This study describes the catalytic performance of an iron(III) complex bearing a phthalocyaninato-like ligand in two solvent-borne and two high-solid alkyd binders. Standardized mechanical tests revealed strong activity, which appeared in particular cases at concentrations about one order of magnitude lower than in the case of cobalt(II) 2-ethylhexanoate, widespread used in paint-producing industry. The effect of the iron(III) compound on autoxidation process, responsible for alkyd curing, was quantified by kinetic measurements by time-resolved infrared spectroscopy and compared with several primary driers. Effect of the drier concentration on coloration of transparent coatings was determined by UV-Vis spectroscopy.
本研究描述了一种带有类酞菁配体的铁（III）配合物在两种溶剂型和两种高固体醇酸树脂粘合剂中的催化性能。标准化机械测试显示出很强的活性，在某些特定情况下，其浓度比油漆生产行业广泛使用的2-乙基己酸钴（II）低约一个数量级时仍有此活性。通过时间分辨红外光谱进行动力学测量，对铁（III）化合物对醇酸树脂固化所涉及的自氧化过程的影响进行了量化，并与几种主要催干剂进行了比较。通过紫外-可见光谱法测定了催干剂浓度对透明涂层着色的影响。
