Yintoni iCyclopentanone CAS 120-92-3?

I-Cyclopentanone yaziwa ngokuba yi-Adipic Ketono. Ulwelo olunamafutha olungenambala olungenambala. Ukuba ne-etheric eyahlukileyo, ivumba elincinci elincinci.

Isicelo

I-1.Ukusuka kwi-cyclopentanone kunye ne-n-valeraldehyde njengezinto eziluhlaza, i-amyl cyclopentanone yenziwe yi-aldol condensation kunye nokuphelelwa ngamanzi emzimbeni, kwaye ke i-catalytic hydrogenation ekhethiweyo yenziwa ukuvelisa i-amyl cyclopentanone. I-Amyl cyclopentanone inevumba eliqinileyo lentyatyambo kunye neziqhamo kunye nencasa yejasmine, kwaye ingasetyenziswa kwifomula yencasa yekhemikhali yemihla ngemihla, idosi inokuba ngaphantsi kwama-20%. I-IFRA ayinayo imiqobo.

2. I-Hexylcyclopentanone ilungiswe ukusuka kwi-n-hexylaldehyde kunye ne-cyclopentanone nge-condensation kunye ne-hydrogenation ekhethiweyo. I-Hexylcyclopentanone inevumba eliqinileyo lejasmine kwaye ikhatshwa livumba leziqhamo, kwaye ingasetyenziswa kwi-perfume kunye nezinye iifomyula zemichiza yemihla ngemihla kunye nethamo ngaphakathi kwe-5%. I-IFRA ayinayo imiqobo.

3. I-1-pentene okanye i-1-heptene efunyenwe ngokuqhekeka kweparafini okanye ukuchithwa kotywala okuhambelanayo njengezinto eziluhlaza, phambi kwe-di-tert-butyl peroxide njenge-initiator, i-reaction yeqela elikhululekile kunye ne-cyclopentanone ukwenza i-2-amyl cyclopentanone (okanye I-2-heptyl cyclopentanone), emva kwe-oxidation ibe yi-delta-decalactone (okanye i-delta-dodecalactone).

4. Indlela yokudibanisa kunye ne-cyclopentanone njengeyona nto iqalayo inelona xabiso lemveliso yoshishino. I-Cyclopentanone iqala ukuxutywa nge-n-valeraldehyde, kwaye i-Chemicalbook ebangelwayo iphelelwe ngamanzi kwaye ikhethe i-hydrogenated ukwenza i-2-amylcyclopentanone, kwaye ekugqibeleni yenza i-delta-decalactone nge-oxidative ring enlargement.

I-5.delta-decanolactone isetyenziswa kakhulu kwi-flavour ye-flavour formulations, apho kukholelwa ukuba i-flavour ephawulekayo ye-cream yendalo. Ngaphambi koku, ixesha elide, i-perfumers yayilinganiselwe kuphela ekusebenziseni iziqholo ze-monomer ezifana ne-butanedione kunye ne-vanillin njengeyona nto iphambili yokulungiselela i-cream flavour. Nangona kunjalo, abantu ngokubanzi banomuvo wokuba incasa yekhrimu edibeneyo ingaphantsi kakhulu kunemveliso yendalo ngokwencasa okanye incasa. Kuphela emva kokusetyenziswa kwe-delta-decalactone, kunokubakho i-flavour yokwenyani yekhrimu, ngakumbi ukudibanisa kwe-delta-decalactone kunye ne-delta-dodecalactone njengeyona nto imnandi yezinto eziluhlaza, i-flavour kunye nefuthe le-flavour ye-cream elungiselelwe ingcono.

I-6.usebenzisa i-cyclopentanone kunye ne-valeraldehyde njengezinto eziluhlaza, i-condensation yokwenza i-2-(1-hydroxyl) i-amyl cyclopentanone, i-reaction kunye ne-dimethyl malonate, kunye ne-hydrolysis kwi-160 ~ 180℃, i-decarboxylated, i-esterification, i-dihydrojasmonate methyl ester ingalungiswa. I-Methyl jasmonate dihydrojasmonate yincasa yethutyana etyiwayo evunyelwe yi-GB2760-1996 kwilizwe lethu. Iphunga layo lingcono kune-methyl jasmonate yendalo, kwaye iipropati zayo zizinzile.
