Chaw tsim tshuaj paus zoo nqi Aniline CAS: 62-53-3
Aniline yog qhov yooj yim tshaj plaws aromomatic amine, benzene molecule hauv ib hydrogen atom rau cov neeg amino pawg ntawm cov lus teb tsim tawm, cov roj ua kua roj ua kua, muaj ntxhiab tsw muaj ntxhiab. Lub ntsiab lus melting yog -6.3 ℃, qhov cub npau npau yog 184 ℃, lub ntsej muag sib npaug yog 1.5863, lub khob hluav taws xob (qhib lub khob) yog 70 ℃, lub spontaneous combarition point yog 770 , Lub decomposition yog rhuab rau 370 ℃, me ntsis soluble hauv dej, yooj yim soluble hauv ethanol, chloroform thiab lwm yam tshuaj kuab tshuaj organic. Puv xim av nthuav tawm xim thaum uas raug huab cua lossis hnub ci. Muaj stob distillation, distillation ntxiv ib qho nyiaj me me los tiv thaiv oxidation. 10 ~ 15 UPPM Nabh4 tuaj yeem raug ntxiv rau lub aniline kom tiv thaiv oxidation detioration. Kev daws kev tsis muaj kev daws teeb meem yog qhov yooj yim, thiab acid yog yooj yim los ua ntsev. Lub hydrogen atom ntawm nws cov pab pawg amino tuaj yeem hloov los ntawm cov pab pawg hydrocarbon lossis acyl pab los ua cov txheej txheem theem nrab lossis tertiary anilines thiab acyl anlilines. Thaum tus hloov pauv hloov tau yog nqa tawm, qhov sib txawv thiab cov khoom lag luam para-hloov pauv feem ntau yog tsim. Cov tshuaj tiv thaiv nrog nitrite yields dmzo ntsev los ntawm uas ib series ntawm benzene derivatives thiab azo cov tebchaw yuav ua tau.
