Abstract
Micro-distillation is one of the unit operation technologies that are looking toward innovation through on-site and on-demand production system. In this study, a simple structure microdistillator consisting of some plates was applied to reactive distillation, and its potential was investigated. As a target reaction, the heterogeneous esterification between acetic acid and methanol using a solid acid catalyst was employed. The effects of feedstock supply rate, feedstock composition, and device temperature on operation stability and conversion were examined. By controlling the feedstock supply rate and temperature properly, a stable operation with a conversion of approximately 100% was successfully achieved. The amount of methyl acetate produced per weight of catalyst was greater in the reactive distillation using a microdistillator than in the batch reaction, soon after the start of the reaction. Thus, it was demonstrated that the reactive distillation using a microdistillator was able to achieve highly efficient reactions with short reaction time and small amounts of catalyst.
