2,6-Dinitrotoluene(CAS#606-20-2)
| 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. R52/53 – Iyingozi 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 I-R36 – Iyandicaphukisa emehlweni I-R20/21/22 – Iyingozi ngokuphefumla, xa udibana nolusu naxa uginyiwe. |
| 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. S456 - S36/37 – Nxiba iimpahla ezifanelekileyo zokukhusela kunye neeglavu. S26 – Xa udibana namehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune iingcebiso zonyango. S16 – Gcina kude kwimithombo yomlilo. |

Intshayelelo
I-2,6-Dinitrotoluene, eyaziwa ngokuba yi-DNMT, i-organic compound. Sisiqina esingenambala, esiyikristale esiphantse singanyibiliki emanzini kwiqondo lobushushu begumbi kwaye sinyibilika kwizinyibilikisi eziphilayo ezifana ne-ether kunye ne-petroleum ether.
I-2,6-Dinitrotoluene isetyenziswa ikakhulu njengesithako kwiziqhushumbisi kunye neziqhushumbisi. Inomsebenzi ophezulu wokuqhushumba kunye nozinzo, kwaye isoloko isetyenziswa ekulungiseleleni iziqhushumbisi zasemkhosini nezomkhosi.
Indlela yokulungiselela i-2,6-dinitrotoluene ngokuqhelekileyo ifunyenwe nge-nitrification ye-toluene. Indlela ethile yokulungiselela ibandakanya i-dropwise toluene kumxube we-nitric acid kunye ne-asidi ye-sulfuric, kwaye ukusabela kuqhutyelwa phantsi kweemeko ezivuthayo.
Ngokuphathelele ukhuseleko, i-2,6-dinitrotoluene yinto enobungozi. Iyacaphukisa kakhulu kwaye i-carcinogenic, kwaye inokubangela ukucaphuka kunye nokungaguquguquki komzimba ukuba ifakwe ngaphakathi okanye idibene nolusu. Xa usebenza, kufuneka kuthathwe amanyathelo angqongqo okhuseleko, njengokugqoka iiglavu zokukhusela, iiglasi kunye nezixhobo zokuphefumla, kunye nokusebenza kwindawo engenamoya. Ukugcinwa kunye nokuphathwa kwe-2,6-dinitrotoluene kwakhona kufuneka ihambelane nemimiselo efanelekileyo kunye nemigangatho yokuqinisekisa ukhuseleko lomntu kunye nokhuseleko lokusingqongileyo.
