Abstract
Photobleaching of eosine in methanol, ethanol, isopropanol and n-butanol in vacuo was investigated and it was concluded that the primary process is the dehydrogenation of alcohols by the metastable excited eosine molecule. In the presence of oxygen, the photobleaching is suppressed completely, but the sensitized photoöxidation of alcohol takes place.Keywords
