1.Mai i te cyclopentanone me te n-valeraldehyde hei rauemi mata, ka hangaia te amyl cyclopentanone e te condensation o te aldol me te whakamaroketanga, katahi ka mahia te hauwaitanga catalytic whiriwhiri hei whakaputa i te amyl cyclopentanone. Ko te Amyl cyclopentanone he kaha te kakara o te puawai me te huarākau me te hā jasmine, ka taea te whakamahi i roto i te tātai hā matū ia rā, ka iti ake i te 20%. Karekau he here a IFRA.
2. Ka whakaritea te Hexylcyclopentanone mai i te n-hexylaldehyde me te cyclopentanone na roto i te whakakoi, katahi ka kowhiria te hauwai. He kaha te kakara o te Hexylcyclopentanone me te kakara o nga hua, a ka taea te whakamahi i roto i te hinu kakara me etahi atu hanga matū o ia ra me te inenga i roto i te 5%. Karekau he here a IFRA.
3. Ko te 1-pentene, te 1-heptene ranei ka riro mai i te paraffin paraffin, i te whakamaroketanga o te waipiro e rite ana hei rauemi mata, i te aroaro o te di-tert-butyl peroxide hei kaikaiti, ko te tauhohenga taapiri kore utu me te cyclopentanone ki te hanga 2-amyl cyclopentanone (ranei 2-heptyl cyclopentanone), i muri i te hāoratanga ka huri hei delta-decalactone (te delta-dodecalactone ranei).
4. Ko te huarahi whakahiato me te cyclopentanone hei mea timatanga ko te tino uara whakaputa ahumahi. Ko te Cyclopentanone te tuatahi ka whakapoapoa ki te n-valeraldehyde, ka mutu te hua o te Chemicalbook ka whakamarokehia, ka kowhiria te hauwai hei hanga i te 2-amylcyclopentanone, ka mutu ka hanga delta-decalactone ma te whakarahi mowhiti oxidative.
Ko te 5.delta-decanolactone te nuinga e whakamahia ana i roto i nga waihanga kai reka, i reira e whakaponohia ana kei a ia te ahua o te kirīmi taiao. I mua i tenei, mo te wa roa, he iti noa te whakamahi i nga mea kakara mo te monomer penei i te butanedione me te vanillin hei tino rauemi mo te whakarite i te kakara kirīmi. Heoi, ko te nuinga o te whakaaro he iti ake te reka o te kirīmi whakaranu i te hua maori i runga i te reka me te reka. I muri noa iho i te whakamahinga o te delta-decalactone, ka puta he reka pono o te kirīmi, ina koa ko te whakakotahitanga o te delta-decalactone me te delta-dodecalactone hei mea tino kakara, he pai ake te reka me te paanga o te kirikiri kua oti te whakarite.
6.ma te whakamahi i te cyclopentanone me te valeraldehyde hei rauemi mata, te condensation ki te hanga i te 2-(1-hydroxyl) amyl cyclopentanone, te tauhohenga me te dimethyl malonate, katahi ka hydrolysis i te 160 ~ 180 ℃, decarboxylated, esterification, dihydrojasmonate methyl ester ka taea te whakarite. Ko te Methyl jasmonate dihydrojasmonate he kakara kai mo te wa poto e whakaaetia ana e GB2760-1996 i to tatou whenua. He pai ake tona kakara i te methyl jasmonate maori, a ka pumau ona taonga.
200kg/drum 20'FCL ka taea te pupuri 16 tons
