The synthesis of iminodisuccinic acid (IDS) from fumaric acid and ammonium bicarbonate in methanol instead of water is a fascinating modification! Here's a breakdown of key considerations:
Solvent Effects: Methanol is a less polar solvent than water. This can impact reaction rates, solubility of reactants, and product formation.
Reaction Mechanism: The reaction mechanism for IDS synthesis likely involves nucleophilic attack of the ammonium bicarbonate on the fumaric acid, followed by cyclization and subsequent reactions.
Analysis: You'd likely need to analyze the reaction mixture using techniques like NMR spectroscopy (to identify product formation and characterize the structure), HPLC (for purity determination), and potentially mass spectrometry (for molecular weight confirmation).
