Isicelo
Uhlolojikelele;I-4-(4-methoxyphenyl)-2-butanone ingasetshenziselwa ukulungisa i-4-p-hydroxyphenyl-2-butanone, 4-p-hydroxyphenyl-2-butanone, eyaziwa nangokuthi i-raspberry ketone, i-pendant ketone, i-raspberry ketone (i-raspberryketone) , etholwe nguNomura et al.eJapane ngo-1918, kwatholakala ngo-1957 njengento eyinhloko yephunga elimnandi kuma-raspberries.
Inqubo yokukhiqiza: I-raspberry ketone ne-dimethyl sulfate njengezinto zokusetshenziswa, ukusabela kwe-etherification ukukhiqiza.
Ukulungiselela:
1. ukusabela kwe-condensation nge-aniseed aldehyde, i-acetone ne-sodium hydroxide njengezinto zokusetshenziswa, ngemva kokuba ukusabela kuqediwe, ungqimba lwe-alkali oluphansi luyahlukaniswa, futhi uwoyela ongaphezulu awuthathi hlangothi, ugezwe futhi uhlanjululwe ukuze ubuyisele i-solvent ukuze uthole i-aniseed butenone;
2. engeza i-anisyl butenone kutshwala obungenamanzi, engeza i-catalyst futhi ugovuze ukusabela nge-hydrogen, distill futhi ubuyisele isincibiliki ngemva kokusabela.
Ngemuva kokusabela, utshwala obungenamanzi butholakale ngokuxutshwa ukuze kutholwe umkhiqizo we-hydrogenated anisyl acetone.
I-Anisyl acetone ingasetshenziswa ukulungisa i-raspberry ketone, kuhlanganise nezinyathelo ezithile ezilandelayo: i-anisyl acetone, i-potassium hydroxide, i-N, i-N.
i-dimethylacetamide yengezwa ebhodleleni elomile le-tetra] elifakwe i-thermometer, ifaneli ewisayo, neshubhu elijiya, lishisiswe ukuze lincibilike, bese liyanyakaziswa.
Ngaphansi kwezimo ezinyakazayo, i-demethyl reagent yengezwa kancane kancane futhi okuqinile kwashiywa ukuba kuncibilike ngokuphelele.Ingxube idluliselwe ku-autoclave ngaphansi kokuvikelwa kwegesi engasebenzi futhi yasabela ngaphansi kwengcindezi.Ingxube yokusabela yayingathathi hlangothi ukuze ingathathi hlangothi, futhi isigaba samafutha sakhishwa futhi sahlanjululwa ngaphansi kwengcindezi encishisiwe ukuze kulungiswe okusajingijolo okuluhlaza kweketone.Umkhiqizo ongahluziwe we-raspberry ketone wahlakazwa nge-solvent futhi wacwecwa ukuze uthole umkhiqizo omsulwa we-raspberry ketone.Isivuno sokusungulwa kwaba
85.2%, kanti ukuhlanzeka komkhiqizo kwaba ngama-98 5%.
I-Anisylacetone iwuketshezi olunamafutha angenambala kuya kokuphuzi okuphaphathekile olunephunga elimnandi lezimbali.Kuyi-intermediate ye-dobutamine, manje esetshenziswa kakhulu njengesinongo ukulungisa ukunambitheka kwezithelo okuhlukahlukene, futhi isetshenziswa eziphuzweni ezibandayo, iziphuzo ezibandayo, amaswidi, ukudla okubhakiwe kanye nokudla kwe-pudding.Kuyizinongo ezisezingeni eliphezulu uma kuqhathaniswa.Iphinde ihehe izinambuzane ezifana nama-scarabs.
