Me Ph carbonate (MPC) is a versatile carbonate, particularly as an important component in the lithium-ion battery industry. Recently the green synthesis of carbonates from non-toxic feedstocks and efficient catalysts have attracted a considerable amount of interest but the development of a highly active catalyst for this synthesis is a great challenge. Herein, novel Pb-Mg thin nanosheet catalysts with high specific areas and large pore volumes were developed by one-pot hydrothermal approach for the synthesis of MPC without using any solvent. The nanosheets were thoroughly characterized by SEM-EDS, TEM, XPS, NH3-TPD, XRD, BET, and H2-TPR techniques. It is shown that a di-Ph carbonate (DPC) conversion of 56.6% and an MPC selectivity of 98.8% are achieved by a Pb-Mg nanosheet catalyst with 15 wt% Pb. The activity and selectivity values are significantly higher than the previous best value reported by using transition metal-based catalysts. After the reaction, the nanosheets can be separated by simple centrifugation and can be reused many times without a significant loss of catalytic activity, showing excellent stability and recyclability. A possible mechanism was investigated based on these results. This work provides new insight into accomplishing the efficient and green synthesis of MPC and offers a strategy for synthesizing other asym. carbonates. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0COA of Formula: C13H10O3).
Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is 纬-valerolactone.COA of Formula: C13H10O3
