Ammonia solution is, of course, alkaline. The reaction will take 10 - 180 minutes depending on reaction temperature, pH, and H2O2 charge. With moderate temperatures (< 40 deg C) and a pH of 10 - 11, the H2O2 demand should be about 0.8 parts H2O2 per part HCHO, which translates into an H2O2 cost of about $0.75 USD per lb-HCHO.
