1.Kubva ku cyclopentanone uye n-valeraldehyde sezvinhu zvakasvibirira, amyl cyclopentanone inoumbwa nealdol condensation uye kupera simba, uye ipapo kusarudza catalytic hydrogenation inoitwa kubudisa amyl cyclopentanone. Amyl cyclopentanone ine kunhuhwirira kwakasimba kwemaruva uye muchero uye jasmine flavour, uye inogona kushandiswa muzuva nezuva kemikari flavour formula, iyo dosage inogona kunge isingasviki 20%. IFRA haina zvirambidzo.
2. Hexylcyclopentanone inogadzirirwa kubva ku n-hexylaldehyde uye cyclopentanone kuburikidza nekugadzirisa uye zvino inosarudza hydrogenation. Hexylcyclopentanone ine kunhuhwirira kwakasimba kwejasmine uye inoperekedzwa nekunhuhwirira kwemichero, uye inogona kushandiswa mupefiyumu uye mamwe emazuva ese emakemikari flavour formulations pamwe nedosage mukati me5%. IFRA haina zvirambidzo.
3. 1-pentene kana 1-heptene inowanikwa neparafini inoputika kana inofananidzwa nedoro dehydration sezvinhu zvakasvibirira, pamberi pe di-tert-butyl peroxide sekutanga, boka rakasununguka rinowedzera maitiro ne cyclopentanone kuumba 2-amyl cyclopentanone (kana 2-heptyl cyclopentanone), mushure mekuita oxidation kuva delta-decalactone (kana delta-dodecalactone).
4. Nzira yekubatanidza ine cyclopentanone sechinhu chekutanga chine kukosha kwakanyanya kwekugadzirwa kwemaindasitiri. Cyclopentanone inotanga kunyungudutswa nen-valeraldehyde, uye inoguma Chemicalbook inopera mvura uye inosarudza hydrogenated kuti iite 2-amylcyclopentanone, uye pakupedzisira inogadzira delta-decalactone neoxidative ring enlargement.
5.delta-decanolactone inonyanya kushandiswa mukugadzirwa kwekunaka kwezvokudya, uko kunotendwa kuti kune unhu hwekunaka kwekrimu yakasikwa. Izvi zvisati zvaitika, kwenguva yakareba, vagadziri vaingogumira pakushandisa monomer zvinonhuwira zvakadai sebutanedione uye vanillin sechinhu chikuru chekugadzirwa kwekrimu inonaka. Nekudaro, vanhu vanowanzonzwa kuti yakasanganiswa cream flavour ishoma pane yechisikigo chigadzirwa maererano nekuravira kana kuravira. Chete mushure mekushandiswa kwedelta-decalactone, panogona kuve nekunakirwa kwechokwadi kwekrimu, kunyanya kusanganiswa kwedelta-decalactone uye delta-dodecalactone sechinhu chikuru chinonhuwira mbishi, kunhuhwirira uye mhedzisiro yekirimu inonaka yakagadzirwa zviri nani.
6.kushandisa cyclopentanone uye valeraldehyde sezvinhu zvakasvibiswa, condensation kuumba 2- (1-hydroxyl) amyl cyclopentanone, inopindirana ne dimethyl malonate, uye ipapo hydrolysis pa 160 ~ 180 ℃, decarboxylated, esterification, dihydrojasmonate methyl ester inogona kugadzirirwa. Methyl jasmonate dihydrojasmonate inguva inodyiwa inonaka inobvumidzwa neGB2760-1996 munyika yedu. Kunhuhwirira kwayo kuri nani pane yakasikwa methyl jasmonate, uye zvinhu zvayo zvakagadzikana.
200kg/drum 20'FCL inogona kubata matani gumi nematanhatu
