Taw qhia
2-methyl-3-nitrotrifluorotoluene yog cov organic compound. 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:
- Cov tsos: Dawb crystalline khoom
- Solubility: Soluble nyob rau hauv cov organic solvents xws li ether, methanol thiab dimethyl sulfoxide
Siv:
- Nws kuj tuaj yeem siv los ua cov tshuaj reagent hauv cov tshuaj tiv thaiv kev sib xyaw ua ke, xws li lub hauv paus ntawm nitrous acid thiab sulfur dioxide.
Txoj kev:
- MTF feem ntau yog npaj los ntawm nitrification thiab fluorine hloov pauv ntawm benzoic acid. Ua ntej, benzoic acid yog nitrified kom tau 2-nitrobenzoic acid, thiab ces cov carboxyl pawg nyob rau hauv nitrobenzoic acid yog hloov mus rau hauv trifluoromethyl pawg los ntawm fluorine gas hloov tshuaj.
Cov ntaub ntawv kev nyab xeeb:
- MTF muaj qee yam toxicity thiab yuav ua rau muaj kev phom sij rau tib neeg lub cev, yog li nws yuav tsum tau ua tib zoo saib xyuas kev nyab xeeb thaum siv thiab ua haujlwm.
- Kev sib cuag nrog daim tawv nqaij, nqus tau, los yog kev noj tsis haum yuav ua rau khaus thiab raug mob, thiab yuav tsum tau ceev faj yog tias tsim nyog.
- Tsis txhob sib cuag nrog cov oxidizing muaj zog thiab combustibles los tiv thaiv hluav taws los yog tawg.
- Thaum siv thiab khaws cia, ua raws li cov txheej txheem kev nyab xeeb uas cuam tshuam.
