Abstract
Abstract Fluorescent brighteners based on dicarboxylic acid derivatives are compounds of the benzoxazole type, synthesized by a simple reaction using polyphosphoric acid. The obtained compounds ( 4a – c , 6a – c , 8a – c ) were characterized by the analysis of proton NMR spectrum and confirmed by UV spectrum. The physical properties of the compounds ( 4a – c , 6a – c , 8a – c ) were performed by fastness test and whiteness measurement.
