Kinetics of catalyzed hydrolysis of hydrazine hydrate by acetone azine

With self-made acetone azine and distilled water as raw materials,the different process conditions of acetone azine and water to hydrazine hydrate were studied in the presence of catalyst.The influence of catalyst,catalyst dosage,mole ratio of acetone azine to water,temperature on the hydrolysis reaction is investigated.The optimal process conditions obtained are as follows: C106 weak-acid ion exchange resin was selected as catalyst,the mass fraction of catalyst is 5%,molar ratio of water to acetone azine is 7 ∶ 1,and temperature is 90 ℃.In this condition,the conversion of acetone azine is 34.6%.On that basis,a power-law function kinetic model was used to describe the macrokinetics of the reaction of acetone azine.The results show that the apparent activation energy and pre-exponential factor of forward reaction are 2 067.57 J/mol and 5.957 8,respectively;the apparent activation energy and pre-exponential factor of the reverse reaction are 125.07 J/mol and 4.146 3,respectively;the reaction orders with respect to acetone azine,water,hydrazine hydrate and acetone are 0.099 8,0.110 8,0.113 2 and 0.114 5.
