Autoxidation of alkyd resins catalyzed by iron(II) bispidine complex: Drying performance and in-depth infrared study

Abstract

A new iron(II) bispidine complex with increased solubility in various organic solvents has been prepared and characterized by the spectroscopic methods and the X-ray crystallography. In-depth infrared study together with mechanical tests demonstrated the excellent catalytic performance of the iron compound in autoxidation process and established it as the potent drier suitable for solvent-borne alkyd binders. This study further reports the 2D-correlation analysis of the time-resolved infrared spectra, which was used for the first time for detailed analysis of the autoxidation process mechanism.
