Yellow 14 CAS 842-07-9 Ulwazi
umgangatho
I-Benzo-2-naphthol, eyaziwa ngokuba yiJuanelli ebomvu (i-Janus Green B), idayi yendalo. Ikwimo ye-crystalline powder eluhlaza enyibilikayo emanzini, utywala, kunye nemithombo ye-acidic.
I-Benzoazo-2-naphthol ineempawu ezilandelayo:
1. Iimpawu zedayi: i-benzoazo-2-naphthol yidayi yendalo esetyenziswa kakhulu kwishishini ledayi. Iyakwazi ukunxulumana nezinto ezinje ngeentsinga, ufele, kunye namalaphu ukubanika umbala othile.
I-2. Ukuphendula kwe-pH: I-Benzo-2-naphthol ibonisa imibala eyahlukeneyo kwiimpawu ezahlukeneyo ze-pH. Kwiimeko ezinzima ze-asidi, inombala obomvu; Ngaphantsi kwe-acidic ebuthakathaka kwiimeko ezingathathi hlangothi, iluhlaza; Ngaphantsi kweemeko ze-alkaline, iblue.
3. Umsebenzi we-Biological: I-Benzo-2-naphthol inomsebenzi othile we-biological. Ifunyaniswe ukuba ineempembelelo ze-antimicrobial kwezinye iibhaktheriya kunye nokubumba, kwaye isetyenziswa ngokubanzi ekungcoleni kweeseli kwiinkalo zebhayoloji kunye neyeza.
4. I-Redox: I-Benzo-2-naphthol yi-agent yokunciphisa enamandla enokuthi i-oxidize nge-oxygen phantsi kweemeko ezifanelekileyo. Inokuthi ifakwe kwi-oxidized kwi-azo compounds yi-oxidants.
Ngokuqhelekileyo, i-benzoazo-2-naphthol yinto ebalulekileyo ye-organic compound ngenxa yeempawu zayo ezintle zedayi kunye neendawo ezibanzi zokusebenzisa.
Ukusetyenziswa kunye neendlela zokudibanisa
I-Benzo-2-naphthol yidayi ye-fluorescent ye-organic enoluhlu olubanzi lwezicelo kuphando lwezekhemikhali kunye ne-biological science.
Indlela yokudibanisa ye-benzoazo-2-naphthol idla ngokuqhutywa ngala manyathelo alandelayo:
1. I-Aniline isabela nge-nitrosohydroxylamine salts (eyenziwe phantsi kweemeko ze-acidic) kumaqondo okushisa aphantsi ukwenza i-azo compounds.
Isiphumo se-azo compound emva koko sisabela nge-2-naphthol phantsi kweemeko ze-alkali ukuvelisa i-benzoazo-2-naphthol.
I-Benzoazo-2-naphthol ineendlela ezahlukeneyo zokusetyenziswa kwizicelo eziphathekayo, kuquka:
1. Izinto zeLuminescent: I-Benzo-2-naphthol ineempawu ezintle ze-fluorescence kwaye ingasetyenziselwa ukulungisa izinto ezikhanyayo, ezifana ne-organic light-emitting diodes (OLEDs) kunye neeseli zelanga eziphilayo.
2. Izixhobo zokubonisa: I-Benzo-2-naphthol ingasetyenziswa ekulungiseleleni i-organic thin-film transistors (OTFTs), ezibonisa izixhobo ezinokuhamba kwe-electron ephezulu kunye nokuguquguquka.
3. I-Biomarkers: Iimpawu ze-fluorescent ze-benzoazo-2-naphthol zenza ukuba kube yinto efanelekileyo yokukhetha i-biomarkers, enokusetyenziswa kuphando lwezinto eziphilayo ezifana ne-cell imaging, i-molecular probes, njl.
Ulwazi ngoKhuseleko
I-Benzoazo-2-naphthol yi-organic compound eyaziwa ngokuba yi-PAN. Nantsi intshayelelo yolwazi lwayo lokhuseleko:
1. Ubuthi: I-Benzo-2-naphthol inobuthi obuthile kumzimba womntu kwaye ingaba nemiphumo ephazamisayo kunye nokonakalisa ulusu, amehlo kunye nenkqubo yokuphefumula. Ukuba sesichengeni ixesha elide okanye ukuba sesichengeni esinzima kunokukhokelela kwiingxaki zempilo ezingapheliyo.
2. I-Inhalation: Uthuli okanye umphunga we-benzoazo-2-naphthol unokuthatyathwa ngumzila wokuphefumula, obangela ukucaphuka kokuphefumula, ukukhwehlela, ukuphefumula okufutshane kunye nezinye iimpawu. Ukuphefumla kakhulu kunokubangela umonakalo emiphungeni.
4. Ukungena: I-Benzo-2-naphthol ayifanele ifakwe, enokubangela ukuphazamiseka kwesisu, ukuhlanza, isifo sohudo kunye nezinye iimpawu. Kwimeko yokungeniswa ngengozi, funa unyango ngokukhawuleza.
5. Indalo engqongileyo: I-Benzo-2-naphthol ineengozi ezithile ezinokubakho kwindalo, ngoko ke kuyimfuneko ukuthobela ingqalelo ukuyithintela ekungeneni kwimithombo yamanzi kunye nomhlaba, kwaye ihambelane nemimiselo yokukhusela indalo xa usebenzisa kwaye uyilahla.
6. Ukugcinwa kunye nokuphatha: I-Benzo-2-naphthol kufuneka igcinwe kwindawo eyomileyo, epholileyo, enomoya, kude nemithombo yomlilo kunye nezinto ezinokutsha. Izikhongozeli kufuneka zilahlwe ngokufanelekileyo emva kokusetyenziswa.
