Titanate nanotubes-bonded organosulfonic acid as solid acid catalyst for synthesis of butyl levulinate. Issue 7 (18th January 2018) - Zhou, Shuolin
Abstract : TiO2 nanotubes-bonded organosulfonic acid as a hybrid catalyst exhibited better activity and good reusability for esterification reaction. Abstract : In this study, titanate nanotubes-bonded organosulfonic acid (TNTs–SO3 H) was prepared and employed as an efficient heterogeneous catalyst for esterification of levulinic acid with n -butanol. Two reaction products pseudo n -butyl levulinate (pseudo-BL) and n -butyl levulinate (BL) were detected by GC-MS. The catalyst showed 86.8% conversion of levulinic acid with 99.7% selectivity towards n -butyl levulinate. TNTs–SO3 H exhibited strong acidic sites and high stability even after seven cycles of usage and would be well expected to be a potential candidate for alkyl levulinate production.
