The catalytic and radical mechanism for ethanol oxidation to acetic acid

Liquid-phase ethanol oxidation to acetic acid proceeds in two steps: catalytic ethanol oxidation and non-catalytic acetaldehyde autoxidation. The balance between the two-steps coincides in the acetic acid formation and provides information for designing selective catalysts.

Competitive C–C and C–H bond scission in the ethanol oxidation reaction on Cu(100) and the effect of an alkaline environment

C–C bond scission in EOR on Cu(100) will occur in CH2CO but acetic acid formation will preside under alkaline conditions.

Selective Pyrolysis Behaviors of Willow Catalyzed via Phosphoric Acid

Willow is an abundant plant in many countries all over the world. It has an extremely rapid growing rate, and it can be considered as a sustainable raw material wood resource. In this study, H3PO4of catalyzed willow pyrolysis was investigated by means of CP-GC-MS. Moreover pyrolysis products such as furfural, levoglucosenone,levoglucosan and phenolic compounds was ananlyzed. The results indicate that H3PO4shows increased selectivity towards sugar and furan compounds at the expense of acetic acid and phenolic compounds. The biomass treatment with H3PO4enhances dehydration and decarbonylation of levoglucosan resulting in more furfural and levoglucosenone, promoting the lignin to form carbon rather than phenolic compounds. and inhibit acetic acid formation.. The content of the major sugar compounds reached 50% in the prensence of catalyst. The content of the major furan compounds enhanced, mainly furfural.
