A series of metal manganese-cerium silicon composite aerogel supported Pd catalysts were prepared by the in-situ method, the precipitation method and the impregnation method. The catalysts were applied to synthesize di-Ph carbonate (DPC) by oxidative carbonylation. The effects of different preparation methods and composite metal oxide contents on catalytic activities were studied. The prepared catalysts were characterized by XRD, FTIR, BET, TEM, H2-TPR and XPS. The results showed that the metal composite method had a great influence on the catalyst particle size and sp. surface area; the low temperature oxidation performance and surface oxygen species content of the catalysts prepared by different methods were different. The catalyst prepared by the impregnation method has a large sp. surface area and particle size, good low-temperature oxidation performance and more surface adsorption oxygen, which helps to improve the multi-step electron transfer efficiency, to promote the regeneration of the active component Pd2+ and to increase catalytic activity. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Application In Synthesis of Diphenyl carbonate).
Diphenyl carbonate (cas: 102-09-0) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Application In Synthesis of Diphenyl carbonate
