Both aspects of the interest in using ultrasound are illustrated by our results in the field of carbohydrate chemistry. The course of the heterogeneous reaction of glucose with hydrophobic alcohols in acidic medium is directed towards the oligomerisation of glucose because of the wetting of the glucose suspension due to the efficiency of the sonophysical mixing. On the other hand, a sonocatalysis is observed during the course of the oxidation of primary hydroxyl groups in homogeneous aqueous medium by the NaOCl/TEMPO system.
我们在碳水化合物化学领域的研究结果体现了利用超声波的两个方面。在酸性介质中，葡萄糖与疏水醇的多相反应过程朝着葡萄糖的低聚方向进行，这是由于声物理混合的效率导致葡萄糖悬浮液被润湿。另一方面，在均相水介质中，通过NaOCl/TEMPO体系氧化伯羟基的过程中观察到了声催化作用。
