Hexanal (Tshuaj mis Consula C ₆ H ₁₂ ₁₂, tus lej lej 66-25-1) yog cov kua tsis muaj xim thiab pob tshab nrog lub pungent tsw. Nws muaj lub ntsiab lus npau npau ntawm txog 130℃ntawm chav tsev kub thiab lub ntsej muag ntawm 32 degree. Nws yog insoluble hauv dej tab sis yooj yim soluble hauv cov kuab tshuaj muaj zog xws li ethanol thiab ether. Raws li ib qho tseem ceeb muaj cov organic synthemes, nws siv cov khoom siv ntau, xws li kev lag luam thiab cov khoom noj khoom haus, kev tshawb fawb ua liaj ua teb, ua liaj ua teb thiab tshuaj ua liaj ua teb. Nrog rau kev sib tawg ntawm ntsuab tshuaj thev naus laus zis, nws cov ntawv sau xwm txheej yog txuas ntxiv.
Caproobdehydeyog cov txuj ci tseem ceeb ntawm cov txuj lom hluavtaws, tus cwj pwm sib xyaw ua ke ntawm cov nyom thiab Fruity Aromas, zoo ib yam li aroma ntawm freshly txiav nyom lossis cov txiv av tshiab. Hauv kev lag luam khoom noj khoom haus, nws yog dav siv los npaj kua, txiv lws suav, khaub noom txias, khaub noom, ci zaub mov thiab pudding cov khoom lag luam. Raws li GB 2760- 1996 tus qauv nws yog qhov muaj txiaj ntsig ib ntus: rau cov khoom noj kom txias ib ntus Thiab rau paj npleg nws yog 2.0-2.5 mg / kg. Piv txwv li, hauv cov kua tsw roj carbonated, 0.5-1.0 mg / kg ntawm n-hexanal tuaj yeem muab cov khoom noj muaj ntxhiab tsw qab zib tsis muaj cov tshuaj tsw qab muaj ntxhiab.
Hauv kev ua haujlwm txhua yam tshuaj lom neeg txhua hnub, nws yog ib qho tseem ceeb raw rau high- Cov tshuaj tsw qab, xab npum, ntxuav thiab cov tshuaj tsw qab, cov tshuaj tsw qab. Nws cov ntxhiab tsw yog ntev - ntev thiab muaj cov khoom xyaw nrog cov khoom xyaw xws li ib txhiab tus nplua nuj thiab fawm kib. Piv txwv li, ib hom khaub ncaws txawv ntawm cov tshuaj ntxhua khaub ncaws ntxiv 0.3% n {nplooj ntoo rov qab muab cov dej nag 27 ntxiv rau hauv cov neeg tau txais txiaj ntsig zoo nrog aroma.
Ntxiv rau yog cov khoom siv raw ntawm essence, nws tseem ua lub luag haujlwm ntawm tsw ntawm kev ua zaub mov. Hauv cov nqaij cov khoom, qhov ntau npaum li cas ntawm 0.01 {}} 0.05% tuaj yeem npog cov ntses tsis hnov ntses thiab txhim kho cov tsw ntuj ntawm cov nqaij. Piv txwv li, hauv kev tsim cov nqaij npua ntau lawm, n {{} hexanal thiab sodium glutamate ua haujlwm ua ke los ua kom cov khoom qab ntsev thiab qab ntsev, thiab txo qhov siv ntawm cov ntsiab lus los ntawm 30%. Nyob rau hauv kev lag luam mis nyuj, n-hexanal yog siv rau flasing cov khoom noj siv mis nyuj zoo xws li cov mis nyuj khov. Nws qhov kev rhaub dej npau npau tsawg tso cai rau lub aroma kom sai sai tso tawm ntawm cov khoom siv kub tsawg, txhim kho cov neeg siv khoom.
Ntau tus neeg sau ntawv yog nws ua haujlwm tshwj xeeb. Kev tshawb fawb tau pom tias nws tuaj yeem cuam tshuam qhov kev loj hlob ntawm cov txiv kab ntxwv ntxig hauv ntau lub neej ntawm 0.1 {}} 0.5 mmol / l. Piv txwv li, hauv kev sim cov khoom sib xyaw, cov txiv hmab txiv ntoo Cov xeeb ceem no ua rau nws muaj peev xwm hloov rau cov khoom txuag ntuj.
