Abstract
Provided are [1] a xylylenediamine composition containing xylylenediamine and a compound represented by the following general formula (1), wherein the content of the compound represented by the general formula (1) is 0.001 to 0.1 parts by mass based on 100 parts by mass of the xylylenediamine; and a method for producing a polyamide resin including the steps of introducing a compound represented by the following general formula (1), a diamine including xylylenediamine (but excluding the compound represented by the general formula (1)), and a dicarboxylic acid into a reaction system and performing a polycondensation reaction, wherein the amount of the compound represented by the general formula (1) to be introduced is 0.001 to 0.1 parts by mass based on 100 parts by mass of the xylylenediamine, where, in the general formula (1), n and m each independently represent an integer of 0 to 6, excluding the case where n and m are both 1.
