Study on the Reaction Between Methyl Hydrazine and Formaldehyde in Nitric Acid Medium

摘要

正To make sure whether the reaction between formaldehyde and methyl hydrazine (MMH) could happen in dilute nitric acid solution, the condensation reaction between the two ones was investigated at 16 ℃. The reaction was slow and it took over 5 hours to reach the balance and the solution turned yellow at last. The maximum absorption peaks of the product existed at 340 nm and 400-450 nm, respectively.
