Taw qhia
2,3,4-Trifluorobenzoic acid yog cov organic compound. 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: 2,3,4-trifluorobenzoic acid yog cov xim tsis muaj kob crystalline.
- Solubility: Nws yog soluble hauv cov kuab tshuaj organic xws li ethers thiab cawv thiab me ntsis soluble hauv dej.
- Kev ruaj ntseg: zoo li ruaj khov ntawm chav tsev kub, tab sis tuaj yeem txo qis los ntawm cov oxidants muaj zog lossis txo cov neeg ua haujlwm ntawm qhov kub thiab txias.
- Ceev: approx. 1.63 g / cm³
Siv:
- 2,3,4-Trifluorobenzoic acid feem ntau yog siv los ua ib qho tseem ceeb nruab nrab ntawm cov organic synthesis.
- Nws kuj tseem siv tau los ua cov nplaim hluav taws xob hauv cov txheej, dyes, plastics, thiab polymers.
Txoj kev:
2,3,4-Trifluorobenzoic acid tuaj yeem npaj los ntawm txoj hauv kev hauv qab no:
- Benzoic acid yog reacted nrog trifluoroacetyl chloride los tsim 2,3,4-trifluorobenzoyl chloride.
- Tom qab ntawd, 2,3,4-trifluorobenzoyl chloride reacted nrog dej muab 2,3,4-trifluorobenzoic acid.
Cov ntaub ntawv kev nyab xeeb:
- Cov plua plav thiab vapor ntawm 2,3,4-trifluorobenzoic acid tuaj yeem ua rau khaus qhov muag, tawv nqaij thiab ua pa.
- Hnav cov cuab yeej tiv thaiv tus kheej tsim nyog xws li cov tsom iav tiv thaiv, hnab looj tes, thiab lub ntsej muag tiv thaiv thaum siv lossis tuav.
- Thaum raug rau qhov sib xyaw, qhov chaw cuam tshuam yuav tsum tau ntxuav tam sim nrog dej huv thiab kev kho mob yuav tsum tau nrhiav kom sai li sai tau.
- Thaum khaws cia thiab tuav, kev ntsuas kev nyab xeeb thiab cov txheej txheem yuav tsum raug soj ntsuam, xws li kev tswj xyuas qhov cua kom zoo thiab tsis txhob sib cuag nrog cov khoom tsis sib xws.
