2,4-Dinitrofluorobenzene(CAS#70-34-8)
| Iikhowudi zoMngcipheko | I-R22 – Iyingozi xa iginyiwe R33 – Ingozi yeziphumo ezongezelekayo I-R34 – Ibangela ukutsha I-R42/43 – Inokubangela uvakalelo ngokuphefumla kunye nokudibana nolusu. R40 – Ubungqina obuncinane besiphumo somhlaza I-R23/24/25 – Ityhefu ngokuphefumla, xa udibana nesikhumba naxa uginyiwe. I-R43 – Inokubangela uvakalelo ngokudibana nolusu I-R36/38 – Iyacaphukisa amehlo kunye nolusu. R36/37/38 – Ukucaphuka kwamehlo, inkqubo yokuphefumla kunye nolusu. |
| Inkcazelo yoKhuseleko | S22 – Musa ukuphefumla uthuli. S26 – Xa udibana namehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune iingcebiso zonyango. S36/37/39 – Nxiba iimpahla ezikhuselayo ezifanelekileyo, iiglavu kunye nokhuseleko lwamehlo/ubuso. S45 - Kwimeko yengozi okanye ukuba uziva ungaphilanga, funa iingcebiso zonyango ngokukhawuleza (bonisa ileyibhile nanini na kunokwenzeka.) S28A - S23 – Musa ukuphefumla umphunga. S7/9 - S36/37 – Nxiba iimpahla ezifanelekileyo zokukhusela kunye neeglavu. |

Intshayelelo
I-2,4-Dinitrofluorobenzene yikhompawundi ephilayo. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye neenkcukacha zokhuseleko:
Umgangatho:
- 2,4-Dinitrofluorobenzene yinto eqinileyo kunye neefomu ezingenambala ukuya kokukhanya kwekristale emthubi.
- Kwiqondo lokushisa legumbi, alinyibiliki emanzini, kodwa linyibilika kwi-solvents eziphilayo ezifana ne-ether kunye ne-dimethylformamide.
- Yikhompawundi enokutsha kwaye ifuna ukuphathwa ngononophelo.
Sebenzisa:
- 2,4-Dinitrofluorobenzene isetyenziswa ikakhulu ekwenzeni idayi emthubi kwiziqhushumbisi kunye namashishini epyrotechnic.
- Ikwasetyenziswa njengendawo ephakathi kwidayi kunye neepigments, kwaye inezicelo ezithile kuhlalutyo lweekhemikhali kunye ne-organic synthesis.
Indlela:
- 2,4-Dinitrofluorobenzene inokufunyanwa ngokufaka i-nitrification ye-p-chlorofluorobenzene.
- Indlela ethile yokulungiselela inokufezekiswa ngokuphendula kwe-nitric acid kunye ne-nitrate yesilivere, i-nitric acid egxininisiweyo kunye ne-thionyl fluoride, njl.
Ulwazi ngoKhuseleko:
- 2,4-Dinitrofluorobenzene yinto eyityhefu enokubakho nemingcipheko ye-carcinogenic kunye ne-teratogenic.
- Iiglavu ezikhuselayo, izibuko, kunye nempahla yokukhusela kufuneka zinxitywe ngexesha lokusebenza.
- Kulumkele ukudibana nolusu, amehlo, kunye nomgudu wokuphefumla.
- Inkunkuma kufuneka ilahlwe ngokuhambelana nemigaqo efanelekileyo yokusingqongileyo kwaye kufuneka ingakhutshelwa kwiindawo ezinamanzi okanye kwindawo engqongileyo.
