Corresponding authors, a with the reproduced material. 1-Propanol is manufactured by catalytic hydrogenation of propionaldehyde. Propanal can be converted into propanoic acid by oxidation of propanal in the presence of strong oxidising agent such as KMno4. Preparation. Propanol reacts with strong oxidizing agents such as H + / KMnO 4 or H + / K 2 CrO 4 or H + / K 2 Cr 2 O 7 to give propanoic acid. Propanoic acid and various direct sodium or calcium salt formulations of the acid are currently most commonly approved and indicated by organizations like the FDA and EMA for use as an antibacterial food additive preservative in animal feed and food for human consumption [L2715, L2716]. • to reproduce figures, diagrams etc. The chemical equation to convert propanol to propanoic acid is H+/KMnO4 the whole article in a third party publication with the exception of reproduction Polypropylene was synthesized via two steps.
