A method of making a pyranine monomer composition comprises the step of reacting pyranine with a functionalizing agent that functionalizes the pyranine molecule with a polymerizable functional group to provide a composition of functionalized pyranine monomers, said functionalization reaction taking place in an aqueous reaction medium, and in the presence of a molar excess of said functionalizing agent, such that the functionalization reaction product is a monomer composition substantially free of unfunctionalized pyranine compound. The pyranine monomer compositions made by the method can be used to make fluorescent tagged water soluble polymer compositions that advantageously are substantially free of unpolymerized pyranine. The fluorescent tagged water soluble polymer compositions can be used in a method of inhibiting scale in industrial water systems.

The present invention relates to a system and method for continuous monitoring of system health in closed water systems. Sensors are provided to measure a plurality of system parameters.

Furthermore, a method is describe using a pump to deliver the water to the device in connection with a control solution.

Disclosed herein are phosphoester anticorrosion compositions comprising an adduct of an alkylphenol ethoxylate phosphate ester with 1,3,5,7-tetraazaadamantane. The adducts are storage stable neat or in a solvent. The adducts are suitably added at about 0.5 ppm to 500 ppm by weight or by volume to a water source comprising one or more corrodents to inhibit corrosion of metal surfaces contacting the water source. The phosphoester anticorrosion compositions are as effective or more effective at inhibiting corrosion than conventional sulfur-based corrosion inhibitors when compared on a weight or volume basis.
