Chemical Structure ntawm Acetonitrile
Acetonitrile muaj cov tshuaj formula (C2H3N). Nws cov qauv muaj ib pawg methyl ((CH_3)) sib koom ua ke rau pawg cyano ((-C≡N)). Cov pa roj carbon - nitrogen triple daim ntawv cog lus hauv pawg cyano muaj zog heev, nrog rau lub zog ntawm kwv yees li 891 kJ / mol. Cov ntawv cog lus muaj zog no muab acetonitrile qee yam tshuaj lom neeg thiab lub cev. Lub linear kev npaj ntawm pawg (C≡N) ua rau lub molecule polar, nrog ib tug dipole lub sij hawm ntawm txog 3.92 D. Qhov polarity no tseem ceeb vim nws cuam tshuam nws cov solubility thiab reactivity.
Kev siv Acetonitrile (C2H3N)
- Acetonitrile yog siv los ua ib qho hnyav hauv cov txheej txheem rho tawm ntawm hydrocarbons.
- Nws yog siv los cais fatty acids los ntawm cov roj zaub.
- Siv los ua cov tshuaj tsw qab.
- Nws yog dav siv nyob rau hauv zus tau tej cov hluavtaws pharmaceuticals.
- Nws yog siv rau hauv kev tsim cov roj hmab.
- Nws yog siv nyob rau hauv refining thiab extraction ntawm tooj liab.
- Siv los ua cov kuab tshuaj hauv cov hlwb electrochemical.
