研究了连续流搅拌釜式反应器（CSTR）酸催化缩水甘油水解反应的安全操作极限。通过动态建模进行稳定性分析。所得结果与公开文献中报道的实验数据进行了比较。为此，引入了无量纲变量和参数，并定义了不稳定的物质和能量平衡。系统方程使用Matlab（Matlab®软件）求解。因此，绘制了分叉图（一维和二维）。所有不同的动态状态进行了识别和研究（热稳定性和不稳定性，唯一和多个解决方案;霍普夫分叉;转折点和包络的周期性解决方案）。最后，确定了酸催化缩水甘油水合反应的固有热不稳定性和循环行为。找到了保证CSTR安全运行的合适条件。© 2016美国化学工程师学会AIChE J，62：4418-4426，2016
The aim of this work was to determine the limits of safe operation of continuous flow stirred-tank reactor (CSTR) for the acid-catalyzed hydrolysis of glycidol. The stability analysis was performed by dynamic modelling. The obtained results were compared with the experimental data reported in the open literature. For this purpose, dimensionless variables and parameters were introduced and unstable material and energy balances were defined. The system equations were solved using Matcont (Matlab® software). Thus, bifurcation diagrams (in one and two dimensions) were mapped. All different dynamic states were identified and studied (thermal stability and instability, with unique and multiple solutions; Hopf bifurcations; turning points and envelope of periodic solutions). Finally, the intrinsic thermal unstable and cycle behavior of the acid-catalyzed hydration of glycidol to produce glycerol was identified. The appropriate conditions to guarantee safe operation of CSTR were found. © 2016 American Institute of Chemical Engineers AIChE J, 62: 4418–4426, 2016
