Txoj kev:
3-fluoro-4-nitrotoluene yog npaj nyob rau hauv ntau txoj kev, thiab ib tug classic txoj kev yog tau los ntawm fluorination ntawm cyannitrobenzene. Cov txheej txheem kev npaj tshwj xeeb yog qhov nyuaj thiab yuav tsum muaj qee yam kev sim tshuaj lom neeg thiab cov txheej txheem.
Cov ntaub ntawv kev nyab xeeb:
3-fluoro-4-nitrotoluene yog cov tshuaj lom neeg. Thaum lub sijhawm ua haujlwm, yuav tsum tau saib xyuas kom tsis txhob muaj kev sib cuag ntawm daim tawv nqaij thiab qhov muag, thiab ua kom muaj cua txaus. Yog nqus tau los yog nqus tau, nrhiav kev kho mob tam sim ntawd. Thaum lub sij hawm cia, kev sib cuag nrog cov combustibles, oxidants, thiab lwm yam yuav tsum tau zam, thiab muab cia rau hauv qhov chaw txias, qhuav. Nws yog ib qho tsim nyog yuav tsum ua raws li cov cai thiab cov kev cai uas cuam tshuam thiab tswj thiab pov tseg cov khoom pov tseg kom zoo. Thaum siv lossis tuav, thov xa mus rau thiab ua raws li cov txheej txheem kev nyab xeeb ua haujlwm.
