Conversion of cellulose to 1-(furan-2-yl)-2-hydroxyethanone has been demonstrated in concentrated zinc chloride solution under microwave irradiation. Compared with the conventional oil-bath heating mode, microwave irradiation significantly reduced the reaction time and increased the yield of 1-(furan-2-yl)-2-hydroxyethanone. A typical degradation reaction with cellulose produced 1-(furan-2-yl)-2-hydroxyethanone in 12.0% molar yield in ZnCl(2) solution (ZnCl(2)-H(2)O ratio=2.25:1, w/w) with microwave irradiation at 600 W for 5 minutes at 135°C.
在微波辐射下，纤维素在浓氯化锌溶液中成功转化为 1-(2-呋喃基)-2-羟基乙酮。与传统油浴加热方式相比，微波辐射显著缩短了反应时间，提高了 1-(2-呋喃基)-2-羟基乙酮的产率。纤维素的典型降解反应在 600 W 微波辐射下，于 135°C 加热 5 分钟，在 ZnCl(2)-H(2)O 质量比为 2.25:1 的 ZnCl(2)溶液中以 12.0%摩尔产率生成 1-(2-呋喃基)-2-羟基乙酮。
