Effect of Reaction Parameters on the Production of Ethyl Levulinate from Glucose in Ethanol

Abstract:

In order to explore the forming rules of ethyl levulinate from glucose in ethanol, several reaction parameters including the initial glucose concentration (10~30 g/L), sulfuric acid concentration (0.1~2 wt%), temperature (170~200 °C) and water addition were investigate, respectively. In addition, effect of the acid concentration on ethanol conversion was also studied. The results show that lower initial glucose concentration is helpful to improve the ethyl levulinate yield, and higher acid concentration can improve the conversion of glucose to ethyl levulinate, which also can improve the condensation of the ethanol. However, higher temperature is unfavorable for the increase of ethyl levulinate yield, and the ethyl levulinate decreased significantly with the increase of water addition.
