Application
Overview;4-(4-methoxyphenyl) -2-butanone inogona kushandiswa kugadzira 4-p-hydroxyphenyl-2-butanone, 4-p-hydroxyphenyl-2-butanone, inozivikanwawo seraspberry ketone, pendant ketone, raspberry ketone (raspberryketone) , yakawanikwa naNomura et al.muJapan muna 1918, yakaonekwa muna 1957 sechinhu chikuru chinonhuwira mu raspberries.
Maitiro ekugadzira: Raspberry ketone uye dimethyl sulfate seyakagadzirwa zvinhu, iyo etherification reaction yekugadzira.
Kugadzirira:
1. condensation reaction neaniseed aldehyde, acetone uye sodium hydroxide sezvinhu zvakasvibirira, mushure mokunge maitiro apera, chikamu chepasi che alkali chinoparadzaniswa, uye mafuta epamusoro haana kutorwa, akashambidzwa uye akasvibiswa kuti awanezve solvent kuti awane aniseed butenone;
2. wedzera anisyl butenone kune anhydrous doro, wedzera catalyst uye kurunga mhinduro nehydrogen, distill uye kudzorera solvent mushure mekuita.
Mushure mekuita, doro reanhydrous rakadzoserwa ne distillation kuti riwane iyo hydrogenated chigadzirwa anisyl acetone.
Anisyl acetone inogona kushandiswa kugadzira raspberry ketone, kusanganisira zvinotevera matanho chaiwo: anisyl acetone, potassium hydroxide, N, N.
dimethylacetamide inowedzerwa kune yakaoma tetra] vial ine thermometer, inodonhedza funnel, uye condensing chubhu, inopisa kuti inyunguduke, uye ipapo pasi pekukurudzira.
Mumamiriro ezvinhu anomutsa, iyo demethyl reagent yakawedzerwa zvishoma nezvishoma inodonha uye iyo yakasimba yakasiiwa kuti inyunguduke zvachose.Musanganiswa wacho wakaendeswa kune autoclave pasi pekuchengetedzwa kwegesi inert uye yakaita pasi pekumanikidzwa.Musanganiswa wekuita wakagadziriswa kuti usarerekera, uye chikamu chemafuta chakabviswa uye chakanyungudutswa pasi pekumanikidzwa kwakaderedzwa kugadzirira raspberry ketone crude.Chigadzirwa chisina kuchena che raspberry ketone chakanyungudutswa ne solvent uye chakanatswa kuti chiwane chakachena chigadzirwa che raspberry ketone.Chibereko chekugadzirwa chaive
85.2%, uye kuchena kwechigadzirwa kwaiva 98 5%.
Anisylacetone imvura isina ruvara kusvika kucheneruka ine mafuta ine maruva uye muchero.Iyo yepakati yedobutamine, iyo ikozvino inonyanya kushandiswa sezvinonhuwira kugadzira zvakasiyana siyana zvemichero zvinonaka, uye inoshandiswa muzvinwiwa zvinyoro, zvinwiwa zvinotonhorera, zvihwitsi, zvakabikwa chikafu uye pudding chikafu.Icho chinonhuwira chepamusoro-soro.Inokwezvawo zvipembenene zvakadai semakwara.
