Michael B. Mooiman has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Ion exchange extraction of metallic and non-metallic anions by control of the basicity of amine extractants
    Patent number: 4774003
    Abstract: Amine extractants useful in extracting metallic anions are modified with Lewis bases, having substantial organic solubility, such as tributyl phosphate, to improve the extraction capability of such amines. Generally, addition of Lewis bases to weakly basic amines increases the basicity of such amines.
    Type: Grant
