Qhov sib txawv tseem ceeb ntawm anthracene thiab phenanthrene yog tias anthracene tsis ruaj khov piv rau phenanthrene.
Anthracene thiab phenanthrene yog cov qauv isomers. Lawv muaj tib yam tshuaj formula, tab sis cov qauv ntawm cov molecule txawv ntawm ib leeg. Txawm li cas los xij, ob lub tebchaw no muaj peb lub nplhaib benzene ib molecule.
YAnthracene yog dab tsi?
Anthracene yog ib qho khoom sib xyaw uas muaj peb lub nplhaib benzene nyob rau hauv ib txoj hlua ncaj. Cov tshuaj formula yog C14H10 Nws tshwm li cov khoom tsis muaj xim, thiab nws muaj ntxhiab tsw tsw. Tsis tas li ntawd, cov qauv tshuaj ntawm anthracene tsis ruaj khov vim tsis muaj pi bonding.
Daim duab 01: Cov qauv ntawm Anthracene
Qhov loj ntawm anthracene yog thee tar. Nws muaj li ntawm 1.5% anthracene. Tsis tas li ntawd, cov impurities uas peb tuaj yeem pom hauv anthracene yog phenanthrene thiab carbazole. Peb tuaj yeem tsim cov khoom siv no hauv chav kuaj los ntawm cyclodehydration ntawm O-methyl hloov pauv diaryl ketones. Ntxiv mus, qhov sib xyaw no tuaj yeem ua rau photodimerization nyob rau hauv UV teeb. Peb hu qhov no dimer dianthracene.
Kev siv loj ntawm anthracene yog tsim cov xim liab alizarin. Tsis tas li ntawd, muaj qee qhov dyes uas peb tuaj yeem tsim siv cov khoom sib xyaw no. Tsis tas li ntawd, nws yog ib qho tseem ceeb raws li ib tug scintillator nyob rau hauv detectors rau siab zog protons. Tsis tas li ntawd, zoo li ntau lwm yam polycyclic aromatic hydrocarbons, anthracene kuj muaj nyob rau hauv cov pa luam yeeb.
YPhenanthrene yog dab tsi?
Phenanthrene yog polycyclic aromatic hydrocarbon muaj peb fused benzene rings nyob rau hauv ib tug non-linear qauv. Lub npe phenanthrene yog kev sib xyaw ntawm phenyl thiab anthracene. Nws yog cov khoom tsis muaj xim thiab ua rau khaus.
Daim duab 02: Tus qauv ntawm Phenanthrene
Ntxiv mus, cov tshuaj no yuav luag insoluble hauv dej tab sis soluble nyob rau hauv tsawg polar solvents xws li toluene. Peb tuaj yeem pom cov khoom no hauv nws daim ntawv ntshiab hauv cov pa luam yeeb. Tsis tas li ntawd, nws muaj txiaj ntsig zoo hauv kev ua dyes, plastics, tshuaj tua kab, tawg, tshuaj, thiab lwm yam.
Dab tsi zoo sib xws ntawm Anthracene thiab Phenanthrene?
- Anthracene thiab phenanthrene yog cov qauv isomers.
- Ntxiv mus, ob lub tebchaw no muaj peb lub nplhaib benzene ib molecule.
Qhov txawv ntawm Anthracene thiab Phenanthrene yog dab tsi?
