N,N-diethylaniline muaj ntau yam kev siv:

Kev tsim cov xim: Feem ntau yog siv los tsim cov xim azo thiab cov xim triphenylmethane, thiab tuaj yeem npaj ntau yam xim xws li xim ntsuab ci ntsa iab, xim ntshav yooj yim, xim xiav acidic V, thiab lwm yam.
Tshuaj thiab tshuaj tua kab: Ua ib qho nruab nrab hauv kev lag luam tshuaj thiab tus tsim xim zaj duab xis, nws muaj ntau yam kev siv.
Kev Tshuaj Xyuas Tshuaj: Nws tuaj yeem siv los ua cov tshuaj reagent los nrhiav cov hlau xws li zinc thiab manganese.
Kev kho epoxy resin: Ua lub luag haujlwm txhawb nqa thiab catalytic hauv epoxy resin curing system, pab qhib pawg epoxy thiab ua rau epoxy resin dhau los ua qhov electrophilic ntxiv reaction.
Lwm yam kev siv: Hauv kev tsim khoom tiag tiag, N, N-diethylaniline kuj tseem siv dav ua tus neeg sawv cev khi kua qaub hauv cov tshuaj acylation.
N,N-diethylaniline yog ib qho tseem ceeb organic compound uas siv dav hauv ntau qhov chaw thiab muab kev txhawb nqa tseem ceeb rau kev txhim kho cov lag luam cuam tshuam.

Muaj ntau txoj hauv kev los ua N,N-diethylaniline. Cov hauv qab no yog peb txoj hauv kev tseem ceeb los ua cov khoom no:

Txoj Kev 1:

Cov khoom siv raw: dppe, nBu2O, Karstedt catalyst, PhSiH3, aniline, n-hexadecane, CH3CO2H.
Kauj Ruam: Yaj dppe rau hauv nBu2O qhuav, ntxiv cov tshuaj catalyst, do thiab tom qab ntawd ntxiv lwm cov khoom siv raw, do ntawm chav sov rau 18 teev. Tom qab ua tiav, nws tau diluted nrog ethyl acetate, do rau 3 teev, thiab thaum kawg purified los ntawm silica gel column chromatography kom tau txais cov khoom.
Txoj Kev 2:

Cov khoom siv raw: sodium bis-(trimethylsilyl) amide, triethylamine, bromobenzene.
Kauj Ruam: Sib tov cov khoom xyaw, ua kom sov rau qhov kub npau, thiab ua kom npau rau 8 teev thaum do. Tom qab distillation tawm cov kuab tshuaj, cov seem raug distilled hauv qab lub zog txo qis kom tau txais cov khoom.
​
Txhua txoj kev no muaj nws tus yam ntxwv, thiab cov kev tsim nyog tuaj yeem xaiv tau raws li cov kev xav tau thiab cov xwm txheej tshwj xeeb
