Diol with mno2

  • El producto recibe el nombre de glicol (o diol, di-alcohol) y la reacción a menudo se conoce como oxhidrilación debido a que se adicionan grupos oxhidrilo al alqueno. Dos reactivos comunes, que logran esta transformación, son (1) el permanganato de potasio acuoso, con frecuencia en solución alcalina diluida y (2) tetróxido de osmio, OsO4 ...

    Mar 15, 2008 · Then 5 ml of Na2CO3 was added.After added Na2CO3 the purple colour of KMnO4 turned into brown colour.Then this mixure was boiled.We had to cheack the odor of the product. I think It should be the odor of cinnamon. But I failed to get that odor.Did KMnO4 turn in to MnO2? Then Can MnO2 reduce the cinnamic acid into cinnamaldehyde ?

    If MnO2 were able to react and not just catalyze, the titration would not work, and since I've done the titration, I had to look up the possible conflict. Turns out, the titration works because it's done in acidic conditions, and MnO2 is not much of a catalyst in acid.

Manganese oxide is the inorganic compound with the formula MnO 2. This blackish or brown solid occurs naturally as the mineral pyrolusite, which is the main ore of manganese and a component of manganese nodules. The principal use for MnO 2 is for dry-cell batteries, such as the alkaline battery and the zinc-carbon battery. MnO 2 is also used as a pigment and as a precursor to other manganese compounds, such as KMnO 4. It is used as a reagent in organic synthesis, for example, for the oxidation o