Ib tug kws tshaj lij hauv kev ua haujlwm hauv kev noj tshuaj thiab kev noj qab haus huv
Daim ntawv thov ntawm n - hexanal hauv cov chaw muag tshuaj yog kev hloov los ntawm cov kev daws teeb meem ib txwm muaj rau cov khoom xyaw. Nws cov kev kawm ua haujlwm tau lees paub los ntawm kev tshawb fawb ntau yam: Qhov tsawg kawg nkaus cov kab mob pathogenic thiab escherichia coli yog 0.5} 2.0 mg, uas ua tau zoo dua li qee cov tshuaj tua kab mob. Raws li cov xeeb ceem no, ib qho kev lag luam qee yam tau tsim cov kab mob tua kab uas muaj n-hexanal rau kev tiv thaiv thiab tswj cov citrus anthracnose. Kev sim teb tau qhia txog kev ua tau zoo ntawm 83% thiab yog tus phooj ywg ib puag ncig.
Hauv kev tshawb fawb biomedical, nws yog ib qho cuab yeej tseem ceeb rau kev kawm ntawm tes teeb liab. Nws tuaj yeem sim xws li cov khoom lag luam laspid Piv txwv li, hauv Alzheimer tus qauv tus qauv, cov hlwb neuronal kho nrog cov qib siab tseem ceeb, muab cov lus qhia tshiab rau kev kawm ntawm cov kab mob ntawm cov kab mob.
Cov yuam sij cuam tshuam hauv cov ntaub ntawv txuj ci
Raws li ib qho khoom siv hluav taws xob nruab nrab, nws cov ntawv thov hauv cov ntaub ntawv npog ntau cov lus qhia xws li roj hmab, plastics, resins, thiab lubricants, thiab roj nplua nyeem, thiab roj ci. Hauv cov roj av kev lag luam, nws tuaj yeem txuas ntxiv cov kev pabcuam lub neej ntawm cov khoom lag luam ua tshuaj antioxidant nce ntxiv ntawm 65% rau 82% hauv 70℃kev sim ua haujlwm. Nyob rau hauv lub teb ntawm cov huab cua, muaj kub kub {{{{{}} Cov resins tuaj yeem npaj los ntawm cov khoom siv ntsuas kub (tg)
Ib qho kev thov tawg ntau ntxiv nyob rau hauv synthesis ntawm optoelectronic cov ntaub ntawv. Los ntawm Aldol Khaub Ncaws Cov tshuaj tiv thaiv,caproobdehydeYuav hloov dua siab tshiab rau hauv 2 {{{{4 4}} butyl {}}}} {10-estyl-1-{10-{10-{10-} Ib qho kev lag luam ua lag luam siv N-hexanal txoj kev los tsim 2-butyl-1-octanol nrog kev ua kom zoo nkauj ntawm 99.5%, uas tau ua rau cov panels uas muaj kev sib txoos thiab tawg ua cov thev naus laus zis.
Cov ntawv thov tshiab hauv lub teb ntawm kev ua liaj ua teb thiab kev tiv thaiv ib puag ncig
Hauv kev ua liaj ua teb, cov tshuaj tua kab ntawm n {- hexanal yog siv los tsim cov tshuaj tua kab ntsuab. Nws cov kev sib cuag tua cov haujlwm LC ₀ ₀ Tawm tsam cov kab xws li cov kab ntawv cabbillars thiab aphids yog 12.5 mg / l, thiab nws muaj kev nyab xeeb rau cov kab muaj txiaj ntsig zoo li cov muv. Piv txwv li, qee lub tuam txhab tua tsiaj rau N ingou}} hexanal nrog azadirachtin los ua kom muaj kev tswj hwm ntawm 58%, nce ntxiv ntawm 23 feem pua cov ntsiab lus piv rau ib tus neeg sawv cev.
