WebThe diols, such as ethane-1,2-diol, which are the products of the reaction with cold dilute potassium manganate(VII), are themselves quite easily oxidised by manganate(VII) ions. That means that the reaction won't stop at this point unless the potassium manganate(VII) solution is very dilute, very cold, and preferably not under acidic conditions. http://chem.ucalgary.ca/courses/351/Carey5th/Ch15/ch15-4-7.html
