- Abstract:
- Ethyl levulinate was prepared by USY as solid aeid eatalyst from eellulose in ethanol. The effeets oldifferent parameters such as liquid -solid ratio, reaetion temperalure, eatalyst dosage, reaetion time and waterdosage on ethyl levulinate yield and mass of diethy ether and solid residue were also studied. And the influ.enee of eatalyst reuse eyele on elhyl levulinate yield was further investigated. Experimental results showed thatthe highest yield of ethyl levulinate was 14.95 mol96 under the following conditions: liquid-solid ratio 15, re.aetion temperature 220 ℃ , eatalyst dosage 2. 596 , reaction time 2 h and water dosage 0. lt was found that thereeovered eatalyst still remained high catalytie aetivity afer being reused for five times.
