水/二甲基亚砜体系中无机盐高效催化木糖脱水制备糠醛
提出了一种高效的均相催化木糖制备糠醛的方法,探讨了水/二甲基亚砜（DMSO）均相体系中不同类型的无机盐对催化木糖制备糠醛的影响.结果表明,氯盐较硫酸盐和硝酸盐表现出较高的催化活性,其中以SnCl4的催化效果最高.且它与LiCl复配时催化性能更高.当SnCl4的摩尔分数为0.8时,催化效果最好,糠醛收率达56.9%.反应条件优化实验发现,当催化剂与木糖的摩尔比为0.5：1,固液比为1：20,水与DMSO体积比为5：5时,于130 oC下反应6 h,糠醛收率达63%....

| Abstract_FL | An efficient homogeneous catalytic process was developed for the dehydration of xylose to furfural using inorganic salts as catalysts in a water/dimethyl sulfoxide (DMSO) system under mild condi-tion. The effects of the types of inorganic salts were compared. The results showed that chlorides had higher catalytic performance than other salts, and SnCl4 was the most effective chloride. The catalytic activity of paired SnCl4/LiCl catalysts was much higher than that of the single salt, and when the distribution coefficient (χSnCl4) was 0.8, the maximum furfural yield was 56.9%. The effects of the reaction conditions on the furfural yield were also investigated. The highest furfural yield, 63.0%, was achieved at 130 °C for 6 h under the optimized reaction conditions. |
