建立了以木糖为原料制备糠醛的co2 -水-异丙醇绿色反应体系。首先，研究了简单的co2 -水体系，结果表明木糖对FF的生成有很大的促进作用。co_2在高压下可以提高反应体系的酸度，从而提高FF收率。通过提高反应温度，木糖在co2 -水-异丙醇体系中的转化速度明显加快，转化率为94.41%，FF产率为55.81%。添加适量的NaCl进一步提高了产率至69.20%。其他碳水化合物（阿拉伯糖和木聚糖）也在相同的反应体系中进行了测试，得到了一般的结果。
A novel green reaction system of CO2–water–isopropanol has been developed for the production of furfural (FF) from xylose. Initially, a simple CO2–water system was investigated, and the results showed that the formation of FF from xylose was greatly enhanced. CO2at high pressure could increase the acidity of the reaction system, and thus the FF yield was improved. By raising the reaction temperature, the conversion of xylose was remarkably accelerated in the CO2–water–isopropanol system, leading to an acceptable conversion rate (94.41%) and FF yield (55.81%). Addition of an appropriate amount of NaCl further increased the yield to 69.20%. Other carbohydrates (arabinose and xylan) were also tested in the same reaction system and modest results were obtained.
