摘要:
The present invention relates to a high purity lactam comprising impurities having a cyclic bridge structure in 50 ppm by weight or less and a method for producing the same. The present invention is characterized in that a content of impurities having a cyclic bridge structure is controlled by using a cycloalkanone purified by recrystallization.
