Claims6
A polyimine triglyceride composition having has 8 to 16 nitrogen moieties per triglyceride unit.
A method for making a polyimine triglyceride, said method comprising providing a polyketone vegetable oil triglyceride having 8 to 16 ketone moieties per triglyceride unit, and reacting said ketone moieties with a primary amine moiety to form a polyimine adduct;
- wherein said method utilizes a non-aqueous solvent.
A method to remove metal species from a material suspected of containing one or more metal ion species, said method comprising contacting said material with a polyimine triglyceride having has 8 to 16 nitrogen moieties per triglyceride unit for a period of time and under conditions effective for sequestering said metal species by said polyamine triglyceride thereof, and separating said polyimine triglyceride from said material.
