-Zoo: Dawb crystalline khoom
- Melting point: 148-150 ° C
-Solubility: Soluble nyob rau hauv cov organic solvents, insoluble nyob rau hauv dej
Siv:
-Trifluoromethylthiobenzoic acid yog dav siv nyob rau hauv cov organic synthesis. Ib qho kev siv feem ntau yog ua ib qho khoom nruab nrab rau Txoj Kev Kawm ntawm ligands rau kev npaj cov hlau complexes nrog cov khoom tshwj xeeb.
-Nws kuj yog siv los ua ib qho nruab nrab hauv kev lag luam tshuaj thiab tshuaj tua kab, thiab koom nrog ntau yam kev cuam tshuam ntawm cov organic synthesis.
Txoj kev:
-Trifluoromethylthio benzoic acid tuaj yeem tau los ntawm kev ua haujlwm benzoic acid nrog trifluoromethanethiol. Cov tshuaj tiv thaiv feem ntau yog nqa tawm nyob rau hauv acidic tej yam kev mob, thiab kev nce qib ntawm cov tshuaj tiv thaiv yog txhawb los ntawm cua sov.
Cov ntaub ntawv kev nyab xeeb:
-Trifluoromethylthiobenzoic acid ua rau khaus ntawm daim tawv nqaij thiab qhov muag, yog li ua tib zoo saib xyuas kom tsis txhob muaj kev sib cuag ncaj qha thaum siv nws.
- Thaum lub sijhawm ua haujlwm, kev ntsuas cua zoo yuav tsum tau ua kom tsis txhob nqus nws cov vapors.
- Hnav looj tsom iav thiab hnab looj tes thaum siv los tiv thaiv daim tawv nqaij thiab qhov muag khaus los ntawm kev sib cuag.
-Tsis txhob sib cuag nrog oxidants thiab qhov chaw tshav kub thaum khaws cia kom tsis txhob muaj hluav taws kub thiab tawg.
Thov nco ntsoov tias qhov no tsuas yog kev qhia yooj yim rau 4-[(Trifluoromethyl)-mercapto]-benzoic acid. Thaum siv thiab tuav cov tshuaj, nco ntsoov xa mus rau cov ntaub ntawv kev nyab xeeb tshwj xeeb thiab cov txheej txheem.
