Taw qhia
Methyl m-trifluoromethylbenzoate. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm cov khoom sib xyaw no:
Cov Khoom Siv: M-trifluoromethylbenzoate methyl ester yog cov kua tsis muaj xim nrog cov ntxhiab tsw tsw. Cov compound yog insoluble nyob rau hauv dej ntawm chav tsev kub, tab sis soluble nyob rau hauv ib co organic solvents xws li ethanol thiab ether.
Nws tuaj yeem siv los ua ib qho ester lossis aryl compound hauv cov organic synthesis cov tshuaj tiv thaiv rau kev tsim cov tshuaj bonds.
Txoj kev npaj: Kev npaj ntawm methyl m-trifluoromethylbenzoate feem ntau tau los ntawm cov tshuaj tiv thaiv. Ib txoj hauv kev npaj ntau yog los ua rau m-trifluoromethylbenzoic acid thiab methanol nyob rau hauv acidic tej yam kev mob los tsim methyl m-trifluoromethylbenzoate.
Cov ntaub ntawv kev nyab xeeb: M-trifluoromethylbenzoate methyl ester yog cov organic compound nrog qee yam tshuaj lom. Thaum siv lossis ua haujlwm, yuav tsum tau saib xyuas kom ua raws li kev tswj hwm kev nyab xeeb, xws li hnav hnab looj tes tiv thaiv, tsom iav, thiab khaub ncaws tiv thaiv. Tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag, thiab nco ntsoov siv nyob rau hauv ib qho chaw zoo-ventilated. Tsis txhob nqus nws cov vapors lossis hmoov av. Nyob rau hauv rooj plaub ntawm kev sib chwv los yog nqus tau pa, ntxuav qhov chaw raug mob tam sim ntawd thiab nrhiav kev pab kho mob.
