In this paper various runaway criteria for batch reactors (BRs) and semi-batch reactors (SBRs) have been used and compared to study the boundaries of different thermal behaviors for the acetic anhydride hydrolysis reaction with the solvent of acetic acid carried out in BRs and SBRs. It is shown that the majority of criteria for BRs could give relatively precise results, but the remaining minority are less accurate due to they all have some specific assumptions. Besides, the simulated results indicated that all the criteria for SBRs could accurately identify the transition point from TR to QFS behaviors in spite of that they give slight different results of transition point corresponding to NI and TR behaviors. The results can give an effective instruction for selection and usage of runaway criteria, especially in terms of effectiveness and applicability, to easily identify thermal behaviors in chemical industry.

在本文中，使用了间歇式反应器 (BR) 和半间歇式反应器 (SBR) 的各种失控标准并进行了比较，以研究乙酸酐水解反应的不同热行为的边界在BRs和SBRs中以乙酸为溶剂进行。结果表明，大多数 BR 标准可以给出相对精确的结果，但其余的少数标准由于都有一些特定的假设而不太准确。此外，模拟结果表明，所有 SBR 标准都可以准确识别从 TR 到 QFS 行为的转变点，尽管它们给出的转变点对应于 NI 和 TR 行为的结果略有不同。结果可以为失控标准的选择和使用提供有效的指导，特别是在有效性和适用性方面，以轻松识别化学工业中的热行为。
