Abstract: The direct hydration of olefins to corresponding alkanols is of significant importance in both the theoretical and industrial areas.In view of the hydration of 1-C12 olefin to 2-C12 alkanol, research is performed on the preparation and screening of the catalysts as well as the influence of reaction parameters.It is found among various catalysts, the amphiphilic phosphotungstic acid-supported β zeolite catalyst behaves the best, over which the single pass yield and selectivity of dodecanol achieve 5.5% and 100%, respectively under optimized reaction conditions.
