One-pot conversion of cellulose to isosorbide using supported metal catalysts and ion-exchange resin

• Cellulose was directly converted into isosorbide in water.
• Supported ruthenium catalyst with ion-exchange resin showed high activity.
• The maximum yield of isosorbide from cellulose was 55.8%.

One-pot conversion of cellulose to isosorbide was investigated by supported metal catalysts and ion-exchange resin in water. The maximum isosorbide yield using supported platinum catalysts and Amberlyst 70 was less than 30%. The isosorbide yield drastically increased with supported ruthenium catalysts instead of supported platinum catalysts and it also increased with the loading of ruthenium on carbon support. One-pot conversion of cellulose to isosorbide by 4 wt.% ruthenium catalyst and Amberlyst 70 proceeded with isosorbide yield of 55.8%.
