alpha-Ionone (URUBANZA # 127-41-3) amakuru
Violet ketone, izwi kandi nka benzophenone, ni ifumbire mvaruganda. Hano hari amakuru yumutekano yerekeye ionone:
1. Uburozi: Violet ketone ifite uburozi runaka kumubiri wumuntu. Irashobora kwangiza sisitemu yo hagati yumwijima nu mwijima, kandi irashobora kugira ingaruka mbi kuri sisitemu yimyororokere ninsoro.
2. Impanuka zo guhumeka: Guhumeka umwuka cyangwa umukungugu wa ionone birashobora gutera ibimenyetso bitameze neza nko kuzunguruka, gusinzira, gukorora, no guhumeka neza. Kumara igihe kirekire bishobora kwangiza sisitemu yo hagati.
3. Hamagara hazard: Violet ketone irashobora kwinjizwa muruhu. Kumara igihe kirekire cyangwa guhura cyane bishobora gutera uruhu n'amaso. Ibikoresho bikwiye byo kurinda umuntu nka gants na gogles z'umutekano bigomba kwambarwa mugihe ukoresha ionone.
4. Ingamba zo kuzimya umuriro: Mugihe hamenetse cyangwa umuriro, koresha ifu yumye, ifuro cyangwa dioxyde de carbone kugirango uzimye umuriro. Irinde gukoresha amazi, kuko violet ketone ifata amazi kugirango itange imyuka yaka.
5. Kujugunya imyanda: Kujugunya imyanda ya violet ketone neza ukurikije amategeko n’ibanze. Ntukayijugunye mu miyoboro cyangwa mu myanda.
6. Kwirinda ububiko: Ketone ya Violet igomba kubikwa ahantu hakonje, humye, hafite umwuka uhumeka neza, kure yumuriro wumuriro na okiside.
Aya makuru ni ayerekanwa gusa. Niba hakenewe ubundi gukoresha cyangwa gutunganya ionone, nyamuneka reba urupapuro rwumutekano rujyanye kandi ubaze umunyamwuga.
kamere
Violet ketone, izwi kandi nka linaylketone, ni ketone isanzwe. Nibintu nyamukuru bigize impumuro yindabyo za violet.
Violet ketone ni ibara ritagira ibara ryumuhondo wamavuta yumuhondo uhindagurika mubushyuhe bwicyumba.
Violet ketone irashobora gushonga muri alcool na ether solver, kandi igashonga gato mumazi. Ubucucike bwabwo buri hasi, hamwe n'ubucucike bwa 0.87 g / cm ³. Yumva urumuri kandi irashobora gukurura imirasire ya ultraviolet.
Violet ketone irashobora guhindurwamo okiside kuri ketone alcool cyangwa acide muburyo bwa chimique, kandi irashobora kugabanuka kuri alcool binyuze muburyo bwo kugabanya hydrogenation. Irashobora guhura na alkylation na esterification reaction hamwe nibintu byinshi.
Gukoresha no guhuza uburyo
Violet ketone (izwi kandi nka ketone yumutuku) ni uruganda rwa ketone. Ifite impumuro idasanzwe kandi ikoreshwa kenshi mubikorwa bya parufe na parufe. Ibikurikira nintangiriro yo gukoresha no guhuza uburyo bwa ionone:
Intego:
Parufe n'ibirungo: ibiranga impumuro nziza ya ionone, ikoreshwa cyane mubikorwa bya parufe nibirungo kugirango ikore ibicuruzwa bihumura neza.
Uburyo bwa Synthesis:
Synthesis ya ionone muri rusange igerwaho hakoreshejwe uburyo bubiri bukurikira:
Oxidation ya Nucleobenzene: Nucleobenzene (impeta ya benzene ifite insimburangingo ya methyl) ikorerwa reaction ya okiside, nko gukoresha aside ya okiside cyangwa umuti wa potasiyumu permanganate acide, kugirango ubyare ionone.
Kwishyira hamwe kwa Pyrylbenzaldehyde: Pyrylbenzaldehyde (nka benzaldehyde hamwe nimbaraga za pyridine zasimbuwe na para cyangwa meta) zifatwa na anhydride ya acetike hamwe nizindi reaction ziterwa na alkaline kugirango zibe ionone.
