SURFACTANT-CONTAINING AMIDE COMPOUND SOLUTION
The present invention relates to an amide compound solution comprising an amide compound and a surfactant. More specifically, the invention relates to an amide compound solution comprising amide compound, and 2.7˜20 mg of a cationic surfactant per 1 kg of the amide compound or 0.01˜10 mg of a C15˜C20 carboxylic acid or its salt as an anionic surfactant per 1 kg of the amide compound. The present invention provides an amide compound solution which is manufactured using a biocatalyst and which has a low level of foaming, and thereby improving the operability and yield when manufacturing an amide compound-based polymer.
