Paired electrooxidation Part III: Production ofn-butyric acid fromn-butanol

A Novel Synthesis Route of Butyric Acid from Hydrogenation of Maleic Anhydride over Pd/TiO2 Catalysts

“…Esters of the acid are used as the additives for increasing the fruit fragrance and as aromatic compound for the production of perfumes. Butyric acid is currently produced by mainly two processes [10,11]: (i) the oxidation of butanol (ii) the fermentation of starch. Butyric acid can be also prepared by the oxidation of aldehyde, maleic anhydride is considered as a feedstock these days because of its availability and lower price due to the construction of large fluidized-bed plants based on Alusuisse-Lummus Crest and Britist Petroleum Union Chimique Belge technologies.…”

Hidróxido de níquel suportado em carbono: um catalisador de baixo custo para a eletro-oxidação de alcoóis em meio alcalino

“…Um mecanismo geral para a oxidação de alcoóis primários foi proposto por Fleishmann e colaboradores: 35,36 Ni(OH) 2 [37][38][39][40] Com relação ao combustível metanol, o Ni(OH) 2 /C apresentou eletroatividade superior a Pt/C em todos os parâmetros eletroquímicos analisados, confirmando a potencialidade catalítica deste material. A densidade máxima de corrente obtida pelo hidróxido foi de 96 mA mg -1 em relação a 60 mA mg -1 da Pt/C; os resultados estão sumarizados na Tabela 2.…”

NiCo alloy nanoparticles electrodeposited on an electrochemically reduced nitrogen-doped graphene oxide/carbon-ceramic electrode: a low cost electrocatalyst towards methanol and ethanol oxidation

“…As mentioned above, the electrochemically active species in Ni based modied electrodes is NiOOH, so we should expect that the methanol electrooxidation starts with the NiOOH surface formation. [62][63][64][65] The current density of the cathodic peak in reverse scan is considerably less intense because of NiOOH consumption during the methanol oxidation reaction. 66 CVs for the oxidation of ethanol at the CCE (a), ErN-GO/CCE (b), Ni/CCE (c), Ni/ErN-GO/CCE (d), NiCo/CCE (e), NiCo/ErGO/ CCE (f) and NiCo/ErN-GO/CCE (g) in 0.1 M KOH + 0.1 M ethanol at a scan rate of 50 mV s À1 are shown in Fig.…”
