Pentafluorophenol (CAS# 771-61-9)
| Iikhowudi zoMngcipheko | R36/37/38 – Ukucaphuka kwamehlo, inkqubo yokuphefumla kunye nolusu. I-R34 – Ibangela ukutsha I-R20/21/22 – Iyingozi ngokuphefumla, xa udibana nolusu naxa uginyiwe. I-R63 – Ingozi enokwenzeka yokwenzakala kumntwana ongekazalwa I-R43 – Inokubangela uvakalelo ngokudibana nolusu I-R23/24/25 – Ityhefu ngokuphefumla, xa udibana nesikhumba naxa uginyiwe. I-R45 – Isenokubangela umhlaza R67 – Umphunga unokubangela ukozela kunye nesiyezi R40 – Ubungqina obuncinane besiphumo somhlaza |
| Inkcazelo yoKhuseleko | S26 – Xa udibana namehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune iingcebiso zonyango. S36 – Nxiba iimpahla ezifanelekileyo ezikhuselayo. 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. S36/37 – Nxiba iimpahla ezifanelekileyo zokukhusela kunye neeglavu. S24/25-Kuphephe ukudibana nolusu namehlo. S23 – Musa ukuphefumla umphunga. S53 – Kuphephe ukuba sesichengeni – fumana imiyalelo eyodwa phambi kokusetyenziswa. |

Intshayelelo
I-Pentafluorophenol yi-organic compound. Inezi mpawu zilandelayo:
1. Imbonakalo: ikristale engenambala eqinileyo.
4. I-Solubility: i-soluble kwi-solvents ye-organic efana ne-ethanol, i-dimethylformamide, njl., i-soluble kancinane emanzini.
5. I-Pentafluorophenol yinto eqinile ye-asidi, i-corrosion kwaye iyacaphukisa.
Usetyenziso oluphambili lwepentafluorophenol lulandelayo:
1. I-Fungicide: I-Pentafluorophenol ingasetyenziselwa ukubulala iintsholongwane kunye nokuvala inzala, kwaye inempembelelo enamandla yokuthintela kwiibhaktheriya, ukungunda kunye neentsholongwane. Ngokuqhelekileyo isetyenziselwa ucoceko lokubulala iintsholongwane kwizicelo zonyango, elebhu kunye nezoshishino.
3. I-Chemical reagents: i-pentafluorophenol ingasetyenziselwa njenge-reagents kunye ne-reagent intermediates kwi-organic synthesis.
I-Pentafluorophenol inokuveliswa ngokuphendula kwe-pentafluorobenzene kunye ne-alkaline oxidant efana ne-sodium peroxide. Inxaki yokusabela ethile yile:
C6F5Cl + NaOH + H2O2 → C6F5OH + NaCl + H2O
Ulwazi lokhuseleko lwepentafluorophenol lulandelayo:
1. Ulusu kunye nolusu lwamehlo: I-Pentafluorophenol inomsindo onamandla, kwaye ukudibanisa nolusu okanye amehlo kuya kubangela intlungu, ubomvu kunye nokuvuvukala kunye nezinye iimpawu ezingathandekiyo.
2. Iingozi zokuphefumla: Umphunga wepentafluorophenol unempembelelo ecaphukisayo kwindlela yokuphefumla, kwaye ukuphefumla kakhulu kunokubangela iimpawu ezinjengokhohlokhohlo kunye nobunzima bokuphefumla.
3. Iingozi zokungeniswa: I-Pentafluorophenol ithathwa njengetyhefu, kwaye ukugqithiswa ngokugqithisileyo kunokukhokelela ekuphenduleni okuyityhefu.
Xa usebenzisa i-pentafluorophenol, amanyathelo afanelekileyo okukhusela kufuneka athathwe, njengokugqoka iiglavu zokukhusela, izikhuselo zobuso, njl., kunye nokugcina indawo yokusebenza enomoya.
