Cyclhexanone yog dab tsi?
Cyclohexanone (CAS Nr.: 108-94-1)yog ib qho organic compound nrog covCov mis mos molecular C₆H₁₀Othiab molar mass ntawm 98.14 g / mol, thiab nws yog nyob rau hauv chav kawm ntawm alicyclic ketones nyob rau hauv uas ib tug rau -membered cyclohexane nplhaib muaj ib pawg methylene hloov los ntawm ib pab pawg neeg carbonyl (C=O), uas yog lub defining functional pab pawg neeg ntawm ketones.
Cyclohexanone yog ib qho siab - boiling hnyav nrog cov yam ntxwv evaporation tswj, thiab piv nrog qis - cov kuab tshuaj boiling xws li acetone los yog MEK, nws muab cov resin dissolution kev ua tau zoo dua rau epoxy, yas, thiab PVC systems, thaum tseem txhim kho cov zaj duab xis tsim, txo cov txheej txheem xws li blushing thiab qib siab; txheej txheej. Hauv cov ntawv thov kev lag luam, kwv yees li 90% ntawm lub ntiaj teb cyclohexanone ntau lawm yog siv hauv kev tsim cov caprolactam thiab KA roj derivatives, uas yog cov intermediates tseem ceeb hauv Nylon 6 thiab Nylon 66 ntau lawm, ua cyclohexanone yog cov khoom tseem ceeb nyob rau hauv lub ntiaj teb no polyamide mov saw.

Tus qauv ntawm cyclohexanone yog dab tsi?
CovCov qauv tshuaj ntawm cyclohexanonemuaj rau - koom nrog tsis yog-planar carbon nplhaib nyob rau hauv uas ib tug carbon atom yog sib koom ua ke rau ib pawg carbonyl (C=O), thiab cov qauv no muab kev ruaj ntseg ntawm ib tug saturated cyclohexane nplhaib nrog lub reactivity ntawm ib pawg ketone functional, uas yog lub luag hauj lwm rau nws cov tshuaj lom neeg tus cwj pwm nyob rau hauv kev lag luam tshuaj.
Hauv nws daim ntawv ruaj khov tshaj plaws, cyclohexanone txais yuav lub rooj zaum-zoo li kev sib haum xeeb zoo ib yam li cyclohexane txhawm rau txo qis lub nplhaib, txawm hais tias muaj cov pab pawg carbonyl me ntsis cuam tshuam qhov zoo tagnrho geometry ntawm lub nplhaib system.
Cov carbonyl carbon yog sp² hybridized thiab tsim ib tug trigonal planar geometry nrog daim ntawv cog lus kaum ntawm kwv yees li 120 degrees, thaum tshuav tsib carbon atoms nyob rau hauv lub nplhaib yog sp³ hybridized nrog tetrahedral geometry ntawm kwv yees li 109.5 degrees.
C=O daim ntawv cog lus yog cov polar heev vim yog electronegativity ntawm oxygen, uas ua rau cyclohexanone mus rau cov tshuaj ketone xws li nucleophilic ntxiv, oxidation, txo, thiab condensation tshwm sim.
Cyclhexanoneyog cov qauv sib txawv ntawm cyclohexane vim hais tias cyclohexane muaj cov qauv molecular C₆H₁₂ thiab tsis muaj cov pab pawg ua haujlwm, ua rau nws tsis tshua muaj tshwm sim, thaum cyclohexanone muaj pawg carbonyl uas ua rau nws cov tshuaj reactivity thiab muaj nqis.
Yuav ua li cas yog cyclohexanone ua industrially?
Cyclohexanone feem ntau yog tsim los ntawm oxidation ntawm cyclohexane, qhov twg benzene yog thawj hydrogenated los ua cyclohexane, uas yog ib nrab oxidized los tsim ib tug sib tov ntawm cyclohexanol thiab cyclohexanone hu ua KA roj, thiab qhov nruab nrab sib tov yog ntxiv ua tiav thiab sib cais los tsim caprolactam thiab ces siv cov adilon6 cov kua qaub, uas yog siv nyob rau hauv adipic acid. cyclohexanone yog ib qho tseem ceeb hauv nruab nrab ntawm tag nrho cov saw hlau no.
Dab tsi yog covkev siv cyclohexane?
Cyclohexanone feem ntau yog siv rau hauv cov nylon ntau lawm, qhov twg kwv yees li 90% ntawm lub ntiaj teb no noj yog qhia rau zus tau tej cov caprolactam thiab KA roj intermediates, uas yog ib qho tseem ceeb rau manufacturing Nylon 6 thiab Nylon 66 siv nyob rau hauv engineering plastics, textile fibers, thiab automotive Cheebtsam.
Nws kuj yog siv dav hauv kev ua haujlwm siab -kev ua haujlwm hnyav hauv txheej txheej, nplaum, inks, thiab PVC lossis CPVC cement systems vim nws muab cov kuab tshuaj muaj zog rau siab -molecular- hnyav resins, tswj evaporation tus nqi, thiab txhim kho nto leveling thiab zaj duab xis zoo.
Tsis tas li ntawd, cyclohexanone yog siv los ua cov tshuaj nruab nrab hauv kev tsim cov plasticizers, roj hmab tshuaj, tshuaj intermediates, thiab cov khoom tshwj xeeb.
Cov tshuaj tiv thaiv ntawm cyclohexanone
Cyclhexanone (CYC)tau txais ntau yam tshuaj lom neeg tseem ceeb xws li nucleophilic ntxiv cov tshuaj tiv thaiv nrog cov reagents xws li Grignard reagents thiab hydroxylamine, oxidation cov tshuaj tiv thaiv uas ua rau tsim cov adipic acid ntawm KA roj txoj kev, txo cov tshuaj tiv thaiv uas tsim cyclohexanol, thiab aldol condensation cov tshuaj tiv thaiv nyob rau hauv catalytic tej yam kev mob, tag nrho cov tseem ceeb nyob rau hauv industrial organic synthesis.

Puas yog Cyclhexanone Aromatic?
Cyclhexanone tsis yog ib qho tshuaj tsw qabvim nws tsis muaj conjugated π-electron system thiab tsis ua raws li Hückel txoj cai rau aromaticity, thiab yog li ntawd nws yog cais raws li ib tug non- aromatic alicyclic ketone.
Xaus
Cyclhexanone (C₆H₁₀O) yog ib tug cyclic ketone uas txhais los ntawm ib tug rau -membered carbon nplhaib uas muaj ib tug carbonyl pab pawg neeg, thiab cov qauv no muab ib tug tshwj xeeb tshuav nyiaj li cas ntawm stability thiab reactivity uas ua rau nws tseem ceeb nyob rau hauv nylon ntau lawm, muaj kuab tshuaj siv tshuaj, thiab tshuaj synthesis, thiab nws tseem yog ib tug tseem ceeb nruab nrab ntawm lub ntiaj teb no tshuaj kev lag luam vim nws lub hauv paus lub luag hauj lwm nyob rau hauv lub hauv paus ntawm polymer manufacturing thiab high{1} formulation systems.
