Abstract:
1. A method for producing a carboxamide derivative comprising: synthesizing a carboxamide by reacting, no presence a catalyst, a fatty acid ester represented by General Formula (1) below with a diamine represented by General Formula (2) below at a molar ratio of the diamine to the fatty acid ester of 1.20 to 1.60; and producing a carboxamide derivative by reacting the carboxamide and hydrogen peroxide, wherein the carboxamide comprises 0.02% by weight to 0.18% by weight of amide ester represented by General Formula (3) below; and the carboxamide derivative is represented by General Formula (4) below: wherein, in General Formula (1) above, R wherein, in General Formula (2) above, R wherein, in General Formula (3) above, R wherein, in General Formula (4), R
