Qhov sib txawv tseem ceeb ntawm auxochrome thiab chromophore yog an auxochrome yog ib pawg ntawm atoms uas hloov cov qauv ntawm chromophore, whereas chromophore yog moiety moiety uas muab cov xim. ntawm molecule. Chromophores tuaj yeem tso saib xim thaum nws raug pom lub teeb.
Qhov txawv ntawm chromophore thiab auxochrome yog dab tsi?
Chromophore yog ib feem ntawm cov molecule uas thaum pom lub teeb pom kev yuav nqus thiab cuam tshuam qee yam xim. Auxochrome yog ib pawg ntawm cov atoms uas ua haujlwm tau zoo thiab muaj peev xwm hloov pauv lub peev xwm ntawm chromophore los cuam tshuam cov ximAzobenzene yog ib qho piv txwv ntawm cov xim uas muaj chromophore.
Chromophore thiab auxochrome piv txwv yog dab tsi?
Txoj kev cuam tshuam ntawm chromophore
Piv txwv li, benzene tsis pom xim vim nws tsis muaj chromophore; Tab sis nitrobenzene yog xim daj daj vim muaj cov pab pawg nitro (−NO2) uas ua raws li chromophore. Tab sis p-hydroxynitrobenzene nthuav tawm cov xim daj sib sib zog nqus, uas cov pab pawg - OH ua raws li auxochrome
piv txwv auxochrome yog dab tsi?
Ib feem ntawm cov molecule, piv txwv li radical lossis ionic functional pawg, uas txhim kho cov xim ntawm chromophore hauv cov xim organic. Auxochromes kuj tseem tuaj yeem muab qhov chaw ionic uas ua rau cov zas zas khi rau cov fiber ntau. Piv txwv ntawm pawg auxochrome yog - COOH, -SO3H, -OH, thiab -NH3.
hom chromophore yog dab tsi?
Molecules uas nqus lub teeb hu ua chromophores. Muaj ob hom choromphores loj: kev hloov hluav taws xob . kev hloov pauv hloov pauv.
