Intshayelelo
I-O-difluorobenzene yi-organic compound. Oku kulandelayo kukwazisa ngeepropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-o-difluorobenzene:
Umgangatho:
- Imbonakalo: I-O-difluorobenzene lulwelo olungenambala okanye ikristale emhlophe.
- Ukunyibilika: I-O-difluorobenzene iyanyibilika kwizinyibilikisi zendalo ezifana neealkoholi, ii-ethers kunye nebenzene.
Sebenzisa:
- I-O-difluorobenzene ingasetyenziselwa njengento yokuqala kunye nephakathi kwi-organic synthesis, kwaye isetyenziswe ngokubanzi kwimichiza, i-pesticide kunye nedayi.
- Isenokusetyenziswa njenge-additives kwi-coatings, i-solvents kunye ne-lubricant.
- I-O-difluorobenzene ingasetyenziswa kushishino lombane, umz. njengenxalenye yemathiriyeli yekristale elulwelo.
Indlela:
- Kukho iindlela ezimbini eziphambili zokulungiswa kwe-o-difluorobenzene: ukusabela kwe-fluorine compounds kunye ne-benzene kunye ne-fluorination reaction reaction ye-fluorinated benzene.
- Ukusabela kwe-fluorine compounds kunye ne-benzene kuxhaphakile, kwaye i-o-difluorobenzene inokufumaneka nge-fluorination ye-chlorobenzene ngegesi ye-fluorine.
- I-fluorination ekhethiweyo ye-benzene ene-fluorinated ifuna ukusetyenziswa kwe-fluorinating reagents ekhethiweyo ukwenzela ukuhlanganiswa.
Ulwazi ngoKhuseleko:
- Ukuvezwa kwi-o-difluorobenzene kunokubangela ukucaphuka kwesikhumba, amehlo kunye nenkqubo yokuphefumla, kwaye kufuneka kuthathwe amanyathelo okhuseleko.
- Nxiba iiglasi ezikhuselayo, iiglavu kunye nempahla yokusebenza xa usebenzisa i-o-difluorobenzene, kwaye ugcine indawo engenamoya.
- Zigcine kude nomlilo namaqondo obushushu aphezulu, kwaye uwagcine kwindawo epholileyo neyomileyo.
- Phambi kokuba usebenzise okanye uphathe i-o-difluorobenzene, funda kwaye ulandele izikhokelo zokuphatha ezifanelekileyo zokhuseleko.
