Abstract

Using n-butenes and water as feedstocks and molecular sieves as catalysts, effects of the reaction temperature, the reaction pressure, the weight hour space velocity (WHSV), and the ratio of water to n-butenes on the conversion of n-butenes were studied. The experimental results showed that the optimal reaction temperature, the pressure, the WHSV, and the ratio of water to n-butenes were 180 °C, 8.0 MPa, 0.2 h-1 , and 8, respectively; the single conversion of n-butenes and the selectivity of 2-butanol formation were found to be 35.52% and 99%, respectively.

Key words: sec-butanol; molecular sieve; synthesis; n-butenes; reaction condition
