Ketone formation via decarboxylation reactions of fatty acids using solid hydroxide/oxide catalysts.

Smith, Benjamin and Li, Li and Perera-Solis, Diego and Gildea, Louise and Zholobenko, Vladimir and Dyer, Philip and Greenwell, H. Christopher (2018) 'Ketone formation via decarboxylation reactions of fatty acids using solid hydroxide/oxide catalysts.', Inorganics., 6 (4). p. 121.


A sustainable route to ketones is described where stearone is produced via ketonic decarboxylation of stearic acid mediated by solid base catalysts in yields of up to 97%, at 250 °C. A range of Mg/Al layered double hydroxide (LDH) and mixed metal oxide (MMO) solid base catalysts were prepared with Mg/Al ratios of between 2 and 6 via two synthetic routes, co-precipitation and co-hydration, with each material tested for their catalytic performance. For a given Mg/Al ratio, the LDH and MMO materials showed similar reactivity, with no correlation to the method of preparation. The presence of co-produced oxide phases in the co-hydration catalysts had negligible impact on reactivity.
