ActiveTest methods of caprolactam for industrial use - Part 7: Determination of iron content
工业用己内酰胺试验方法 第7部分：铁含量的测定
Application Summary AI generated
This standard specifies a spectrophotometric method for determining trace iron content in caprolactam used in industrial production. It is applied in quality control laboratories within the chemical industry, particularly for manufacturers and users of caprolactam, which is a key monomer for producing nylon-6 fibers and engineering plastics. The test ensures that iron impurities remain within acceptable limits to prevent discoloration or degradation during polymerization processes.
