Cyclopentanone CAS 120-92-3
Cyclopentanone izwi kandi ku izina rya Adipic Ketono. Ni amazi y'amavuta adafite ibara kandi abonerana. Afite impumuro yihariye kandi isa n'umunyu.

1. Kuva kuri cyclopentanone na n-valeraldehyde nk'ibikoresho fatizo, amyl cyclopentanone ikorwa na aldol condensation no kubura amazi, hanyuma hagakorwa hydrogenation ya selective catalytic kugira ngo hakorwe amyl cyclopentanone. Amyl cyclopentanone ifite impumuro ikomeye y'indabyo n'imbuto hamwe n'uburyohe bwa jasmine, kandi ishobora gukoreshwa mu buryo bwa buri munsi bwo kuryoha kw'ibinyabutabire, igipimo gishobora kuba munsi ya 20%. IFRA nta mbogamizi igira.
2. Hexylcyclopentanone ikorwa muri n-hexylaldehyde na cyclopentanone binyuze mu gushonga hanyuma hifashishijwe hydrogenation itoranijwe. Hexylcyclopentanone ifite impumuro ikomeye ya jasmine kandi iherekejwe n'impumuro y'imbuto, kandi ishobora gukoreshwa mu mibavu n'indi miterere ya buri munsi y'ibinyabutabire bifite ingano iri hagati ya 5%. IFRA nta mbogamizi igira.
3. Pentene 1 cyangwa hepetene 1 iboneka binyuze mu gucika kwa parafini cyangwa kubura amazi mu mubiri nk'ibikoresho fatizo, iyo hari di-tert-butyl peroxide nk'itangiza, ihinduka ry'itsinda ryigenga hamwe na cyclopentanone rigakora 2-amyl cyclopentanone (cyangwa 2-heptyl cyclopentanone), nyuma yo gushonga ikaba delta-decalactone (cyangwa delta-dodecalactone).
4. Uburyo bwo gukora cyclopentanone nk'ibikoresho byo gutangira bufite agaciro kanini mu nganda. Cyclopentanone ibanza guhuzwa na n-valeraldehyde, hanyuma Chemicalbook ivamo irashiramo amazi hanyuma igahinduka hydrogen kugira ngo ikore 2-amylcyclopentanone, hanyuma amaherezo igakora delta-decalactone binyuze mu kongera impeta ya oxidative.
5.delta-decanolactone ikoreshwa cyane cyane mu buryo bwo kuryoha ibiryo, aho bivugwa ko ifite uburyohe bwihariye bwa cream karemano. Mbere y'ibi, kuva kera, abakora parufe bari bagengwa gusa n'ikoreshwa ry'ibirungo bya monomer nka butanedione na vanillin nk'ibikoresho by'ibanze byo gutegura uburyohe bwa cream. Ariko, muri rusange abantu bumva ko uburyohe bwa cream ivanze ari buke cyane ugereranyije n'uburyohe karemano mu bijyanye n'uburyohe cyangwa uburyohe. Nyuma yo gukoresha delta-decalactone, ni bwo hashobora kubaho uburyohe nyabwo bwa cream, cyane cyane uruvange rwa delta-decalactone na delta-dodecalactone nk'impumuro nyamukuru y'ibikoresho karemano, uburyohe n'ingaruka by'uburyohe bwa cream butegurwa biba byiza kurushaho.
6. Gukoresha cyclopentanone na valeraldehyde nk'ibikoresho fatizo, gushonga bikarema 2-(1-hydroxyl) amyl cyclopentanone, gukorana na dimethyl malonate, hanyuma hidrolise kuri 160 ~ 180℃, decarboxylated, esterification, dihydrojasmonate methyl ester irashobora gutegurwa. Methyl jasmonate dihydrojasmonate ni uburyohe bw'igihe gito bwo kuribwa bwemewe na GB2760-1996 mu gihugu cyacu. Impumuro yayo ni nziza kurusha methyl jasmonate karemano, kandi imiterere yayo irahamye.
