Hexamine as an experimental rocketry propellant

Today I started to experiment with hexamine and KNO3 as an experimental rocketry propellant, but whatever mixture ratio I used the mixture was unable to combust. I thought maybe the KNO3 is too wet so I dehydrated it, but the result was the same. Ok, the only possibility was that they chemcial store sold me something else than KNO3. The container was sealed and the chemical symbol right, but who knows in China... I made a aqueous solution of the salt and electrolyzed it. Odor of chlorine...So my KNO3 is probably NaCl or KaCl.
