Glucose Isomerization Using Alkali Metal and Alkaline Earth Metal Titanates

摘要

Abstract > Glucose isomerization was performed using various titanate catalysts, which include SrTiO <sub>3</sub> , BaTiO <sub>3</sub> , CaTiO <sub>3</sub> , Na <sub>2</sub> Ti <sub>6</sub> O <sub>13</sub> , K <sub>2</sub> Ti <sub>6</sub> O <sub>13</sub> , and Sr <sub>3</sub> Ti <sub>2</sub> O <sub>7</sub> , prepared using a conventional solid‐phase method. Among the titanates, SrTiO <sub>3</sub> , CaTiO <sub>3</sub> , and Na <sub>2</sub> Ti <sub>6</sub> O <sub>13</sub> offered a relatively high fructose yield (32?%) with a high selectivity (68–78?%). The yields are comparable to yields reported previously using a Sn‐modified BEA zeolite, which shows a high efficiency for glucose isomerization as a Lewis acid catalyst. A study of the mechanism of glucose isomerization on a SrTiO <sub>3</sub> catalyst surface by using 1 H?NMR spectroscopy suggested that the titanates catalyze the isomerization as base catalysts. Thus, the effect of the basicity of the titanates on glucose isomerization was investigated in terms of the base quantity and strength. The analysis was performed by using an acid–base titration method and FTIR spectroscopy with CHCl <sub>3</sub> as a probe molecule. It is proposed that glucose isomerization on the titanates depends not only on the base amount but also on the base strength. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs"
