Paper Title:
Preparation and Catalytic Performances of Glucose Char Sulfonic Acids
  Abstract

A series of glucose char sulfonic acids (GCSA) were prepared via a two-step procedure involving sulfuric acid catalytic charring of glucose and successively sulfonation. GCSA prepared in this new route possess high sulfonic acid loading, and acid capacity of GCSA-2 reaches as high as 2.60 mmol g-1 at charring conditions of sulfuric acid being 80%, ratio of glucose and sulfuric acid being 1:8, charring time being 3 h, charring temperature being 80 °C. All GCSA were found to be active in the esterification between n-butanol and acetic acid. GCSA-2 behaved with good activity with 95.6% conversion and 100% ester selectivity.
