Yellow 14 CAS 842-07-9 Zambiri

khalidwe
Benzo-2-naphthol, yemwenso amadziwika kuti Juanelli red (Janus Green B), ndi utoto wachilengedwe. Ndiwo mawonekedwe a ufa wobiriwira wa crystalline womwe umasungunuka m'madzi, mowa, ndi acidic media.

Benzoazo-2-naphthol ili ndi zotsatirazi:

1. Zida za utoto: benzoazo-2-naphthol ndi utoto wachilengedwe womwe umagwiritsidwa ntchito kwambiri pamakampani opanga utoto. Imatha kulumikizana ndi zinthu monga ulusi, zikopa, ndi nsalu kuti zipatse mtundu wina wake.

2. Kuyankha kwa pH: Benzo-2-naphthol imawonetsa mitundu yosiyanasiyana pamitundu yosiyanasiyana ya pH. Mumikhalidwe ya acidic kwambiri, imakhala ndi mtundu wofiyira; Pansi pofooka acidic ku ndale, ndi wobiriwira; Pansi pa zinthu zamchere, zimakhala zabuluu.

3. Zochita Zachilengedwe: Benzo-2-naphthol ili ndi zochitika zina zamoyo. Zapezeka kuti zili ndi antimicrobial zotsatira pa mabakiteriya ena ndi nkhungu, ndipo zimagwiritsidwa ntchito kwambiri pakudetsa ma cell m'magulu a biology ndi mankhwala.

4. Redox: Benzo-2-naphthol ndi mphamvu yochepetsera yomwe imatha kutulutsa okosijeni pansi pamikhalidwe yoyenera. Itha kukhalanso oxidized kuti azophatikizana ndi ma okosijeni.

Nthawi zambiri, benzoazo-2-naphthol ndi gawo lofunikira la organic chifukwa cha mawonekedwe ake abwino a utoto komanso malo ambiri opaka utoto.

Ntchito ndi kaphatikizidwe njira
Benzo-2-naphthol ndi utoto wa fulorosenti womwe umagwiritsidwa ntchito mosiyanasiyana mu kafukufuku wa sayansi ya zamankhwala ndi zachilengedwe.

Njira yophatikizira ya benzoazo-2-naphthol nthawi zambiri imachitika ndi izi:

1. Aniline amachitidwa ndi mchere wa nitrosohydroxylamine (wopangidwa pansi pa acidic mikhalidwe) pa kutentha kochepa kuti apange mankhwala a azo.

Chifukwa cha azo pawiri ndiye anachita ndi 2-naphthol pansi pa zinthu zamchere kupanga benzoazo-2-naphthol.

Benzoazo-2-naphthol ali ndi ntchito zosiyanasiyana zothandiza, kuphatikizapo:

1. Zida zopangira luminescent: Benzo-2-naphthol ili ndi mphamvu zabwino za fluorescence ndipo ingagwiritsidwe ntchito pokonzekera zipangizo zounikira, monga organic light-emitting diodes (OLEDs) ndi maselo a dzuwa.

2. Zida zowonetsera: Benzo-2-naphthol ingagwiritsidwe ntchito pokonzekera ma transistors a organic thin-film (OTFTs), omwe ndi zipangizo zowonetsera zokhala ndi ma electron apamwamba komanso kusinthasintha.

3. Ma biomarkers: Mphamvu ya fluorescent ya benzoazo-2-naphthol imapanga chisankho choyenera kwa zolembera zamoyo, zomwe zingagwiritsidwe ntchito pofufuza zamoyo monga kujambula kwa selo, ma probe a molekyulu, ndi zina zotero.

Zambiri Zachitetezo
Benzoazo-2-naphthol ndi mankhwala omwe amadziwikanso kuti PAN. Nawa mawu oyambira pazachitetezo chake:

1. Poizoni: Benzo-2-naphthol ali ndi poizoni wina m'thupi la munthu ndipo akhoza kukhala ndi zotsatira zokhumudwitsa komanso zowononga pakhungu, maso ndi kupuma. Kuwonekera kwa nthawi yayitali kapena kuwonekera kwambiri kungayambitse matenda aakulu.

2. Inhalation: Fumbi kapena nthunzi wa benzoazo-2-naphthol amatha kutengeka ndi njira yopuma, kuchititsa kupuma, kutsokomola, kupuma movutikira ndi zizindikiro zina. Kupuma kwambiri kumatha kuwononga mapapo.

4. Kudya: Benzo-2-naphthol sayenera kulowetsedwa, zomwe zingayambitse kupweteka kwa m'mimba, kusanza, kutsegula m'mimba ndi zizindikiro zina. Ngati mwamwa mowa mwangozi, pitani kuchipatala mwamsanga.

5. Chilengedwe: Benzo-2-naphthol ili ndi zoopsa zina zomwe zingathe kuwononga chilengedwe, choncho m'pofunika kusamala kuti zisalowe m'madzi ndi nthaka, ndikutsatira malamulo otetezera chilengedwe pogwiritsira ntchito ndi kutaya.

6. Kusungirako ndi kusamalira: Benzo-2-naphthol iyenera kusungidwa pamalo owuma, ozizira, opanda mpweya wabwino, kutali ndi magwero a moto ndi zipangizo zoyaka moto. Zotengera ziyenera kutayidwa bwino mukatha kugwiritsa ntchito.
