| titleOfInvention | Method for producing polyamide 6 |
| abstract | An object of the present invention is to provide a method for producing polyamide 6 with a short time, high efficiency, and a small amount of impurities, in which a hot water extraction step for removing impurities can be shortened or omitted. SOLUTION: The method for producing polyamide 6 using at least one polymerization apparatus, comprising: a polymerization apparatus (polymerization apparatus (A)) located at the most upstream position of a mixture containing 20 to 40% by weight of aminocaproic acid (mixture (X)). ), Wherein the content of the cyclic oligomer of the dimer to tetramer is 0.5% by weight or less in the polyamide 6, which is taken out at the outlet of the most downstream polymerization apparatus.
