Intshayelelo
I-1,3-Difluorobenzene yi-organic compound. Oku kulandelayo kukwaziswa okuneenkcukacha kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-1,3-difluorobenzene:
Umgangatho:
I-1,3-Difluorobenzene yi-organofluorine compound ene-chemical stability ephezulu. Ayinakutsha kodwa isabela nge-oxidizing agents ezinamandla. I-1,3-Difluorobenzene iyanyibilika kwizinyibilikisi eziqhelekileyo ze-organic ezifana ne-ethanol, i-ether kunye ne-chloroform, kwaye ayinyibiliki emanzini.
Sebenzisa:
I-1,3-difluorobenzene inexabiso elithile lesicelo kwi-organic synthesis. Ingasetyenziswa njenge-reagent yokuphendula kwi-organic synthesis, umzekelo njenge-fluorinating reagent ye-aromatics compounds. I-1,3-difluorobenzene ingasetyenziselwa ukuhlanganiswa kwezinto ze-fluorescent, ukulungiswa kwezixhobo ze-organic optoelectronic kunye nezinye iindawo.
Indlela:
I-1,3-Difluorobenzene inokulungiswa nge-fluorination ye-benzene. Iindlela zokulungiselela ezisetyenziswa ngokuqhelekileyo yihydrogen fluoride njenge-agent ethambisayo okanye ukusetyenziswa kwe-ferrous fluoride complexes kwi-fluorination reactions.
Ulwazi ngoKhuseleko:
La manyathelo okhuseleko alandelayo kufuneka athathwe xa usebenzisa i-1,3-difluorobenzene:
1.1,3-I-Difluorobenzene inetyhefu ethile, enokubangela ingozi xa idibana nolusu, ukuphefumla irhasi okanye ukungenwa ngengozi. Izixhobo ezifanelekileyo zokuzikhusela ezinje ngeeglavu, iimpahla zamehlo ezikhuselayo, kunye nemaski kufuneka zinxitywe ngexesha lokusetyenziswa.
2. Kulumkele ukudibana nee-oxidizing agents ezinamandla ukunqanda umlilo okanye ugqabhuko-dubulo.
3. Kufuneka igcinwe kwindawo eyomileyo, epholileyo kwaye engenamoya, kude nomlilo kunye nezinto ezinokutsha.
5. Kuphephe ukuxubana nezinye iikhemikhali kwaye uzigcine kude nabantwana kunye nabantu abangaziyo ukusebenza.
