在２９８．６Ｋ～３１８．２Ｋ温度范围内，研究了磁场对乙酸乙酯皂化反应速率常数的影响。结果表明，在磁场条件下，反应速率常数明显增大；反应的活化焓与活化熵分别降低１１．８６ｋＪ·ｍｏｌ－１和３４．３３Ｊ·ｍｏｌ－１Ｋ－１。对磁场影响乙酸乙酯皂化反应速率的原因进行了分析讨论
The effect of magnetic field on the rate constant of ethyl acetate saponification reaction was studied in the temperature range of 298.6K ~ 318.2K. The results showed that the reaction rate constant increased significantly under magnetic field conditions. The activation enthalpy and activation entropy decreased by 11.86 kJ · mol-1 and 34.33 J · mol-1K-1, respectively. The reason of the influence of magnetic field on the rate of saponification of ethyl acetate was discussed and discussed
