摘要：

Experiments performed at 433 K and 453 K with 1-pentanol/water and 1-pentanol/DNPE (di-n-pentyl ether) clearly states the inhibiting effect of water released in the liquid-phase dehydration of 1-pentanol to DNPE on ion-exchange resin. The inhibiting effect of water was described by an empirical correction factor in the Eley-Rideal rate model deduced in a previous work. Best results were obtained with a factor including a Freundlich-like adsorption isotherm expression. The activation energy of dehydration reaction lowers slightly on splitting off the water effect, and it is 114.0 +/- 0.1 kJ/mol.
