Codsiga
Dulmar;4- (4-methoxyphenyl) -2-butanone waxaa loo isticmaali karaa si loogu diyaariyo 4-p-hydroxyphenyl-2-butanone, 4-p-hydroxyphenyl-2-butanone, oo sidoo kale loo yaqaan ketone raspberry, pendant ketone, raspberry ketone (raspberryketone) , waxaa daahfuray Nomura et al.Japan 1918kii, waxaa loo aqoonsaday 1957 inay tahay walaxda udgoon ee raspberries.
Habka wax soo saarka: Raspberry ketone iyo dimethyl sulfate sida alaabta ceeriin, falcelinta etherification si ay u soo saaraan.
Diyaarinta:
1. falcelinta uumiga leh aniseed aldehyde, acetone iyo sodium hydroxide sida alaabta ceeriin, ka dib marka falcelinta la dhammeeyo, lakabka hoose ee alkali waa la kala soocaa, iyo saliidda sare waa dhexdhexaad, la dhaqo iyo distilled si ay u soo kabsado dareeraha si ay u helaan aniseed butenone;
2. ku dar anisyl butenone aalkolada anhydrous, ku dar kicinta oo ku walaaq falcelinta hydrogen, dhalaali oo soo kabso dareeraha ka dib falcelinta.
Falcelinta ka dib, khamriga anhydrouska ah ayaa lagu soo kabsaday iyadoo la nadiifinayo si loo helo alaabta hydrogenated anisyl acetone.
Anisyl acetone waxaa loo isticmaali karaa in lagu diyaariyo ketone raspberry, oo ay ku jiraan tallaabooyinka soo socda ee gaarka ah: anisyl acetone, potassium hydroxide, N, N
dimethylacetamide waxa lagu daraa weel qallalan oo tetra ah oo ku qalabaysan heerkulbeeg, maro tuur, iyo tuubo qaboojin, kulayl si ay u milmaan, ka dibna hoos walaaq
Xaaladaha walaaqda, reagent demethyl si tartiib ah ayaa loogu daray hoos waxaana loo daayay inuu si buuxda u milmo.Isku darka ayaa loo wareejiyay autoclave hoos yimaada ilaalinta gaaska aan shaqaynayn oo ay uga falcelisay cadaadis.Isku darka falcelinta ayaa la dhexdhexaadiyey si dhexdhexaad ah, iyo marxaladda saliidda ayaa la soo saaray oo lagu miiray cadaadis la dhimay si loo diyaariyo ceyriinka ketone raspberry.Alaabta ceeriin ee ketone raspberry waxaa lagu milmay dareere iyo crystallized si loo helo badeecada saafiga ah ee ketone raspberry.Wax-soo-saarka hal-abuurku wuxuu ahaa
85.2%, iyo nadiifnimada alaabtu waxay ahayd 98 5%.
Anisylacetone waa dareere saliid leh oo huruud ah oo aan midab lahayn oo cirro leh oo leh ubaxyo iyo caraf miro leh.Waa dhexdhexaad ah dobutamine, taas oo hadda inta badan loo isticmaalo sida xawaashka si loogu diyaariyo dhadhanka khudradaha kala duwan, waxaana loo isticmaalaa cabitaannada fudud, cabitaannada qabow, nacnaca, cuntooyinka la dubay iyo cuntooyinka pudding.Waa uunsi heerkiisu sareeyo.Waxa kale oo ay soo jiidataa cayayaanka sida nabarrada.
