EVIDENCE FOR "PSEUDO-LIQUID PHASE" IN THE DEHYDRATION OF ISOPROPANOL OVER H3PW12O40

Article abstract of DOI:10.1246/cl.1983.573

Transient response method using isotopically labeled isopropanol was applied to confirm the "pseudo-liquid phase" behavior of the dehydration of isopropanol over H3PW12O40.Results were treated by moment analysis.Under the stationary state of catalytic reaction at 80-90 deg C, a large amount of isopropanol was present in the bulk and the absorption-desorption process of isopropanol in the whole bulk was much more rapid than its dehydration to propene, demonstrating the "pseudo-liquid phase" behavior.
