| Iikhowudi zoMngcipheko | I-R45 – Isenokubangela umhlaza I-R23/24/25 – Ityhefu ngokuphefumla, xa udibana nesikhumba naxa uginyiwe. R48/22 – Ingozi eyingozi yomonakalo omkhulu empilweni ngokuba sesichengeni ixesha elide ukuba iginyiwe. R51/53 – Ityhefu kwizinto eziphila emanzini, inokubangela iziphumo ezibi zexesha elide kwindawo ehlala emanzini. I-R62 – Umngcipheko onokubakho wokuphazamiseka kokuchuma R68 – Umngcipheko onokubakho weziphumo ezingajikiyo R39/23/24/25 - I-R11 – Iyatsha kakhulu R52/53 – Iyingozi kwizinto eziphila emanzini, inokubangela iziphumo ezibi zexesha elide kwindawo ehlala emanzini. I-R36 – Iyandicaphukisa emehlweni I-R20/21/22 – Iyingozi ngokuphefumla, xa udibana nolusu naxa uginyiwe. R50/53 – Ityhefu kakhulu kwizinto eziphila emanzini, inokubangela iziphumo ezibi zexesha elide kwindawo ehlala emanzini. |
| Inkcazelo yoKhuseleko | S53 – Kuphephe ukuba sesichengeni – fumana imiyalelo eyodwa phambi kokusetyenziswa. S45 - Kwimeko yengozi okanye ukuba uziva ungaphilanga, funa iingcebiso zonyango ngokukhawuleza (bonisa ileyibhile nanini na kunokwenzeka.) S61 –Kuphephe ukukhutshelwa kokusingqongileyo. Jonga kwimiyalelo ekhethekileyo / kumaphepha edatha yokhuseleko. S36/37 – Nxiba iimpahla ezifanelekileyo zokukhusela kunye neeglavu. S16 – Gcina kude kwimithombo yomlilo. S26 – Xa udibana namehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune iingcebiso zonyango. S60 – Esi sixhobo kunye nesingxobo saso kufuneka silahlwe njengenkunkuma eyingozi. |

Intshayelelo
I-2,4-Dinitrotoluene, eyaziwa ngokuba yi-DNMT, i-organic compound.
Umgangatho:
- Imbonakalo: Iikristale ezingenambala okanye iikristale ezimdaka-tyheli.
- Iqinile kwiqondo lokushisa, i-soluble kwii-solvents eziphilayo ezifana ne-ethanol kunye ne-methylene chloride, i-soluble emanzini.
- Iqhuma ngamandla kwaye inetyhefu ethile emzimbeni.
Sebenzisa:
- Njengemathiriyeli ekrwada yeziqhushumbisi zasemkhosini, ezinje ngokwenziwa kweziqhushumbisi kunye nepyrotechnics.
- Isetyenziswa njenge-pigment intermediates, njengokwenziwa kwedayi kunye nemathiriyeli ye-photosensitive.
-Izicelo kwi-organic synthesis reactions, ezifana nokulungiswa kweerejenti zelothe zezinye iikhompawundi.
Indlela:
I-2,4-i-Dinitrotoluene idla ngokulungiswa ngokuphendula kwe-toluene nge-nitric acid. Iindlela eziqhelekileyo ziquka indlela ye-nitric deboronic acid, indlela ye-nitrate ye-ferrous, kunye nendlela edibeneyo ye-asidi. Amanyathelo okhuseleko angqongqo ayafuneka ngexesha lamalungiselelo.
Ulwazi ngoKhuseleko:
I-2,4-Dinitrotoluene iqhuma kakhulu kwaye inokubangela imililo eyingozi kunye nokudubula.
- Izixhobo zokuzikhusela ezinje ngeglavu zokhuselo, iiglavu kunye neegawuni kufuneka zinxitywe xa uphethe okanye uphethe.
Kuphephe ukuphefumla iirhasi, umsi, uthuli, kunye nomphunga, kwaye uphephe ukudibana nolusu namehlo.
- Gcina kude nomlilo kunye nemithombo yobushushu ngexesha lokusetyenziswa.
