Khoom npe:Aniline

Molecular hom:C6H7 N

CAS Nr:62-53-3

Cov khoom siv molecular:

Chemical Properties:

Aniline yog qhov yooj yim tshaj plaws thawj aromatic amine thiab ib tug compound tsim los ntawm kev hloov ntawm ib tug hydrogen atom nyob rau hauv lub benzene molecule nrog ib tug amino pawg. Nws yog cov roj tsis muaj xim zoo li cov kua nplaum uas muaj ntxhiab tsw muaj zog. Thaum rhuab mus rau 370 C, nws yog me ntsis soluble nyob rau hauv dej thiab soluble nyob rau hauv ethanol, ether, chloroform thiab lwm yam organic solvents. Nws ua xim av nyob rau hauv huab cua los yog nyob rau hauv lub hnub. Nws tuaj yeem distilled los ntawm chav. Ib qho me me ntawm zinc hmoov yog ntxiv los tiv thaiv oxidation thaum nws distilled. Lub purified aniline tuaj yeem ntxiv 10 ~ 15ppm NaBH4 los tiv thaiv oxidation deterioration. Kev daws ntawm aniline yog alkaline.
Nws yog ib qho yooj yim los tsim ntsev thaum nws reacts nrog acid. Cov hydrogen atoms ntawm nws cov amino pawg tuaj yeem hloov tau los ntawm pawg alkyl lossis acyl los tsim cov qib thib ob lossis qib peb aniline thiab acyl aniline. Thaum hloov cov tshuaj tiv thaiv tshwm sim, cov khoom ntawm ortho thiab para hloov cov khoom yog tsim. Nws reacts nrog nitrite los tsim diazonium ntsev, uas yuav siv tau los tsim ib tug series ntawm benzene derivatives thiab azo tebchaw.

Daim ntawv thov:

Aniline yog ib qho tseem ceeb tshaj plaws hauv kev lag luam dyeing. Nws tuaj yeem siv hauv kev lag luam dyeing los tsim cov kua qaub xim xiav G, kua qaub nruab nrab BS, kua qaub daj daj, ncaj txiv kab ntxwv S, ncaj rosé, indigo xiav, disperse daj xim av, cationic rosé FG thiab reactive ci ntsa iab liab X-SB, thiab lwm yam. Nyob rau hauv cov organic pigments, nws yog siv los tsim golden liab, golden liab g, loj liab hmoov, phenocyanine liab, roj soluble dub, thiab lwm yam. Nws kuj yuav siv tau raws li ib tug raw khoom rau tshuaj sulfa tshuaj, thiab raws li ib tug intermediate nyob rau hauv zus tau tej cov txuj lom, plastics, varnishes, films, thiab lwm yam. Nws kuj yuav siv tau raws li ib tug stabilizer nyob rau hauv ib tug explosives, raws li ib tug explosives. Nws tseem tuaj yeem siv los tsim hydroquinone thiab 2-phenylindole.
Aniline yog ib qho tseem ceeb raw khoom rau kev tsim cov tshuaj tua kab.
