Classification Code of Manganese dioxide (CAS NO.1313-13-9): Reproductive Effect

Manganese dioxide History

The chemical properties of Manganese dioxide have been well examined since relatively pure materials have long been readily found or prepared. The manganese dioxide was subsequently recovered by the Weldon process.In molten KOH in the presence of oxygen, MnO2 reacts to give the manganate anion, as discussed below under Applications.

Manganese dioxide Uses

One of Manganese dioxide (CAS NO.1313-13-9) first uses was in glass making. In modern times, the predominant application of Manganese dioxide is as a component of dry cell batteries. A specialized use of manganese dioxide is as an oxidant in organic synthesis. The principal use for MnO2 is for dry-cell batteries, such as the alkaline battery and the zinc-carbon battery. MnO2 is also used for production of MnO4–. It is used extensively as an oxidizing agent in organic synthesis, for example, for the oxidation of allylic alcohols.

Manganese dioxide Production

The natural occuring Manganese dioxide contains impurities and a considerable amount of manganese(III) ions. The production of synthetic manganese dioxide is important. Two groups of methods are used, yielding chemical manganese dioxide (CMD) and electrolytical manganese dioxide (EMD). The CMD is mostly used for the production of ferrites, while the EMD is used for the production of batteries.
