ABSTRACT:
This invention relates to a composition comprising (a) epsilon caprolactam acid or salt or amide, acid or salt or amide, 5-amino-4-methylpentanamide, 5-amino-4-methyl-1-pentanol, 5-imino-2-methyl-1-pentanamine, 5-amino-2-methyl-1-pentanol, 5-imino-4-methyl-1-pentanamine and 2-butyl-4,5-dipropylpyridine, wherein the weight ratio of component (a) to component (b) is at least about 99 to 1. The epsilon caprolactam compositions are useful in the preparation of nylon 6.
