Daim ntawv ntawm N,N-dimethylaniline yog: tsis muaj xim rau daj daj lossis xim av daj oily kua, nrog rau ntxhiab tsw qab.

N, N-dimethylaniline (DMBA) muaj ntau yam kev siv, feem ntau suav nrog cov hauv qab no:

1. Cov tshuaj intermediates
DMBA yog ib qho tseem ceeb nruab nrab rau kev tsim cov vanillin, azo dyes, triphenylmethane dyes, thiab lwm yam.

2. Cov tshuaj yaj thiab cov tshuaj stabilizer
Nws kuj tseem siv tau ua cov kuab tshuaj thiab cov stabilizer, ua lub luag haujlwm hauv kev yaj thiab ruaj khov lwm yam tshuaj hauv kev tsim tshuaj.

3. Cov tshuaj reagents
DMBA kuj tseem siv tau ua ib qho tshuaj reagent analytical thiab muaj txiaj ntsig zoo rau kev tshuaj ntsuam tshuaj thiab kev sim.

Yuav tsum nco ntsoov tias txawm hais tias DMBA siv dav hauv kev lag luam tshuaj lom neeg, nws kuj suav hais tias yog carcinogen, yog li yuav tsum tau ceev faj tshwj xeeb thaum siv thiab khaws cia, thiab yuav tsum tau ua raws li cov cai kev nyab xeeb.

Cov khoom ntawm N, N-dimethylaniline feem ntau suav nrog cov hauv qab no:

1. Cov khoom siv lub cev
Zoo li: tsis muaj xim mus rau daj daj los yog xim av daj. Tsw: Nws muaj ntxhiab tsw qab.
Kev yaj: Nws yog soluble nyob rau hauv ntau yam organic solvents xws li ethanol, ether, chloroform, benzene, thiab me ntsis soluble nyob rau hauv dej.
Lub ntsiab lus kub thiab lub ntsiab lus yaj: Lub ntsiab lus kub yog li 193.1 ℃ txog 193.5 ℃, thiab lub ntsiab lus yaj yog qis dua, ntawm 1.5-2.5 ° C.

II. Cov khoom siv tshuaj lom neeg
Kev Kub Hnyiab: Cov tshuaj no kub hnyiab thiab yuav kub hnyiab thaum raug hluav taws qhib. Cov pa thiab cua tuaj yeem ua rau muaj kev sib xyaw ua ke.
Kev lom: Nws yog ib yam tshuaj lom heev uas tuaj yeem nqus tau los ntawm daim tawv nqaij thiab ua rau lom. Nws muaj kev lom zoo ib yam li aniline.
Kev Ruaj Ntseg: Nws yooj yim oxidized hauv huab cua lossis hauv lub hnub, ua rau xim tsaus dua.
Kev ua haujlwm: Nws tuaj yeem ua rau muaj ntau yam tshuaj lom neeg, xws li picric acid, alkyl halides, acylating agents, thiab lwm yam.

Cov khoom no yuav tsum tau saib xyuas tshwj xeeb rau kev nyab xeeb thaum lub sijhawm khaws cia, kev thauj mus los thiab kev siv N, N-dimethylaniline, thiab ua raws li cov txheej txheem ua haujlwm.
