New metal ion control agents based on dicyclopentadiene derivatives
摘要:
New compounds have been prepared from dicyclopentadiene bis(methylamine) which have the following formula

wherein substituents A, B, X and Y each are independently selected from radicals comprising hydrogen, C 2 to C 6 hydroxyalkyl; hydroxyethyl- and hydroxypropylsulfonic; meth- yienephosphonic; methylene-, ethylene- and propylenesul- fonic, C 2 to C 4 alkylcarboxylic acid radicals; and the alkali metal, alkaline earth metal, ammonia, and amine salts of the foregoing acids; and wherein at least one of A, B, X, and Y is other than hydrogen. These compounds are useful as ion control (chelating) agents in aqueous solutions. In a preferred embodiment, the compounds have threshhold (less than stochiometric amounts required) activity.
