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 feem ntau yog siv los ua cov tshuaj nruab nrab rau dyes, tshuaj, explosives, plastics, thiab photographic thiab roj hmab chemicals. Ntau cov tshuaj tuaj yeem tsim los ntawm Aniline, suav nrog:

Isocyanaates rau kev lag luam urethane

Antioxidants, activators, accelerators, thiab lwm yam tshuaj rau kev lag luam roj hmab

Indigo, acetoacetanilide, thiab lwm yam dyes thiab pigments rau ntau yam kev siv

Diphenylamine rau roj hmab, roj av, yas, ua liaj ua teb, tawg, thiab tshuaj industries

Ntau yam fungacides thiab herbicides rau kev lag luam ua liaj ua teb

Pharmaceutical, organic tshuaj, thiab lwm yam khoom
