During the distillation process, the bottom product of one column mainly contains these two substances along with the heavy components. During the degassing process in the two towers, acetic acid appeared at the top of the towers again. Does anyone know what’s going on? Are there any good ways to suppress decomposition?
It is recommended to study the factors affecting the thermosensitivity of the substance and their intensity, as well as whether residual catalyst has an impact If temperature sensitivity is a concern, vacuum distillation or film evaporation can be used for separation
