4-trifluoromethylanilineyog ib qho tshuaj organic nrog cov tshuaj formula ntawm c7h6nf3. Nws yog cov kua tsis muaj xim, insoluble hauv dej thiab soluble hauv cov kuab tshuaj organic. Nws yog ib qho tseem ceeb nruab nrab ntawm cov tshuaj thiab tshuaj tua kab, thiab tuaj yeem siv los npaj cov tshuaj tua kab xws li cyhalothrin, fipronil, thiab fluorouracil. Siv thiab khaws cia raws li cov lus qhia tshwj xeeb, tsis muaj kev puas tsuaj, thiab tsis txhob sib cuag nrog oxides. Cov khoom no decomposes rau hauv cov pa luam yeeb thaum rhuab. Poisoning tshwm sim los ntawm kev nqus, nqus ntawm daim tawv nqaij thiab digestive ib ntsuj av. Nws yuav tsum tau muab kaw thiab khaws cia rau hauv qhov cua thiab qhov chaw qhuav kom tsis txhob sib cuag nrog lwm cov oxides. Kev ntim khoom yuav tsum yog ua los ntawm cov khoom siv padding sab nraum lub khob iav thiab hauv lub thawv ntoo lossis lub thoob hlau. Khaws nyob rau hauv ib lub warehouse txias thiab ventilated. Khaws kom deb ntawm qhov hluav taws kub thiab cua sov thiab tsis txhob tshav ntuj ncaj qha; Khaws thiab thauj cais los ntawm cov khoom siv raw; Ua tib zoo saib xyuas kom tsis txhob muaj kev puas tsuaj rau lub thawv.
Tom qab chlorination ntawm p-trifluoromethylaniline, 2, 6-dichloro-p-amino trifluoromethyl toluene tuaj yeem tau. Nws yog ib qho tseem ceeb nruab nrab. Nws yog siv rau hauv kev lag luam tshuaj tua kab los ua kom muaj kev ua tau zoo thiab tsis muaj tshuaj lom cov tshuaj tua kab fipronil (Regent), cyhalothrin, fluorouracil, herbicides ibuprofen, ethyl chemicalbook butene flurane, thiab lwm yam. . Nrog rau kev txuas ntxiv tob zuj zus ntawm cov tshuaj ntsuab tshuaj ntsuab thiab kev tshawb fawb tshuaj tshiab, kev siv tshiab tau tsim tawm tsis tu ncua, thiab tau dhau los ua cov khoom lag luam tseem ceeb thiab pheej hmoo.
2, 6-dichloro-4-trifluoromethylaniline yog ib qho tseem ceeb ntawm cov tshuaj tua kab synthesis intermediate, uas feem ntau yog siv los ua ke fluorofenitrile thiab lwm yam tshuaj tua kab fluoro organic. Cov txheej txheem yog raws li nram no: ntxiv 200g p-trifluoromethylaniline thiab 480g dichloroethane rau hauv 3L reactor, tswj qhov kub thiab txias rau 10 degree, do thiab tso cov tshuaj tov nrog 503chemicalbookg sulfonyl chloride thiab 190g dichloroethane li ntawm 3h. Tom qab tso tseg, txuas ntxiv cov tshuaj tiv thaiv ntawm 50 degree rau 2h. Tom qab cov tshuaj tiv thaiv ua tiav, txo qhov kub thiab txias, ntxuav nrog dej, ntxuav nrog saturated sodium carbonate aqueous tov, tshem tawm cov ntsev inorganic, thiab mloog zoo rau cov organic theem kom tshem tawm cov hnyav, 144g ntawm 2,6-dichloro{{16. }}trifluoromethylaniline tau txais los ntawm kev kho.
P-nitrotoluene li raw khoom txoj kev: p-nitrotoluene yog brominated nrog bromine los tsim p-dibromomethyl nitrobenzene, ces brominated nrog sodium hypobromate los tsim p-tribromomethyl nitrobenzene, ces fluorinated nrog antimony trifluoride, thiab ces txo nrog tin dichloride kom tau p- trifluoromethyl phenylamine. Txoj kev no yog ib txoj kev classic. Cov khoom siv raw siv tau yooj yim, tab sis bromination yuav tsum tau bromine ntau dua, thiab nws tsuas yog hloov pauv nruab nrab xwb. Nws kuj yuav tsum tau fluorinated nrog sbf3 thiab txo nrog SnCl2. Cov txheej txheem yog complex thiab muaj ntau peb pov tseg, uas yog nyuaj rau industrialize. Yog tias bromination tuaj yeem hloov tau los ntawm chlorination, fluorination nrog HF thiab txo qis los ntawm cov qauv kev txo qis, nws yuav muaj qee qhov tseem ceeb hauv kev lag luam.
P-chlorotrifluoromethylbenzene raws li cov khoom siv raw: p-chlorotrifluoromethylbenzene reacts nrog ammonia nyob rau hauv lub siab thiab kub siab (150 ~ 240 degree) los tsim p-trifluoromethylaniline. Txawm hais tias p-chlorotrifluoromethylbenzene tau ua cov khoom lag luam, cov xwm txheej ntawm ammonolysis yog qhov hnyav, thiab kev lag luam nyuaj.
P-trichloromethylbenzene isocyanate raws li cov khoom siv raw: p-trichloromethylbenzene isocyanate reacts nrog hydrogen fluoride los ua p-trifluoromethylaniline hydrofluorate, thiab ces reacts nrog puag. Txoj kev no tau tsim tawm txawv teb chaws nyob rau xyoo tas los no, thiab p-trichloromethylbenzene isocyanate tuaj yeem siv p-methylaniline ua raw khoom, phosgene tuaj yeem tsim p-trichloromethylchloroformylaniline, thiab ntxiv rau p-trichloromethylbenzene isocyanate.
