  磺化氧化石墨烯作为一种高效的固体酸碳催化剂，用于多元醇酯化脂肪酸

  摘要：

  背景：脂肪酸与醇，尤其是多元醇（聚羟基醇）的酯已在合成油脂，合成润滑剂，化妆品，食品和油漆行业中得到了广泛应用。工业上或常规的酯化反应是通过在均相性质的酸催化剂存在下使羧酸与醇缩合来进行的。由于其安全的操作性，稳定性，容易的回收和用于酯化反应的再循环能力，非均相/固体酸催化剂的开发已经引起了极大的科学兴趣。但是，已报道的方法已用于酸与一元醇的酯化反应。据我们所知，尚无关于使用石墨烯基碳催化剂将脂肪酸与多羟基醇酯化的报道。 方法：采用两步法合成所需的磺化氧化石墨烯（SGO），第一步包括将石墨氧化，然后在重氮化条件下用磺胺酸磺化以合成SGO，从而合成氧化石墨烯（GO）。使用5 wt％的SGO作为催化剂在甲苯中于110°C进行脂肪酸与多羟基醇的酯化反应6小时。 结果：作为模型实例，进行了大量实验以优化2，2-二甲基-1，3-丙二醇（DMPD）与己酸（C6酸）酯化的反应参数。发现酯化的最佳条件是5
