F-5731 CATALYST PRETREATMENT FOR OLEFIN HYDRATION Abstract Process for production of alcohol or ether by hydration of olefinic feedstock containing at least one lower alkene by contacting the olefinic feedstock and water in a hydration zone with porous solid metal oxide acidic olefin hydration catalyst under olefins hydration conditions, characterized by pretreating porous solid catalyst, such as acid zeolite, prior to contacting with the olefinic feedstock with a wetting agent containing at least one polar aliphatic oxygenated hydrocarbon to substantially wet the solid catalyst and sorb the wetting agent into pores of the solid catalyst. After initiating hydration reaction by feeding the olefinic feedstock and water, increased catalytic activity is obtained. The process is particularly useful for making isopropanol and DIPE from propylene and water.
