2-methyl-3-nitrobenzotrifluoride (CAS# 6656-49-1)
| Iikhowudi zoMngcipheko | I-R20/21/22 – Iyingozi ngokuphefumla, xa udibana nolusu naxa uginyiwe. R36/37/38 – Ukucaphuka kwamehlo, inkqubo yokuphefumla kunye nolusu. I-R25 – Inetyhefu xa iginyiwe I-R36/38 – Iyacaphukisa amehlo kunye nolusu. R24/25 - |
| Inkcazelo yoKhuseleko | S23 – Musa ukuphefumla umphunga. S26 – Xa udibana namehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune iingcebiso zonyango. S36/37/39 – Nxiba iimpahla ezifanelekileyo zokukhusela, iiglavu kunye nokukhusela amehlo/ubuso. S60 – Esi sixhobo kunye nesingxobo saso kufuneka silahlwe njengenkunkuma eyingozi. S45 - Kwimeko yengozi okanye ukuba uziva ungaphilanga, funa iingcebiso zonyango ngokukhawuleza (bonisa ileyibhile nanini na kunokwenzeka.) S36/37 – Nxiba iimpahla ezifanelekileyo zokukhusela kunye neeglavu. S20 – Xa usebenzisa, ungatyi okanye usele. S36 – Nxiba iimpahla ezifanelekileyo ezikhuselayo. S28 – Emva kokudibana nolusu, hlamba ngoko nangoko ngeesepha ezininzi. |

Intshayelelo
I-2-methyl-3-nitrotrifluorotoluene yi-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, iindlela zokwenza kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: Ikristale emhlophe eqinileyo
-Ukunyibilika: Inyibilika kwizinyibilikisi eziphilayo ezifana ne-ether, i-methanol kunye ne-dimethyl sulfoxide
Sebenzisa:
- Isenokusetyenziswa njenge-reagent kwi-organic synthesis reactions, njengomthombo we-nitrous acid kunye ne-sulphur dioxide.
Indlela:
- I-MTF idla ngokulungiswa nge-nitrification kunye ne-fluorine endaweni ye-benzoic acid. Okokuqala, i-asidi ye-benzoic i-nitrified ukufumana i-2-nitrobenzoic acid, kwaye ke iqela le-carboxyl kwi-nitrobenzoic acid litshintshwa kwiqela le-trifluoromethyl ngokuphendula kwegesi ye-fluorine.
Ulwazi ngoKhuseleko:
- I-MTF inobuthi obuthile kwaye inokubangela ingozi kumzimba womntu, ngoko ke kuyimfuneko ukunikela ingqalelo kukhuseleko xa usebenzisa kwaye usebenza.
- Ukuqhagamshelana nolusu, ukuphefumla, okanye ukungenwa ngengozi kunokubangela ukucaphuka kunye nokulimala, kwaye kufuneka kuthathwe amanyathelo okhuseleko afanelekileyo ukuba kuyimfuneko.
- Kulumkele ukudibana nee-oxidizing agents ezinamandla kunye nezinto ezinokutsha ukuthintela umlilo okanye ugqabhuko-dubulo.
- Xa usebenzisa kwaye ugcina, landela iinkqubo ezifanelekileyo zokusebenza zokhuseleko.
