Product of a nitrosation.
The greenish-blue color is caused by the generated dinitrogen-dioxide what was a side product of the reaction. Since nitrous gases are not so good for our health, argon is bubbled through the solution to eliminate the nitrous fumes (mainly nitrogen dioxide) from the reaction mixture.
