Filed: 2000-03-28
Abstract: PROBLEM TO BE SOLVED: To provide a method of easily producing a fluorescence marked polycarboxylic acid with a little change of the fluorescence intensity by outside factors (such as pH and coexisting ions). SOLUTION: A method includes introducing an organic fluorescent group into a polycarboxylic acid through the following three reacting processes; (1) reacting the polycarboxylic acid with a specific disulfide group-containing a diamine compound, (2) reducing the disulfide group introduced into the polycarboxylic acid to generate a mercapto group, and (3) reacting an organic compound including an organic fluorophore having reactivity with a mercapto group, with the polycarboxylic acid into which the mercapto group was introduced. Then the obtained fluorescence marked polycarboxylic acid is preferably used as a water treatment additive showing a function such as a scale inhibition and a sludge dispersion, in various water systems such as s cooling water system and a boiler water system, and its concentration is controlled easily by a fluorescence analysis.
