Incamake;4-. , byavumbuwe na Nomura n'abandi.mu Buyapani mu 1918, byagaragaye mu 1957 nk'ibintu nyamukuru bihumura neza muri raspberries.
Uburyo bwo kubyaza umusaruro: Raspberry ketone na dimethyl sulfate nkibikoresho fatizo, reaction ya etherification kubyara.
Imyiteguro:
1. reaction ya condensation hamwe na aniseed aldehyde, acetone na sodium hydroxide nkibikoresho fatizo, nyuma yo kubyitwaramo birangiye, igice cyo hepfo ya alkali kiratandukana, kandi amavuta yo hejuru ntabogamye, arakaraba kandi arasukurwa kugirango agarure umusemburo kugirango abone butenone;
2. ongeramo anisyl butenone kuri alcool ya anhydrous, ongeramo catalizator hanyuma ukangure reaction hamwe na hydrogène, gusiba no kugarura ibishishwa nyuma yo kubyitwaramo.
Nyuma yo kubyitwaramo, inzoga ya anhydrous yagaruwe no kuyungurura kugirango ibone hydrogenated anisyl acetone.
Anisyl acetone irashobora gukoreshwa mugutegura ketone ya raspberry, harimo intambwe zikurikira: anisyl acetone, potasiyumu hydroxide, N, N
dimethylacetamide yongewe kuri tetra yumye] vial ifite ibikoresho bya termometero, guta umuyoboro, hamwe numuyoboro wa kondegene, gushyushya gushonga, hanyuma bikabikwa.
Mubihe bitera imbaraga, reagent ya demethyl yongewemo buhoro buhoro hanyuma igikomere gisigara gishonga burundu.Uruvange rwimuriwe muri autoclave irinda gazi inert kandi rwakorewe igitutu.Uruvangitirane rwa reaction rwabangamiwe kutagira aho rubogamiye, kandi icyiciro cya peteroli cyarakuweho kandi kiragabanywa kubera umuvuduko muke wo gutegura igikoma cya ketone.Ibicuruzwa bitavanze bya raspberry ketone byashongeshejwe hamwe na solge hanyuma bigashyirwa muburyo bwo kubona umusaruro mwiza wa raspberry ketone.Umusaruro wavumbuwe wari
85.2%, naho ibicuruzwa byera byari 98 5%.
Anisylacetone ni ibara ritagira ibara ryijimye ryumuhondo wijimye hamwe nindabyo n'imbuto.Ni intera ya dobutamine, ubu ikoreshwa cyane cyane nk'ikirungo cyo gutegura uburyohe butandukanye bw'imbuto, kandi ikoreshwa mu binyobwa bidasembuye, ibinyobwa bikonje, bombo, ibiryo bitetse n'ibiryo bya pudding.Nibirungo byo murwego rwohejuru.Nibikurura kandi udukoko nka scarabs.
