2-Cyano-5-fluorobenzotrifluoride (CAS # 194853-86-6) Taw qhia
4-fluoro-2-(trifluoromethyl) benzonitrile yog cov xim tsis muaj xim lossis cov khoom uas muaj cov ntxhiab tsw tsw qab. Nws muaj kev ruaj ntseg zoo thiab thermal stability ntawm chav tsev kub, thiab yog insoluble hauv dej, tab sis soluble nyob rau hauv ntau cov organic solvents.
Siv:
4-fluoro-2-(trifluoromethyl) benzonitril yog ib qho tseem ceeb ntawm cov organic nruab nrab uas tuaj yeem ua lub luag haujlwm tseem ceeb hauv kev tsim tshuaj, tshuaj tua kab thiab tshuaj tshwj xeeb. Nws tuaj yeem siv rau hauv kev sib xyaw ntawm cov tshuaj, fungicides, antioxidants thiab lwm yam sib xyaw, tab sis kuj tuaj yeem siv los ua cov xim pleev xim thiab cov ntaub ntawv softener.
Txoj kev:
Cov txheej txheem kev npaj 4-fluoro-2-(trifluoromethyl) benzonitrile yog ua tiav los ntawm fluorination cov tshuaj tiv thaiv thiab cyanation cov tshuaj tiv thaiv. Ib txoj hauv kev yog los ua 2,4-difluoro-1-chlorobenzene nrog trifluoronitrile los muab cov khoom.
Cov ntaub ntawv kev nyab xeeb:
Hnav cov hnab looj tes tiv thaiv tshuaj, tsom iav thiab khaub ncaws tiv thaiv thaum tuav 4-fluoro-2-(trifluoromethyl) benzonitril. Tsis txhob sib cuag nrog daim tawv nqaij thiab nqus pa ntawm vapors. Nyob rau hauv rooj plaub ntawm kev sib chwv, yaug tam sim ntawd nrog dej ntau thiab nrhiav kev pab kho mob. Thaum khaws cia, nws yuav tsum muab tso rau hauv qhov chaw qhuav, txias, qhov cua, kom deb ntawm hluav taws thiab oxidant. Ua raws li cov txheej txheem kev nyab xeeb thiab cov txheej txheem.
