Yellow 14 CAS 842-07-9 Cov ntaub ntawv
zoo
Benzo-2-naphthol, tseem hu ua Juanelli liab (Janus Green B), yog cov organic dye. Nws yog nyob rau hauv daim ntawv ntawm ntsuab crystalline hmoov uas yog soluble nyob rau hauv dej, cawv, thiab acidic media.
Benzoazo-2-naphthol muaj cov khoom nram qab no:
1. Dye khoom: benzoazo-2-naphthol yog cov organic dye siv dav hauv kev lag luam dye. Nws tuaj yeem cuam tshuam nrog cov ntaub ntawv xws li fibers, tawv, thiab ntaub los muab lawv cov xim tshwj xeeb.
2. pH teb: Benzo-2-naphthol qhia cov xim sib txawv ntawm pH sib txawv. Nyob rau hauv muaj zog acidic tej yam kev mob, nws muaj ib tug reddish xim; Nyob rau hauv tsis muaj zog acidic rau nruab nrab tej yam kev mob, nws yog ntsuab; Nyob rau hauv cov xwm txheej alkaline, nws yog xiav.
3. Kev ua lom lom: Benzo-2-naphthol muaj qee yam kev ua lom lom. Nws tau pom tias muaj cov tshuaj tiv thaiv kab mob rau qee cov kab mob thiab cov pwm, thiab tau siv dav hauv cell staining hauv thaj chaw ntawm biology thiab tshuaj.
4. Redox: Benzo-2-naphthol yog ib tug muaj zog txo tus neeg sawv cev uas muaj peev xwm oxidize nrog oxygen nyob rau hauv tsim nyog tej yam kev mob. Nws tseem tuaj yeem oxidized rau azo tebchaw los ntawm oxidants.
Feem ntau, benzoazo-2-naphthol yog ib qho tseem ceeb ntawm cov organic compound vim nws cov xim zoo nkauj thiab daim ntawv thov dav.
Siv cov txheej txheem synthesis
Benzo-2-naphthol yog ib qho organic fluorescent zas xim uas muaj ntau yam kev siv hauv kev tshawb fawb tshuaj lom neeg thiab lom neeg.
Txoj kev sib txuas ntawm benzoazo-2-naphthol feem ntau yog ua los ntawm cov kauj ruam hauv qab no:
1. Aniline yog reacted nrog nitrosohydroxylamine ntsev (tsim nyob rau hauv acidic tej yam kev mob) ntawm tsawg kub los tsim azo tebchaw.
Cov txiaj ntsig azo yog tom qab ntawd ua rau 2-naphthol nyob rau hauv alkaline tej yam kev mob los tsim benzoazo-2-naphthol.
Benzoazo-2-naphthol muaj ntau yam kev siv hauv kev siv tswv yim, suav nrog:
1. Cov ntaub ntawv Luminescent: Benzo-2-naphthol muaj cov khoom siv fluorescence zoo thiab tuaj yeem siv los npaj cov ntaub ntawv luminescent, xws li cov organic teeb-emitting diodes (OLEDs) thiab organic solar cells.
2. Cov khoom siv tso saib: Benzo-2-naphthol tuaj yeem siv rau hauv kev npaj cov organic nyias-film transistors (OTFTs), uas yog cov khoom siv nrog cov khoom siv hluav taws xob siab thiab yooj yim.
3. Biomarkers: Cov khoom fluorescent ntawm benzoazo-2-naphthol ua rau nws yog qhov kev xaiv zoo tshaj plaws rau biomarkers, uas tuaj yeem siv rau hauv kev tshawb fawb lom neeg xws li kev tshuaj xyuas ntawm tes, molecular probes, thiab lwm yam.
Cov ntaub ntawv kev nyab xeeb
Benzoazo-2-naphthol yog ib qho organic compound tseem hu ua PAN. Nov yog cov lus qhia txog nws cov ntaub ntawv kev nyab xeeb:
1. Toxicity: Benzo-2-naphthol muaj qee yam toxicity rau tib neeg lub cev thiab tej zaum yuav ua rau khaus thiab ua rau cov tawv nqaij, qhov muag thiab ua pa. Kev raug mob mus ntev lossis raug hnyav tuaj yeem ua rau muaj teeb meem kev noj qab haus huv.
2. Kev nqus pa: Cov plua plav lossis vapor ntawm benzoazo-2-naphthol tuaj yeem nqus tau los ntawm txoj hlab pa, ua rau ua pa ua pa, hnoos, ua tsis taus pa thiab lwm yam tsos mob. Kev nqus tau ntau dhau tuaj yeem ua rau lub ntsws puas.
4. Kev noj haus: Benzo-2-naphthol yuav tsum tsis txhob noj, uas yuav ua rau mob plab, ntuav, raws plab thiab lwm yam tsos mob. Nyob rau hauv cov ntaub ntawv ntawm kev huam yuaj, nrhiav kev kho mob tam sim ntawd.
5. Ib puag ncig: Benzo-2-naphthol muaj qee yam kev phom sij rau ib puag ncig, yog li nws yuav tsum tau ua tib zoo saib xyuas kom tsis txhob nkag mus rau hauv dej thiab av, thiab ua raws li cov cai tiv thaiv ib puag ncig thaum siv thiab pov tseg.
6. Cia thiab tuav: Benzo-2-naphthol yuav tsum tau muab cia rau hauv qhov chaw qhuav, txias, zoo-ventilated, deb ntawm qhov hluav taws kub thiab cov ntaub ntawv flammable. Cov thawv ntim khoom yuav tsum muab pov tseg kom zoo tom qab siv.
