FORMIC PROPIONIC TARTARIC CITRIC ACETIC 23. Although the direct complete oxidation of methanol (or formaldehyde or formic acid, on that matter) to carbon dioxide (COX2) using oxidizing reagents such as KMnOX4 or KX2CrX2OX7 is hard to find in literature, electrochemical oxidation of methanol to COX2 through formaldehyde and formic acid is one of the concepts used in fuel cell research (Ref.1). Sie können Ihre Einstellungen jederzeit ändern. MathJax reference. That's because methanoic acid is also easily oxidised by potassium manganate(VII) solution. Usage of TFA in Pfitzner-Moffat oxidation and Collins vs Jones oxidation. Electrode potentials of these reactions are still debatable, and Koppenol and Rush have collected and calculated some reduction potentials for $\ce{CO2/CO2^{.-}}$ couple and plotted them in a Frost diagram (Ref.2). EC Number 200-579-1. Accordingly, you’d see even under electrochemical conditions, this conversion is not straightforward. Beilstein/REAXYS Number 1209246 . Contains not less than 98.0% of CH 2 O 2. Formic acid contains both an aldehyde as well as an acid group. 3. Formic acid, the simplest of the carboxylic acids, used in processing textiles and leather.

What volume of 0.1500M KMnO4 would be required to react with 1g of formic acid, HC02H, in acid solution? It is sometimes referred to as Baeyer's reagent after the German organic chemist Adolf von Baeyer. With moderate temperatures (< 40 deg C) and a pH of 10 - 11, the H2O2 demand should be about 0.8 parts H2O2 per part HCHO, which translates into an H2O2 cost of about $0.75 USD per lb-HCHO. In fact, it oxidises it all the way to carbon dioxide and water. I wonder if that is the case of methanol. Take 3 drops of both the 'suspects' in 2 different test tubes, add 1 ml of distd water, & 1-2 drops of dilute KMnO4 solution - the formic acid instantly decolorises pink color of KMnO4, while acetic acid will not.
