Taw qhia
Trifluoromethoxyphenol. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
Cov tsos mob: Trifluoromethoxyphenol yog cov xim tsis muaj xim rau daj ntseg daj.
Solubility: Nws yog soluble hauv cov kuab tshuaj organic xws li ethanol, dimethylformamide, thiab methylene chloride, tab sis muaj tsawg solubility hauv dej.
Acidity thiab alkalinity: Trifluoromethoxyphenol yog cov kua qaub tsis muaj zog uas tuaj yeem cuam tshuam nrog alkalis.
Siv:
Chemical synthesis: trifluoromethoxyphenol feem ntau yog siv rau hauv cov organic synthesis cov tshuaj tiv thaiv thiab tuaj yeem siv los ua ib qho tseem ceeb hauv nruab nrab lossis reagent.
Txoj kev:
Trifluoromethoxyphenol tuaj yeem tau txais los ntawm kev ua haujlwm p-trifluoromethylphenol nrog methyl bromide. Trifluoromethoxyphenol tuaj yeem tau los ntawm kev sib cais trifluoromethylphenol nyob rau hauv ib qho dispersant thiab ntxiv methyl bromide, thiab tom qab cov tshuaj tiv thaiv, nws dhau los ua ib qho kev ua kom huv huv.
Cov ntaub ntawv kev nyab xeeb:
Trifluoromethoxyphenol yog khaus khaus thiab yuav tsum tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag.
Thaum siv lossis npaj, yuav tsum tau saib xyuas kev tiv thaiv, xws li hnav hnab looj tes tiv thaiv, looj tsom iav dub, thiab khaub ncaws tiv thaiv.
Thaum tuav lossis khaws cia, kev sib cuag nrog cov khoom xws li oxidants, acids, thiab alkalis yuav tsum zam kom tsis txhob muaj kev phom sij txaus ntshai.
Thov khaws trifluoromethoxyphenol kom zoo, kom deb ntawm hluav taws thiab kub kub, kom tsis txhob muaj kev sib tsoo lossis tawg.
Yog tias muaj kev tsis xis nyob lossis kev sib tsoo, thov nrog tus kws tshaj lij hauv lub sijhawm thiab ua haujlwm nrog nws raws li cov txheej txheem kev nyab xeeb uas cuam tshuam.
