Researchers at Dalian Institute of Chemical Physics Release New Data on Ketones

June 24, 2014



By a News Reporter-Staff News Editor at Life Science Weekly -- Fresh data on Ketones are presented in a new report. According to news originating from Dalian, People's Republic of China, by NewsRx correspondents, research stated, "The polymer-inorganic hybrid core-shell nanospheres with N-(para-toluenesulfonyl)-1,2-diphenylethylenediamine in the core and the poly(methyl acrylate) (PMA) polymer in the shell were prepared by using a sol-gel process. The surface properties of solid catalysts were modified by controlling PMA and the cetyltrimethylammonium bromide surfactant in the shell."

Our news journalists obtained a quote from the research from the Dalian Institute of Chemical Physics, "The water contact angle results suggest that the presence of PMA and cetyltrimethylammonium bromide in the shell increases the surface hydrophobicity. In the Rh-catalyzed transfer hydrogenation of aromatic ketones in aqueous HCOONa, the solid catalyst with higher surface hydrophobicity demonstrates higher activity, which suggests that suitable surface properties increase the reaction rate by increasing the diffusion rates of hydrophobic substrates."

According to the news editors, the research concluded: "Furthermore, this heterogeneous catalyst can be reused conveniently without loss of ee values."
