Taw qhia
Pentafluorophenol yog ib qho organic compound. Nws muaj cov khoom nram qab no:
1. Cov tsos: xim tsis muaj xim crystalline khoom.
4. Solubility: soluble nyob rau hauv organic solvents xws li ethanol, dimethylformamide, thiab lwm yam., me ntsis soluble nyob rau hauv dej.
5. Pentafluorophenol yog ib yam khoom muaj zog acidic, corrosive thiab irritating.
Kev siv tseem ceeb ntawm pentafluorophenol yog raws li hauv qab no:
1. Fungicide: Pentafluorophenol tuaj yeem siv rau kev tua kab mob thiab ua kom tsis muaj menyuam, thiab muaj zog tiv thaiv kab mob, fungi thiab kab mob. Nws yog feem ntau siv rau kev tu cev tua kab mob hauv kev kho mob, kuaj thiab kev siv tshuab.
3. Tshuaj reagents: pentafluorophenol tuaj yeem siv los ua reagents thiab reagent intermediates hauv organic synthesis.
Pentafluorophenol tuaj yeem tsim los ntawm cov tshuaj tiv thaiv ntawm pentafluorobenzene nrog alkaline oxidant xws li sodium peroxide. Qhov kev sib npaug tshwj xeeb yog:
C6F5OH + NaOH + H2O2 → C6F5OH + NaOH + H2O
Cov ntaub ntawv kev nyab xeeb ntawm pentafluorophenol yog raws li hauv qab no:
1. Cov tawv nqaij thiab qhov muag khaus: Pentafluorophenol muaj qhov khaus khaus, thiab kev sib cuag ntawm daim tawv nqaij lossis qhov muag yuav ua rau mob, liab thiab o thiab lwm yam tsos mob tsis xis nyob.
2. Kev phom sij ntawm kev nqus pa: Cov pa ntawm pentafluorophenol muaj qhov ua rau ua rau lub ntsws ua pa, thiab kev nqus pa ntau dhau tuaj yeem ua rau cov tsos mob xws li hnoos thiab ua pa nyuaj.
3. Kev phom sij: Pentafluorophenol raug suav hais tias yog tshuaj lom, thiab kev noj ntau dhau yuav ua rau muaj tshuaj lom.
Thaum siv pentafluorophenol, yuav tsum muaj kev tiv thaiv kom tsim nyog, xws li hnav hnab looj tes tiv thaiv, daim npog ntsej muag, thiab lwm yam, thiab tswj xyuas qhov chaw ua haujlwm zoo.
