Kugwiritsa ntchito
Mwachidule;4-(4-methoxyphenyl)-2-butanone angagwiritsidwe ntchito pokonzekera 4-p-hydroxyphenyl-2-butanone, 4-p-hydroxyphenyl-2-butanone, wotchedwa rasipiberi ketone, pendant ketone, raspberry ketone (raspberryketone) , wopezedwa ndi Nomura et al.ku Japan mu 1918, adadziwika mu 1957 ngati chinthu chachikulu chonunkhira mu raspberries.
Njira yopanga: Rasipiberi ketone ndi dimethyl sulfate monga zopangira, etherification reaction kuti apange.
Kukonzekera:
1. condensation anachita ndi aniseed aldehyde, acetone ndi sodium hydroxide monga zopangira, pambuyo zimene anamaliza, m'munsi alkali wosanjikiza anapatukana, ndi chapamwamba mafuta ndi neutralized, kutsukidwa ndi distilled kuti achire zosungunulira kupeza aniseed butenone;
2. onjezerani anisyl butenone ku mowa wopanda madzi, onjezerani chothandizira ndi kusonkhezera zomwe zimachitika ndi haidrojeni, distill ndi kubwezeretsa zosungunulirazo zitatha.
Zitachitika izi, mowa wa anhydrous udabwezedwa ndi distillation kuti apeze mankhwala a hydrogenated anisyl acetone.
Anisyl acetone angagwiritsidwe ntchito pokonzekera rasipiberi ketone, kuphatikizapo ndondomeko zotsatirazi: anisyl acetone, potaziyamu hydroxide, N, N.
dimethylacetamide amathiridwa mu mbale youma ya tetra] yokhala ndi choyezera thermometer, chubu chogwetsera, ndi chubu choyatsa, chotenthedwa kuti chisungunuke, kenako ndikugwedezeka.
M'mikhalidwe yovuta, demethyl reagent idawonjezeredwa pang'onopang'ono ndipo cholimbacho chinasiyidwa kuti chisungunuke kwathunthu.Chosakanizacho chinasamutsidwa ku autoclave pansi pa chitetezo cha mpweya wa inert ndikuchitaponderezedwa.The osakaniza anachita anali neutralized kuti ndale, ndi mafuta gawo anali yotengedwa ndi distilled pansi pa kupanikizika yafupika kukonzekera rasipiberi ketone yaiwisi.Zopangidwa ndi rasipiberi ketone zidasungunuka ndi zosungunulira ndikuwunikiridwa kuti zipezeke rasipiberi ketone.Zokolola za kutulukira zinali
85.2%, ndipo chiyero cha mankhwala chinali 98 5%.
Anisylacetone ndi madzi opanda mtundu mpaka otumbululuka amafuta achikasu okhala ndi fungo lamaluwa ndi zipatso.Ndi wapakatikati wa dobutamine, amene tsopano makamaka ntchito monga zokometsera kukonzekera zosiyanasiyana zipatso oonetsera, ndi ntchito zakumwa zoziziritsa kukhosi, zakumwa zoziziritsa kukhosi, maswiti, kuphika zakudya ndi pudding zakudya.Ndi zokometsera zapamwamba kwambiri.Zimakopanso tizilombo monga scarabs.
