Integration of anodic and cathodic processes for the synergistic electrochemical production of peracetic acid

Efficient in-situ production of peracetic acid is an unreached milestone of electrochemical engineering. Previous attempts in the production of peracetic acid were focused either on the cathodic production of hydrogen peroxide and its further addition to acetic acid solutions or on the oxidation of...

Los intentos anteriores en la producción de ácido peracético se centraron en la producción catódica de peróxido de hidrógeno y su posterior adición a soluciones de ácido acético o en la oxidación de una materia prima adecuada (vg ácido acético, acetaldehído , etanol). En el presente trabajo, la oxidación de ácido acético por un ánodo de diamante dopado con boro (BDD) se integró con la producción catódica de peróxido de hidrógeno usando un electrodo de difusión de gas de fieltro de carbono . Se observa un marcado efecto sinérgico (coeficiente de sinergia de 192,0 13,1%) cuando la oxidación del ácido acético por hidroxiloLos radicales se realizan junto con la producción catódica de peróxido de hidrógeno. Se obtuvo una eficiencia máxima de producción de PAA del 19,87%, valor muy superior a trabajos anteriores basados ​​en la oxidación del ácido acético por ánodos BDD y aproximadamente el doble del valor óptimo reportado en estudios basados ​​en la producción de peróxido de hidrógeno.Elsevier202120212016info:eu-repo/semantics/articleapplication/pdfapplication/pdfhttp://hdl.handle.net/10578/29166reponame:RUIdeRA.
