Cyclamen aldehyde Siv Thiab Synthesis
tsw Diffusive thiab haib floral-ntsuab floral-stem-zoo li tsw nrog pronounced zaub, Cucumber-Melon-zoo li sau ntawv. Zuag qhia tag nrho zoo li tus ntxhiab ntawm Lindenblossom.
Kev piav qhia 2-Methyl-3-(p-isopropylphenyl) propionaldehyde muaj zog, paj tsw tsw. Tej zaum yuav tau npaj los ntawm condensation ntawm cuminic aldehyde thiab propionaldehyde tom qab hydrogenation nyob rau hauv lub xub ntiag ntawm ib tug catalyst.
Chemical Properties 2-Methyl-3-(p-isopropylphenyl)-propionaldehyde muaj zog, paj tsw tsw
Chemical Properties Cov khoom lag luam muaj nyob hauv racemate yog cov kua tsis muaj xim rau daj nrog cov ntxhiab tsw ntxhiab tsw ntawm Cyclamen europaeum (cyclamen, sowbread).
Ntau lawm. Ob txheej txheem tseem ceeb yog siv rau kev lag luam synthesis ntawm cyclamen aldehyde:
1) Alkaline condensation ntawm 4-isopropylbenzaldehyde thiab cov txiaj ntsig propanal, ntawm aldol, hauv kev tsim ntawm 2-methyl-3-(4-isopropylphenyl)-2-propenal. Lub unsaturated aldehyde yog hydrogenated xaiv rau saturated aldehyde nyob rau hauv lub xub ntiag ntawm poov tshuaj acetate thiab ib tug haum catalyst, xws li palladium-alumina:
2) Friedel-Crafts tshuaj tiv thaiv ntawm isopropylbenzene thiab 2-methylpropenal diacetate (methacrolein diacetate) nyob rau hauv lub xub ntiag ntawm titanium tetrachloride / boron trifluoride etherate muab cyclamen aldehyde enolacetate, uas yog hydrolyzed rau aldehyde:
Siv. Cyclamen aldehyde yog ib qho tseem ceeb rau kev tau txais cov paj tshwj xeeb hauv cov tshuaj tsw qab, tshwj xeeb tshaj yog hom cyclamen. Vim nws tshiab, floral nam, nws kuj yog siv los ua cov ntawv sau saum toj kawg nkaus hauv ntau lwm cov paj ntoo.
Qhov tshwm sim Tshaj tawm pom nyob rau hauv nutmeg thiab starfruit.
Siv Cyclamen Aldehyde yog ib qho muaj zog heev, floral, ntsuab ntawv siv nyob rau hauv ntau daim ntawv thov perfumery los muab rau hauv tshiab, paj, ntsuab los yog ozonic / marine accords. Nws yog ib qho khoom xyaw nrog kev siv loj zuj zus thiab qhov tseem ceeb hauv kev pab tsim kev hloov pauv rau cov ntaub ntawv ploj ntawm Perfumers 'palette. Cyclamen muaj kev ruaj ntseg zoo tag nrho tshwj tsis yog nyob rau hauv huab cua pH. Nws muaj zog tenacity thiab substantivity thiab sawv cev zoo heev tus nqi rau cov nyiaj nyob rau hauv cov creations tshiab. Ntxiv rau nws siv nyob rau hauv ntau naj hoom compositions, cyclamen aldehyde yog ib tug nruab nrab rau kev npaj ntawm fungicides thiab fungistatic tshuaj.
Siv Cyclamal, yog cov khoom xyaw hauv cov tshuaj tsw qab. Nws kuj tuaj yeem siv rau hauv kev sib txuas ntawm Cyclamen Cawv (C987655).
Txhais ChEBI: Xi-3-(4-Isopropylphenyl)-2-methylpropanal yog monoterpenoid.
Kev npaj Los ntawm condensation ntawm cuminic aldehyde thiab propionaldehyde tom qab hydrogenation nyob rau hauv lub xub ntiag ntawm ib tug catalyst.
Kev ruaj ntseg Profile Mob hnyav los ntawm kev noj tshuaj. Tib neeg daim tawv nqaij irritant. Saib ALDEHYDES thiab. Thaum rhuab mus rau decomposition nws emissions pa luam yeeb thiab irritating fumes.
