摘要：

The synthesis of propylene glycol (PG) and dipropylene glycol (DPG) was carried out by the hydrolysis of propylene oxide over solid base catalysts. Among them, sol-gel derived Na2O-ZrO2 showed the excellent performance. It was found that Na2O-ZrO2 had a mesoporous framework in which Na2O nanoparticles were homogeneously dispersed. Such a structure led to the strong basicity and then the excellent performance in the hydrolysis of propylene oxide. As a result, one-pot synthesis of propylene glycol (PG) and dipropylene glycol (DPG) could take place at a low H2O/PO ratio of 3 without any condensation reactions.
