  Iron contaminants are associated with a beta-dicarbonyl in an isocyanate composition that includes polymeric methylene diphenyl diisocyanate (PMDI). The association of the iron contaminant and the beta-dicarbonyl is thought to minimize a catalytic effect of the iron contaminant when the isocyanate composition is reacted with a polyol to form a polyurethane. The iron contaminant is associated with the beta-dicarbonyl in a method that includes the step of providing the isocyanate composition and the step of combining the beta-dicarbonyl and the isocyanate composition. The isocyanate composition is included in a polyurethane system and typically includes the association product of the iron contaminant and the beta-dicarbonyl.
