Taw qhia
2,2,2-Trifluoroethylamine yog cov organic compound nrog cov tshuaj formula C2H4F3N. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
1. Cov tsos mob: 2,2,2-Trifluoroethylamine yog cov kua dej tsis muaj xim.
2. Tsis hnov tsw: Nws muaj ib tug pungent tsw.
3. Ceev: 1.262g / mLat 20 ° C (lit.).
4. Boiling Point: 36-37 ° C (lit.)
5. Melting Point: -78 ° C.
6. Solubility: Yuav luag insoluble hauv dej, soluble hauv organic solvents xws li cawv, ethers thiab ketones.
Siv:
1. Daim ntawv thov hauv organic synthesis: 2,2,2-trifluoroethylamine tuaj yeem siv los ua ib qho amination reagent hauv organic synthesis rau kev qhia txog cov amino pawg.
3. Kev lag luam hluav taws xob: 2,2,2-trifluoroethylamine tuaj yeem siv los ua tus neeg saib xyuas, hnyav thiab tub yees hauv kev lag luam hluav taws xob.
Txoj kev:
Muaj ob txoj hauv kev npaj rau 2,2,2-trifluoroethylamine:
1. Los ntawm cov tshuaj fluorination cov tshuaj tiv thaiv: ethylamine raug rau cov roj fluorine, thiab fluorination yog ua raws li alkali catalysis kom tau 2,2,2-trifluoroethylamine.
2. Aminoation cov tshuaj tiv thaiv: 2,2,2-trifluoroethylamine yog npaj los ntawm reacting ammonia nrog 1,1,1-trifluoroethane nyob rau hauv lub xub ntiag ntawm ib tug catalyst.
Cov ntaub ntawv kev nyab xeeb:
1. 2,2,2-Trifluoroethylamine ua rau khaus ntawm daim tawv nqaij, qhov muag thiab ua pa, thiab yuav tsum tau muab yaug nrog dej ntau tam sim tom qab sib cuag.
2. Kev kis tau mus ntev tuaj yeem ua rau muaj kev phom sij rau kev noj qab haus huv thiab kev raug mob ntev yuav tsum zam.
3. Nws yuav tsum tau siv rau hauv qhov chaw uas muaj cua zoo thiab nyob deb ntawm qhov hluav taws kub.
4. Nws yuav tsum tau khaws cia kom zoo kom tsis txhob muaj oxidants thiab muaj zog alkalis.
5. Hnav tsom iav tiv thaiv, hnab looj tes thiab daim npog qhov ncauj tiv thaiv.
