Aqueous acrylamide solution, stabilizer for aqueous acrylamide solution, and stabilization method for aqueous acrylamide solution

摘要

There is provided an aqueous acrylamide solution including 2,2,6,6-tetramethylpiperidine 1-oxyl in the ratio of 2 to 100 mg and manganese ions in the ratio of 0.2 to 2.0 mg per 1 kg of acrylamide. According to the present invention, an aqueous acrylamide solution having favorable quality and high stability with suppressed polymerization of acrylamide, a stabilizer used therefore, and a stabilization method can be provided.
