为了得到丁酮连氮高压非催化水解制水合肼的反应动力学方程，在间歇釜式反应器中对其水解过程进行了研究．探讨了转速、压力、丁酮连氮与水的物质的量之比、温度和时间对丁酮连氮水解率的影响．研究了433．15—463．15K温度范围内丁酮连氮水解制肼的非催化反应本征动力学，得到丁酮连氮水解的拟均相可逆非线性动力学方程．结果表明：丁酮连氮水解制肼正反应的活化能为15214．16J／mol，指前因子为3．2033L／（mol．h）；其逆反应的活化能为46．73J／mol。指前因子为0．04911L／（mol·h）；丁酮连氮、水、水合肼、丁酮的反应级数分别是0．01073，0。1567，0．8484，0．9275．

In order to obtain kinetics equation of synthesis ofhydrazine hydrate by methyl ethyl ketazine high pressure and non-catalyzed hydrolysis as well study it＇s hydrolysis in a batch reactor, The influence of speeds, pressure, mole ratio of methyl ethyl ketazino to water, temperatures and times were studied, The intrinsic kinetics of non-catalytic reaction of methyl ethyl ketone is studied and the reversible nonlinear equation of433,15 g to 463,15 g is abtained, The results show that the aparent activation energy and proexponential factor of forward reaction are 15 214,16 J/reel and 3,203 3 L/（mol.h）, the apparent activation ener~ and pre-exponential factor of the reverse reaction are 46,73 J/reel and 0,049 11 L/（mol,h）; the re- action order with respect to methyl ethyl kotazine, water, hydraztne hydrate and methyl ethyl ketone are respectively 0,010731, 0,1567, 0,8484, 0,9275,
