Fa'aaogāga
Vaaiga Aoao;4-(4-methoxyphenyl) -2-butanone e mafai ona faʻaaogaina e saunia ai le 4-p-hydroxyphenyl-2-butanone, 4-p-hydroxyphenyl-2-butanone, e taʻua foi o le raspberry ketone, pendant ketone, raspberry ketone (raspberryketone) , maua e Nomura et al.i Iapani i le 1918, na faailoaina i le 1957 o le mea manogi autu i raspberries.
Gaosiga gaioiga: Raspberry ketone ma dimethyl sulfate e pei o mea mata, le tali etherification e maua ai.
Sauniuniga:
1. condensation tali ma aniseed aldehyde, acetone ma sodium hydroxide e pei o mea mata, ina ua uma le tali, ua tuueseeseina le vaega pito i lalo o le alkali, ma o le suauu pito i luga ua neutralized, fufuluina ma faamamaina e toe maua le solvent e maua ai le aniseed butenone;
2. faaopoopo anisyl butenone i le ava malosi, faaopoopo catalyst ma faaosofia le tali i le hydrogen, faamama ma toe maua le solvent pe a uma le tali.
Ina ua mae'a le tali, na toe maua mai le 'ava malosi e ala i le fa'amama ina ia maua ai le oloa fa'a-hydrogenated anisyl acetone.
Anisyl acetone e mafai ona faʻaaogaina e saunia ai le ketone raspberry, e aofia ai laasaga faʻapitoa nei: anisyl acetone, potassium hydroxide, N, N
o le dimethylacetamide ua faaopoopo i se fagu mago tetra] ua saunia i se fua vevela, faʻafefete faʻafefe, ma faʻamaʻi faʻaofuofu, faʻavevela e faʻamavae, ona faʻafefe ai lea.
I lalo o tulaga faʻavevesi, o le demethyl reagent na faʻapipiʻi malie i lalo ma tuʻu le malo e solo atoa.O le paluga na faʻafeiloaʻi i se autoclave i lalo o le puipuiga o le kesi ma faʻafefe i lalo o le mamafa.O le fa'afefiloiga tali sa fa'aitu'u i le fa'aitu'u, ma le vaega o le suau'u na fa'amama ma fa'amama i lalo o le fa'aitiitia o le mamafa e saunia ai le ketone crude.O le oloa mama o le rasipi ketone na fa'amavaeina i le solvent ma tioata e maua ai le oloa mama o le rasipi ketone.O le fua o le mea fou na maua
85.2%, ma o le mama oloa sa 98 5%.
Anisylacetone ose vai suau'u e leai se lanu e samasama samasama ma se manogi fuga ma fua.O se vaega o le dobutamine, lea ua masani ona faʻaaogaina e fai ma mea manogi e saunia ai fualaau suamalie eseese, ma faʻaaogaina i meainu suamalie, meainu malulu, lole, meaʻai tao ma meaʻai pudding.O se mea manogi maualuga maualuga.E fa'atosina fo'i iniseti pei o ma'ila.
