Daim ntawv thov
1. 1,4-Difluorobenzene yog lub tsev thaiv tseem ceeb hauv kev tsim cov khoom xyaw tshuaj nquag thiab fluorinated intermediates rau kev tsim tshuaj.
2. 1 4-Difluorobenzene CAS 540-36-3 yog siv los tsim cov polymers tshwj xeeb uas muaj thermal stability siab rau kev siv tsheb thiab hluav taws xob thiab tsim cov khoom siv hluav taws xob ua haujlwm siab.
3. 1,4-Difluorobenzene ua haujlwm raws li tus qauv ntsuas hauv ib puag ncig (xws li, rau GC-MS txoj hauv kev) thiab ua cov kuab tshuaj hauv ntau yam kev tshuaj ntsuam xyuas.
Cia thiab ceev faj
1. Khaws 1,4-Difluorobenzene nyob rau hauv ib lub thawv kaw nruj nreem nyob rau hauv ib qho chaw txias, qhuav, zoo-ventilated, deb ntawm tshav kub, sparks, thiab qhib nplaim taws; Cov ntaub ntawv flammable cheeb tsam los yog tub yees ntawm 2-8℃yog pom zoo.
2. Khaws 1 4-Difluorobenzene CAS 540-36-3 nruj me ntsis sib cais los ntawm cov muaj zog oxidizing cov neeg ua hauj, raws li 1,4-Difluorobenzene yog incompatible, thiab xyuas kom meej cov ntim yog grounded los tiv thaiv electrostatic paug.
3. Kov 1,4-Difluorobenzene siv cov cuab yeej tiv thaiv tus kheej tsim nyog nrog rau cov hnab looj tes tiv thaiv tshuaj, tsom iav kev nyab xeeb, thiab hauv lub fume hood kom tsis txhob ua pa tawm.
Kev kub ceev teb rau cov dej xau
1. cais cov spill 1 4-Difluorobenzene CAS 540-36-3 cheeb tsam, tshem tawm tag nrho cov ignition qhov chaw, thiab muaj kua 1,4-Difluorobenzene siv qhuav inert absorbent cov ntaub ntawv xws li xuab zeb, tiv thaiv kev nkag mus rau hauv tej qhov chaw los yog dej.
2. Sau cov absorbed 1,4-Difluorobenzene siv cov cuab yeej tsis ua kom tsis muaj teeb meem rau hauv cov thawv ntim, cov ntawv lo rau pov tseg raws li cov khoom siv phom sij.
3. Kev tu neeg ua haujlwm 1,4-Difluorobenzene spills yuav tsum hnav cov khoom tiv thaiv tag nrho nrog rau cov cuab yeej ua pa ntawm tus kheej thiab xyuas kom muaj cua txaus thaum ntxuav.
Cov ntaub ntawv kev nyab xeeb
1. 1,4-Difluorobenzene yog cov kua thiab vapors heev heev (H224) nrog ib tug flash point ntawm 2 degree, thiab overexposure yuav ua rau kiv taub hau, xeev siab, narcosis, thiab ua pa tsis ua hauj lwm.
2. 1 4-Difluorobenzene CAS 540-36-3 muaj teeb meem yog tias nqos tau (H302), tshuaj lom yog nqus los ntawm daim tawv nqaij (H311), thiab muaj teeb meem yog tias nqus tau (H332); combustion tsim cov pa phem xws li carbon oxides thiab hydrogen fluoride.
3. 1,4-Difluorobenzene raug cais rau kev thauj mus los ua cov kua hluav taws xob (UN 1993, Hazard Class 3, Packing Group II) thiab yuav tsum tau ua raws li cov lus qhia ceev faj P210, P233, P240, thiab P280 .
