Umngcipheko kunye noKhuseleko
| Iikhowudi zoMngcipheko | I-R10-Inokutsha R36/37/38 – Ukucaphuka kwamehlo, inkqubo yokuphefumla kunye nolusu. I-R34 – Ibangela ukutsha I-R22 – Iyingozi xa iginyiwe |
| Inkcazelo yoKhuseleko | S26 – Xa udibana namehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune iingcebiso zonyango. S36/37 – Nxiba iimpahla ezifanelekileyo zokukhusela kunye neeglavu. S45 - Kwimeko yengozi okanye ukuba uziva ungaphilanga, funa iingcebiso zonyango ngokukhawuleza (bonisa ileyibhile nanini na kunokwenzeka.) S36/37/39 – Nxiba iimpahla ezifanelekileyo zokukhusela, iiglavu kunye nokukhusela amehlo/ubuso. S16 – Gcina kude kwimithombo yomlilo. |

Intshayelelo
N-trifluoroacetimidazole. Inezi mpawu zilandelayo:
1. Imbonakalo: I-N-trifluoroacetamidazole yinto eqinileyo yecrystalline engenambala.
2. I-Solubility: Inokuchithwa kwizinto ezininzi ze-organic solvents, ezifana ne-ethanol, i-ethyl acetate kunye ne-dimethylformamide, njl.
3. Ukuzinza: I-N-trifluoroacetamidazole inozinzo oluhle ekushiseni nasekukhanyeni.
I-N-trifluoroacetimidazole isetyenziswa kakhulu kwintsimi ye-organic synthesis kwaye isoloko isetyenziswa njenge-hydrofluorate formation reagent ye-organic compounds. Ingasetyenziselwa ukuvelisa iikhompawundi ezahlukeneyo eziqulethe amaqela e-trifluoroacetyl, afana neeketones kunye ne-alcohol, i-enol ethers kunye ne-esters.
Iindlela zokulungiselela i-N-trifluoroacetamidazole ikakhulu zezi zilandelayo:
1. I-Chlorinate trifluoroacetic acid okanye i-sodium fluoride iphendulwa kunye nemidazole ukufumana imveliso ekujoliswe kuyo.
2. I-Trifluoroacetic anhydride iphendulwa kunye ne-imidazole phantsi kweemeko ze-acidic ukuvelisa i-N-trifluoroacetylimidazole.
1. Nxiba iiglavu ezifanelekileyo zokukhusela, iiglasi zokukhusela kunye nempahla yokukhusela xa usebenzisa.
2. Gwema ukuphefumlela uthuli okanye umphunga kwaye uqinisekise ukuba indawo yokusebenza ingena kakuhle.
3. Kuphephe ukudibana nesikhumba kunye namehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune unyango.
4. Gcina kude kwimithombo yomlilo kunye nee-oxidants kwaye uzigcine zivaliwe xa uzigcina.
