Cyclopentanone CAS 120-92-3
E mōhiotia ana hoki te Cyclopentanone ko Adipic Ketono. He wai hinuhinu mārama, kore tae. He kakara motuhake, he kakara miniti.

1. Mai i te cyclopentanone me te n-valeraldehyde hei rauemi mata, ka hangaia te amyl cyclopentanone mā te whakapūpūtanga aldol me te whakamaroke, kātahi ka mahia te hauwaiwaitanga catalytic whiriwhiri hei whakaputa i te amyl cyclopentanone. He kakara putiputi me te hua kaha te Amyl cyclopentanone me te reka jasmine, ā, ka taea te whakamahi i roto i te tauira reka matū o ia rā, ka taea te iti iho i te 20% te horopeta. Kāore he here a IFRA.
2. Ka hangaia te Hexylcyclopentanone mai i te n-hexylaldehyde me te cyclopentanone mā te whakatōtō, kātahi ka whakahauwaihia. He kakara kaha te Hexylcyclopentanone, ā, he kakara hua anō hoki, ā, ka taea te whakamahi i roto i te hinu kakara me ētahi atu hanganga kakara matū o ia rā, me te inenga i roto i te 5%. Kāore he here a te IFRA.
3. Ko te 1-pentene, 1-heptene rānei i whiwhihia mā te pakaru paraffin, mā te whakamaroke waipiro rānei hei rauemi mata, i te aroaro o te di-tert-butyl peroxide hei tīmatanga, ka tauhohe te tāpiri rōpū kore utu ki te cyclopentanone hei hanga i te 2-amyl cyclopentanone (2-heptyl cyclopentanone rānei), i muri i te waikura ka huri hei delta-decalactone (delta-dodecalactone rānei).
4. Ko te ara hanga me te cyclopentanone hei rauemi tīmatanga te mea tino nui te uara whakaputa ahumahi. Ka whakakōpirihia tuatahitia te cyclopentanone ki te n-valeraldehyde, ā, ka whakamaroketia te hua, ka whakahauwaihia kia hanga he 2-amylcyclopentanone, ā, hei whakamutunga, kia hanga he delta-decalactone mā te whakanui i te mowhiti oxidative.
5. Ko te delta-decanolactone te mea e whakamahia nuitia ana i roto i ngā whakatakotoranga reka kai, e whakaponohia ana he rite te reka ki te kirīmi tūturu. I mua atu i tēnei, mō te wā roa, ko ngā kaihanga kakara anake i whakamahia ko ngā mea kakara monomer pēnei i te butanedione me te vanillin hei rauemi matua mō te hanga reka kirīmi. Heoi, ko te whakaaro o te iwi he iti ake te reka o te kirīmi whakaranu i te hua tūturu i runga i te reka, i te kakara rānei. I muri i te whakamahinga o te delta-decalactone, ka taea te puta he reka tūturu o te kirīmi, inā koa ko te whakakotahitanga o te delta-decalactone me te delta-dodecalactone hei rauemi matua mō te kakara, ka pai ake te reka me te pānga o te reka kirīmi kua oti te whakarite.
6. Mā te whakamahi i te cyclopentanone me te valeraldehyde hei rauemi mata, ka whakapūpūhia hei hanga i te 2-(1-hydroxyl) amyl cyclopentanone, ka tauhohe ki te dimethyl malonate, kātahi ka hydrolysis i te 160 ~ 180℃, ka wetewetehia te carboxylation, ka taea te whakarite i te dihydrojasmonate methyl ester. Ko te methyl jasmonate dihydrojasmonate he reka kai rangitahi kua whakaaetia e GB2760-1996 i tō tātou whenua. He pai ake tōna kakara i te methyl jasmonate tūturu, ā, he pumau ōna āhuatanga.
200kg/pahu 20'FCL ka taea te pupuri i te 16 tana
