Caprolactam is a key building block in the production of nylon. During the manufacturing process, various impurities can be formed or introduced, including cyclohexanone, epsilon-caprolactone, and lactams. These impurities can affect the quality and performance of the final nylon product, and must be carefully controlled and minimized to ensure optimal production outcomes. Advanced analytical techniques are often used to identify and quantify caprolactam impurities.
