Cyclopentanone CAS 120-92-3
Cyclopentanone waxaa sidoo kale loo yaqaan Adipic Ketono. Dareere saliid leh oo aan midab lahayn oo hufan. Leh ur gaar ah oo etheric ah, oo xoogaa yar oo mint ah.

1. Laga soo bilaabo cyclopentanone iyo n-valeraldehyde oo ah walxo ceeriin ah, amyl cyclopentanone waxaa sameeya isku-darka aldol iyo fuuq-baxa, ka dibna waxaa la sameeyaa hydrogenation-ka catalytic-ga ee xulashada ah si loo soo saaro amyl cyclopentanone. Amyl cyclopentanone waxay leedahay caraf udgoon ubaxeed iyo miro leh iyo dhadhan jasmine ah, waxaana loo isticmaali karaa qaacidada dhadhanka kiimikada maalinlaha ah, qiyaasta waxay noqon kartaa wax ka yar 20%. IFRA ma laha wax xaddidaad ah.
2. Hexylcyclopentanone waxaa laga sameeyaa n-hexylaldehyde iyo cyclopentanone iyadoo la isticmaalayo isku-darka ka dibna hydrogenation-ka la xushay. Hexylcyclopentanone wuxuu leeyahay caraf udgoon oo jasmine ah oo xooggan waxaana la socda caraf udgoon oo miro ah, waxaana loo isticmaali karaa cadarka iyo qaacidooyinka kale ee dhadhanka kiimikada maalinlaha ah iyadoo qiyaasta lagu qiyaasay ay tahay 5%. IFRA ma laha wax xaddidaad ah.
3. 1-pentene ama 1-heptene oo laga helo dildilaaca paraffin ama fuuq-baxa khamriga ee u dhigma sida walxaha ceeriin ah, iyadoo ay joogaan di-tert-butyl peroxide oo ah bilowe, falcelinta kooxda xorta ah ee cyclopentanone si ay u sameeyaan 2-amyl cyclopentanone (ama 2-heptyl cyclopentanone), ka dib marka oksaydhku noqdo delta-decalatone (ama delta-dodecalactone).
4. Wadada isku-darka ee cyclopentanone oo ah walaxda bilowga ah waxay leedahay qiimaha wax-soo-saarka warshadaha ugu badan. Cyclopentanone waxaa marka hore lagu daraa n-valeraldehyde, ka dibna Chemicalbook-ka ka dhasha waa la fuuq-baxaa oo si xulasho leh ayaa loo daadiyaa si loo sameeyo 2-amylcyclopentanone, ugu dambayntiina wuxuu sameeyaa delta-decalactone iyadoo la kordhinayo giraanta oksaydhka.
5.delta-decanolactone waxaa inta badan loo isticmaalaa qaacidooyinka dhadhanka cuntada, halkaas oo la aaminsan yahay inay leedahay dhadhanka gaarka ah ee kareemka dabiiciga ah. Kahor tan, muddo dheer, cadar-sameeyayaasha waxay ku koobnaayeen oo keliya isticmaalka xawaashyada monomer sida butanedione iyo vanillin oo ah walxaha ugu muhiimsan ee lagu diyaariyo dhadhanka kareemka. Si kastaba ha ahaatee, dadku guud ahaan waxay dareemayaan in dhadhanka kareemka isku dhafan uu aad uga yar yahay badeecada dabiiciga ah marka loo eego dhadhanka ama dhadhanka. Kaliya ka dib isticmaalka delta-decalactone, ma jiri kartaa dhadhan dhab ah oo kareem ah, gaar ahaan isku-darka delta-decalatone iyo delta-dodecalactone oo ah walxaha ugu muhiimsan ee caraf udgoonka, dhadhanka iyo saameynta dhadhanka kareemka la diyaariyey ayaa ka wanaagsan.
6. Isticmaalka cyclopentanone iyo valeraldehyde sida walxo cayriin ah, isku-darka si loo sameeyo 2-(1-hydroxyl) amyl cyclopentanone, falcelinta dimethyl malonate, ka dibna hydrolysis heerkul ah 160 ~ 180℃, decarboxylated, esterification, dihydrojasmonate methyl ester waa la diyaarin karaa. Methyl jasmonate dihydrojasmonate waa dhadhan ku meel gaar ah oo la cuni karo oo uu ogol yahay GB2760-1996 dalkeenna. Carafkeedu wuu ka fiican yahay methyl jasmonate dabiiciga ah, sifooyinkiisuna waa kuwo deggan.
