Sulfonated nano-sized diamond powder (S-DP) was tested in a typical water-CPME (1:3, v/v) biphasic system and heated in a commercial monowave microwave oven to promote the dehydration of D-xylose into furfural as industrial platform molecule. This new heterogeneous catalyst with a propyl linker between the support and the sulfonyl group expressed remarkable sufficient hydrophilicity, affinity for D-xylose and catalytic activity in presence of NaCl. The solid can act as a strong acidic catalyst without detectable exchange between proton exclusively localized on the surface of the catalyst and sodium ion. It was also stable at 200 °C even after severe recycling treatment. The final optimized condition requires 10 wt% of the catalyst for a maximum furfural yield of 76% when the mixture is heated for 50 min in the current biphasic system.

在典型的水-CPME（1：3，v / v）双相系统中对磺化的纳米级金刚石粉末（S-DP）进行了测试，并在商用单波微波炉中进行了加热，以促进D-木糖脱水成糠醛。平台分子。这种在载体和磺酰基之间具有丙基连接基的新型多相催化剂表现出了显着的足够的亲水性，对D-木糖的亲和力和在NaCl存在下的催化活性。该固体可以充当强酸性催化剂，而在仅位于催化剂表面上的质子与钠离子之间没有可检测的交换。即使经过严格的回收处理，它在200°C的温度下也稳定。当在当前双相系统中将混合物加热50分钟时，最终的最佳条件需要10 wt％的催化剂，最大糠醛收率为76％。
