4-Biphenylcarbonyl chloride (CAS # 14002-51-8) Kev taw qhia
xwm:
-Cov tsos mob: tsis muaj xim rau cov kua daj daj.
- Soluble hauv cawv, ethers, thiab chlorinated hydrocarbons.
Lub hom phiaj:
4-biphenylformyl chloride yog ib qho tseem ceeb organic synthesis reagent feem ntau siv nyob rau hauv cov synthesis ntawm benzoyl chloride thiab nws cov derivatives. Nws tuaj yeem siv rau cov ntawv thov hauv qab no:
-Raws li tus neeg sawv cev crosslinking rau cov nplaum, polymers, thiab roj hmab.
-Siv los tiv thaiv pab pawg tshem tawm cov tshuaj tiv thaiv hauv cov organic synthesis cov tshuaj tiv thaiv.
Txoj kev tsim khoom:
4-biphenylformyl chloride tuaj yeem npaj los ntawm reacting aniline nrog formic acid. Cov tshuaj tiv thaiv tuaj yeem ua rau cua sov biphenylamine thiab formic acid ntawm qhov kub thiab txias, thiab ntxiv cov catalysts xws li ferrous chloride lossis carbon tetrachloride kom nrawm cov tshuaj tiv thaiv.
Cov ntaub ntawv kev ruaj ntseg:
-4-biphenylformyl chloride yog cov organic hluavtaws reagent thiab belongs rau qeb ntawm irritating gases. Tiv tauj lossis nqus tau cov khoom no tuaj yeem ua rau khaus qhov muag, tawv nqaij, thiab ua pa.
-Thaum siv 4-biphenylformyl chloride, thov hnav cov khoom tiv thaiv tsim nyog xws li hnab looj tes, tsom iav tiv thaiv, thiab lub npog ntsej muag tiv thaiv.
-4-Biphenylformyl chloride yuav tsum muab khaws cia kom deb ntawm qhov hluav taws kub thiab hauv qhov chaw txias, qhov cua zoo. Tsis txhob kov ncaj qha rau ntawm daim tawv nqaij thiab qhov muag, thiab tsis txhob nqus lawv cov vapors.
-Yog tias raug 4-biphenylformyl chloride, tam sim ntawd yaug qhov chaw cuam tshuam nrog dej txaus thiab nrhiav kev kho mob sai.
