Taw qhia
M-trifluoromethoxyphenol. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
M-trifluoromethoxyphenol yog dawb crystalline khoom uas yog soluble nyob rau hauv organic solvents xws li ethers thiab cawv, tab sis insoluble nyob rau hauv dej. Nws yog acidic heev thiab oxidizing.
Kev Siv: Nws kuj tuaj yeem siv los ua ib qho ntxiv hauv cov tshuaj tua kab mob antioxidants, nplaim hluav taws, thiab photoinitiators, thiab lwm yam.
Txoj kev:
M-trifluoromethoxyphenol tuaj yeem npaj los ntawm trifluoromethylation ntawm cresol. Cov kauj ruam tshwj xeeb yog los ua cresol nrog trifluoromethane (fluorinating tus neeg sawv cev) nyob rau hauv lub xub ntiag ntawm ib tug reactive neeg sawv cev los tsim m-trifluoromethoxyphenol.
Cov ntaub ntawv kev nyab xeeb:
M-trifluoromethoxyphenol tsis ua rau muaj teeb meem loj rau tib neeg lub cev raws li kev siv ib txwm siv. Nws yog ib qho tshuaj thiab yuav tsum tau saib xyuas kom tsis txhob nqus cov plua plav lossis tawv nqaij. Cov cuab yeej tiv thaiv tus kheej tsim nyog xws li hnab looj tes tiv thaiv thiab tsom iav yuav tsum hnav thaum siv. Thaum khaws cia thiab tuav, yuav tsum tau saib xyuas kev nyab xeeb thiab kev tswj hwm kev nyab xeeb, kev sib cuag nrog cov khoom siv hluav taws xob yuav tsum raug zam, thiab kev sib xyaw nrog cov tshuaj xws li oxidants thiab acids muaj zog yuav tsum zam. Thaum muaj xwm txheej xws li xau, kev ntsuas kub tsim nyog yuav tsum tau coj los daws nws thiab tus kws tshaj lij yuav tsum tau sab laj.
