【Abstract】 Preparation of tertiary amyl alcohol from hydration of isoamylene enriched C 5 fraction was carried in the laboratory. The effects of catalyst, reaction temperature, pressure, space velocity and water/isoamylene ratio were investigated. The test result showed that at the reaction conditions of a pressure range of 0.3～0.6 MPa, a temperature of 65 ℃, a space velocity of 0.6 h -1 , and a water to amylene ratio of 5, the isoamylene conversion was 48.6% and the tertiary amyl alcohol selectivity was 92.2%. The catalyst life was more than 1 000 h. The laboratory result was repeated in a 100 ml pilot plant.更多还原
