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

1. From cyclopentanone iyo n-valeraldehyde sida alaabta ceeriin, amyl cyclopentanone waxaa sameeyay aldol uumi iyo fuuqbaxa, ka dibna la doortay catalytic hydrogenation si loo soo saaro amyl cyclopentanone.Amyl cyclopentanone waxay leedahay ubaxyo xoog leh iyo caraf miro leh iyo dhadhan jasmine, waxaana loo isticmaali karaa caanaha dhadhanka kiimikada maalinlaha ah, qiyaasta waxay noqon kartaa wax ka yar 20%.IFRA ma laha wax xaddidaad ah.
2. Hexylcyclopentanone waxaa laga soo diyaariyey n-hexylaldehyde iyo cyclopentanone iyadoo la isticmaalayo uumi ka dibna hydrogenation xulashada.Hexylcyclopentanone waxay leedahay udgoon jasmine ah oo xooggan waxaana weheliya caraf miro, waxaana loo isticmaali karaa cadarka iyo qaababka kale ee dhadhanka kiimikaad ee maalinlaha ah iyada oo qiyaasta qiyaasta 5%.IFRA ma laha wax xaddidaad ah.
3. 1-pentene ama 1-heptene oo lagu helay dildilaaca paraffin ama fuuqbax u dhigma khamriga sida alaabta ceeriin, iyadoo ay joogaan di-tert-butyl peroxide sida bilawga, falcelinta isku darka kooxda xorta ah ee cyclopentanone si ay u sameeyaan 2-amyl cyclopentanone (ama 2-heptyl cyclopentanone), ka dib oksidation si ay u noqdaan delta-decalactone (ama delta-dodecalactone).
4. Waddada isku dhafka ah ee cyclopentanone sida alaabta bilawga ah waxay leedahay qiimaha wax soo saarka warshadaha ugu badan.Cyclopentanone ayaa marka hore lagu shubaa n-valeraldehyde, ka dibna Buugga Kiimikada ee ka soo baxa waa fuuqbaxa oo si door ah hydrogenated si loo sameeyo 2-amylcyclopentanone, iyo ugu dambeyntii si ay u sameeyaan delta-decalactone by ballaarinta giraanta oksaydhiyaha.
5.delta-decanolactone waxaa inta badan loo isticmaalaa habaynta dhadhanka cuntada, halkaas oo la aaminsan yahay in ay leedahay dhadhan sifa ah kareemka dabiiciga ah.Intaa ka hor, muddo dheer, cadar-bixiyeyaashu waxay ku koobnaayeen oo kaliya isticmaalka xawaashka monomer sida butanedion iyo vanillin oo ah alaabta ugu muhiimsan ee diyaarinta dhadhanka kareemka.Si kastaba ha ahaatee, dadku guud ahaan waxay dareemayaan in dhadhanka kareemka la isku daray uu aad uga yar yahay alaabta dabiiciga ah marka loo eego dhadhanka ama dhadhanka.Kaliya ka dib isticmaalka delta-decalactone, waxaa jiri kara dhadhan run ah oo kareem ah, gaar ahaan isku dhafka delta-decalactone iyo delta-dodecalactone sida alaabta ceeriin ee ugu weyn, dhadhanka iyo saameynta dhadhanka kareemka ee la diyaariyey ayaa ka sii fiican.
6. Isticmaalka cyclopentanone iyo valeraldehyde sida alaabta ceeriin, uumiga si loo sameeyo 2- (1-hydroxyl) amyl cyclopentanone, falcelinta dimethyl malonate, ka dibna hydrolysis at 160 ~ 180 ℃, decarboxylated, esterification, dihydrojasmonate methyl ester waa la diyaarin karaa.Methyl jasmonate dihydrojasmonate waa dhadhan la cuni karo oo ku meel gaar ah oo ay ogolaatay GB2760-1996 gudaha dalkeena.Udgoonkiisu wuu ka fiican yahay methyl jasmonate dabiiciga ah, hantidiisuna waa mid deggan.
200kg/Drum 20'FCL waxay qaadi kartaa 16 tan
