• 中文摘要： 磷酸鉻觸媒上之異丙醇脫水反應動力研究係在一連續式微反應上進行實驗, 反應溫度為423-573K。反應主要產物(>99%)為丙烯和水, 幾乎沒有其它產物產生, 反應對異丙醇之分壓為一階反應, 反應可以用Langmuir-Hinshelwood模式來描述, 而其速率限制步驟為吸附態異丙醇之表面反應步驟。
• 英文摘要： The dehydration of isopropyl alcohol, IPA, over the chrominophosphate catalysts was studied by a continuous flow micro-reactor in the temperature range of 423-573K. The reaction is very specific with greater than 99% conversions to propylene and water. The reaction Kinetics is first order with respect to the partial pressure of IPA. The reaction mechanism can be described by the Langmuir- Hinshelwood model and the corresponding rate determining step can be justified by the surface reaction of adsorbed IPA on the active sites of the catalyst surface.
