N,N-dimethylaniline yog nyob rau hauv daim ntawv ntawm cov kua roj daj daj. Cov hauv qab no yog cov lus piav qhia ntxaws ntxaws ntawm daim ntawv ntawm N,N-dimethylaniline:

Tsos: Xim av daj rau xim av oily kua nrog ib tug pungent tsw, thiab yooj yim oxidized kom tsaus xim.
Cov khoom siv lub cev: Tsis yaj hauv dej, tab sis yaj hauv cov kuab tshuaj organic xws li ethanol, ether, thiab chloroform. Nws lub ntsiab lus kub yog 193.5 ± 0.0 ° C, lub ntsiab lus yaj yog 1.5-2.5 ° C, thiab qhov ceev yog li 1.0 ± 0.1 g / cm3.
Hauv kev xaus, N,N-dimethylaniline tshwm sim ua kua roj daj daj ntawm chav tsev kub thiab siab, thiab muaj qee yam khoom siv lub cev thiab tshuaj lom neeg.

N,N-Dimethylaniline (DMBA) yog ib qho organic compound uas feem ntau yog siv ua xim nruab nrab thiab muaj ntau yam kev siv hauv kev lag luam. Cov hauv qab no yog cov kev siv tseem ceeb ntawm N,N-dimethylaniline:

Cov xim nruab nrab: Siv los ua vanillin, azo dyes, triphenylmethane dyes, thiab lwm yam.
Cov kuab tshuaj thiab cov stabilizers: Vim nws cov khoom siv tshuaj lom neeg tshwj xeeb, N, N-dimethylaniline tuaj yeem siv los ua cov kuab tshuaj thiab cov stabilizer.
Cov tshuaj reagents: Hauv kev tshuaj ntsuam tshuaj, N, N-dimethylaniline kuj tseem siv tau ua cov tshuaj reagent.
Lwm yam kev siv: Ntxiv rau cov kev siv tseem ceeb saum toj no, N, N-dimethylaniline kuj tseem siv tau rau lwm yam kev lag luam raws li qhov xav tau tshwj xeeb.
Yuav tsum nco ntsoov tias N,N-dimethylaniline yog ib yam tshuaj lom thiab muaj peev xwm ua rau mob qog noj ntshav, yog li nws yog ib qho tsim nyog yuav tsum ua raws li cov cai tswjfwm thaum lub sijhawm siv thiab khaws cia kom ntseeg tau tias cov neeg ua haujlwm muaj kev nyab xeeb thiab kev tiv thaiv ib puag ncig. Tib lub sijhawm, vim nws tawg, kev ntim khoom, kev khaws cia thiab kev thauj mus los kuj xav tau kev saib xyuas tshwj xeeb.
