Abstract
Abstract In producing chemiluminescence by the reaction of bis(6-carbopentoxy-2,4,5-trichlorophenyl)oxalate with a peroxide in presence of 9,10-bis(phenylethynyl)anthracene the initial luminosity on mixing these reaction components in a suitable diluent is increased by using the specific concentration of bis-oxalate ester component in the range from 0.05 to 0.09 mole per liter in the reaction mixture.
