Modified Methods for the Synthesis of Triazinyl Fluorescent Brightener Intermediates

Modified Methods for the Synthesis of Triazinyl Fluorescent Brightener Intermediates

The production of triazinyl fluorescent brightener intermediates in high yields is described. The method involves a simplified work-up for the preparation of 4-nitro-toluene-2-sulfonic acid and the use of diethylene glycol instead of water in the preparation of 4,4'-dinitrostilbene-2,2'-di...
