Wen, Zhe published the artcileCatalytic ethanolysis of microcrystalline cellulose over a sulfonated hydrothermal carbon catalyst, Category: esters-buliding-blocks, the main research area is catalytic ethanolysis microcrystalline cellulose sulfonated hydrothermal carbon catalyst.
The catalytic ethanolysis of microcrystalline cellulose in supercritical ethanol is examined over a sulfonated hydrothermal carbon catalyst (SHTC). SHTC is amorphous carbon containing -OH, -COOH and -SO3H groups with total acidity of 7.15 mmol/g and -SO3H acidity of 1.72 mmol/g. SHTC shows high catalytic activity towards the ethanolysis of cellulose in supercritical ethanol. Complete conversion of microcrystalline cellulose with high yields of Et levulinate and Et glucoside is obtained. The reaction temperature, time and catalyst amount have significant effects on the catalytic performances of SHTC. Appropriate reaction time and less catalyst amount are favorable for the production of Et glucoside, while prolonged reaction time and appropriate catalyst amount favor the production of Et levulinate. The highest yield of Et glucoside as 420.9 mg/g cellulose is obtained over 0.1 g SHTC at 245°C for 1 h. The highest yield of Et levulinate as 817.6 mg/g cellulose is achieved over 0.3 g SHTC at 245°C for 1 h. SHTC shows good stability in the recycle experiments with slight loss of catalytic activity.
