Tirohanga whānui;Ka taea te whakamahi 4-(4-methoxyphenyl) -2-butanone ki te whakarite i te 4-p-hydroxyphenyl-2-butanone, 4-p-hydroxyphenyl-2-butanone, e mohiotia ana ano he raspberry ketone, ketone pendant, raspberry ketone (raspberryketone) , i kitea e Nomura et al.i Hapani i te tau 1918, i tohuhia i te tau 1957 ko te mea kakara nui i roto i nga raspberries.
Te tukanga whakaputa: Rahipere ketone me te dimethyl sulfate hei rauemi mata, te tauhohenga etherification ki te whakaputa.
Whakaritenga:
1. te tauhohenga condensation ki te aldehyde aniseed, te acetone me te konutai waikawa hei rauemi mata, i muri i te otinga o te tauhohenga, ka wehea te paparanga kawakore o raro, ka whakakorehia te hinu o runga, ka horoia, ka whakamarohia kia ora ai te whakarewa ki te whiwhi butenone aniseed;
2. tāpirihia te anisyl butenone ki te waipiro anhydrous, tāpirihia te whakakōkī me te whakaoho i te tauhohenga ki te hauwai, te whakamaroke me te whakaora i te whakarewa i muri i te tauhohenga.
I muri i te tauhohenga, ka whakahokia mai te waipiro anhydrous na roto i te whakamaarama kia whiwhi i te hua hauwai anisyl acetone.
Ka taea te whakamahi i te anisyl acetone ki te whakarite raspberry ketone, tae atu ki nga waahanga e whai ake nei: anisyl acetone, pāhare pāhare pāporo, N , N
Ka taapirihia te dimethylacetamide ki tetahi ipu tetra maroke kua oti te whakamaarama me te ine ine wera, te rewa topata, me te ngongo whakamahana, ka whakamahana kia memeha, katahi ka whakakorikoria.
I raro i nga tikanga whakakorikori, ka ata taapirihia te reagent demethyl ka waiho te totoka kia memeha katoa.I whakawhitia te ranunga ki te autoclave i raro i te whakamarumaru hau karekau ka tauhohe i raro i te pehanga.Ko te ranunga tauhohenga i whakakorehia ki te koretake, a ka tangohia te wahanga hinu, ka maturuhia i raro i te pehanga iti hei whakarite i te ketone raspberry.Ko te hua masivesivá o rōpere ketone i rewa ki te whakarewa me te tioata ki te whiwhi i te hua parakore o rōpere ketone.Ko te hua o te tenenga ko
85.2%, a ko te purenga hua ko 98 5%.
Ko te Anisylacetone he wai hinuhinu kore tae ki te kowhai kowhai me te kakara puawai me te kakara hua.He takawaenga o te dobutamine, e whakamahia ana i naianei hei mea kakara ki te whakarite i nga momo reka hua, ka whakamahia i roto i nga inu ngohengohe, nga inu makariri, nga rama, nga kai tunu me nga kai purini.He mea kakara ahua teitei.He kaikawe hoki mo nga pepeke penei i te scarabs.