Hauv kev tiv thaiv kev tiv thaiv ib puag ncig, nws yog qhov "nqus tsev ntxhua khaub ncaws" rau kev kho mob ntawm cov organic cov tebchaw (vocs). Nws tuaj yeem tsim kev tshuaj ntsuam catalytic nrog ozone los tsim cov pa roj carbon dioxide thiab dej, nrog cov tshuaj tiv thaiv cov tshuaj tiv thaiv ntawm 1.2 ⁻¹⁴ cm ³ ³ / (Molecule · s). Lub n {{4 4}} hexanal raws li cov tuam txhab tiv thaiv ntawm 92% thiab tuaj yeem siv ntau dua 50 zaug, muab cov tshuaj tshiab rau sab hauv huab cua.

Nws yog ib qho siv cov qauv chromoography feem ntau (GC) tsom xam, siv rau ntsuas ntsuas qhov ntsuas thiab cov tshuaj ntsuam xyuas zoo thiab muaj txiaj ntsig. Nws qhov cub npau npau yog qhov nruab nrab thiab nws cov tshuaj lom neeg yog qhov ruaj khov, ua rau nws tsim nyog rau kev kuaj pom ntawm Aldehyde tebchaw. Piv txwv li, hauv kev kuaj pom ntawm formaldehyde seem nyob rau hauv cov khoom noj, siv n {} mg / kg / kg thiab nce qhov tseeb los ntawm peb zaug. Tsis tas li ntawd, n {- hexanal kuj tseem siv rau kev tshawb fawb tshuab ntawm witig thiab aldol cov kev cuam tshuam, raws li cov qauv sib txuas los qhia cov kab hluavtaw.
Cov synthesis ntawmcaproobdehydeYog tau los ntawm reacting hexylrithium thiab formaldehyde nyob rau hauv cov kub thiab cov kev tshuaj tiv thaiv. Cov hauv qab no yog ob txoj kev ua tau hluavtaws:
1. Khoom cua ntawm Hexanal los ntawm hydrogenation txo ntawm Hexan-1-ol:
(1). Synthesis ntawm Hexan-1-ol:
Ua ntej txo hydrogenation txo, peb yuav tsum tau ua raws li hexan-1-ol ua ntej. Hexan-1-ol tuaj yeem npaj los ntawm reacting hexylmagnesium halide nrog acetic anhydride hauv tetrahydrofuran (thf).
Cov tshuaj tiv thaiv cov tshuaj tiv thaiv muaj raws li nram no:
Hexylmagnesium haretic anhydride → hexan-1-ol + magnesium acetate haletate hawj
(2). Hydrogenation Txo:
Dissolve Hexan-1-ol nyob rau hauv ethanol, ntxiv cov tshuaj catalyst hydrogalyst (xws li pd / c), foob cov hlab ntawm cov hlab ntsha thiab ntxiv hydrogen. Tom qab cov tshuaj tiv thaiv tiav, lim thiab distill kom tau txais hexanal.
2. Synthesize hexanal los ntawm reacting hexylrithium thiab formaldehyde:
(1). Kev npaj ntawm hexylrithium:
Hexylrithium tuaj yeem tau txais los ntawm reacting n- hexylal Halides nrog lithium bromoacetate hauv cyclohexane.
Cov tshuaj tiv thaiv cov tshuaj tiv thaiv muaj raws li nram no:
n - hexyl halide + lithium bromoacetate → hexylilithad + sodium chloride + Acetone
(2). Cov tshuaj tiv thaiv ntawm hexylithium thiab formaldehyde:
Teb cov npaj hexylrithium hauv TetranahyDroTuran qhuav, ntxiv formaldehyde thiab do cov tshuaj tiv thaiv. Tom qab cov tshuaj tiv thaiv tiav, lim thiab distill kom tau txais hexanal.
Cov tshuaj tiv thaiv cov tshuaj tiv thaiv muaj raws li nram no:
Hexylrithium + Formaldehyde → Hexanal + Lioh
CaproobdehydeNws yuav tsum raug sau tseg tias rau cov kev sib tw saum toj no xws li kev kub siab, thiab lwm lub sijhawm, kev ua kom tau raws li cov txiaj ntsig thiab kev coj dawb huv ntawm cov khoom kawg. Hauv kev ua haujlwm tiag, nws yuav tsum tau ua kom zoo raws li qhov xwm txheej tshwj xeeb.
