kakhulu.
