▎ 摘　　要

NOVELTY - A high-efficiency supported silver/graphene oxide catalyst is prepared by adding chloroauric acid in container, adding absolute ethanol to obtain mixed solution, dissolving triphenylphosphine in absolute ethanol, heating to 50-70 degrees C, slowly adding to mixed solution, stirring at room temperature, vacuum filtering, dissolving and diluting filtered solid by dichloromethane, re-crystallizing with petroleum ether to obtain pure solid chloro(triphenylphosphine)gold(I), mixing chloro(triphenylphosphine)gold(I) with silver trifluoromethanesulfonate in dichloromethane, adding benzimidazole ligand at room temperature, filtering reaction liquid by diatomite after 4-5 hours, concentrating filtrate, re-crystallizing by petroleum ether to obtain pyridine imidazole gold complex, dissolving pyridine imidazole gold complex in absolute ethanol, adding into absolute ethanol solution of graphene oxide, refluxing at 80 degrees C for 12-24 hours, centrifuging reaction liquid, washing, and drying. USE - The method is used for preparing high-efficiency supported silver/graphene oxide catalyst in synthesis of bisphenol F and substituted ketone compound (all claimed). ADVANTAGE - The catalyst can be recycled and reused, and has high catalytic efficiency, high product selectivity, high use efficiency, long service life and high catalytic reaction yield. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for application of high-efficiency supported silver/graphene oxide catalyst in synthesis of bisphenol F comprising adding phenol and supported silver/graphene oxide catalyst into reaction container, uniformly stirring at room temperature, adding toluene, slowly adding 37% formaldehyde aqueous solution, heating to 110-120 degrees C, heat preservation reacting for 4-6 hours, layering reaction liquid, taking oil layer as reaction crude product, recycling supported silver/graphene oxide catalyst by filtering reaction liquid, rotary steaming crude product, recycling solvent, vacuum distilling to recover remaining phenol, and re-crystallizing residual product with recycled toluene to obtain 4,4 dihydroxydiphenylmethane.
