Taw qhia
4-Nitro-3-trifluoromethylaniline, tseem hu ua TNB (Trinitrofluoromethylaniline), 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: Dawb mus rau lub teeb daj muaju los yog hmoov
- Solubility: me ntsis soluble hauv dej, soluble hauv organic solvents xws li ethanol, acetone, thiab lwm yam
- Stability: Relatively ruaj rau lub teeb, tshav kub thiab huab cua, tab sis raug rau ya raws thiab tawg
Siv:
- 4-Nitro-3-trifluoromethylaniline yog dav siv los ua ib feem ntawm cov pib thiab cov khoom tawg, piv txwv li, nws tuaj yeem siv los hloov TNT (trinitrotoluene). Nws muaj lub zog tawg siab thiab ruaj khov hauv thaj chaw ntawm cov khoom tawg.
Txoj kev:
- Los ntawm aniline, trifluoromethanesulfonic acid yog thawj reacted nrog cuprous bromide los ua trifluoromethylaniline. Tom qab ntawd, trifluoromethylaniline reacted nrog nitric acid, nitrobenzene ntxiv, thiab tom qab nitrite acid kho, 4-nitro-3-trifluoromethylaniline thaum kawg tau.
Cov ntaub ntawv kev nyab xeeb:
- 4-Nitro-3-trifluoromethylaniline yog cov khoom tawg thiab suav tias yog tawg thiab yuav tsum tau siv ceev faj.
- Thaum tuav thiab khaws cia, tsis txhob ua kom muaj hluav taws xob lossis hluav taws xob hluav taws xob.
- Tsis txhob sib cuag nrog cov tshuaj tua hluav taws, oxidants thiab alkaline tshuaj uas tuaj yeem ua rau muaj kev phom sij txaus ntshai.
- Kev nqus pa, noj, lossis kev sib cuag ntawm daim tawv nqaij thiab qhov muag yuav muaj kev phom sij, yuav tsum tau hnav cov khoom tiv thaiv tus kheej tsim nyog thaum ua haujlwm.
