1、 Overview

Commonly known as manganous oxide. Molecular formula: KMnO4 molecular weight: 158.04

Property: dark purple, metallic luster crystal, belonging to orthorhombic system., When heated to 240 ℃, it decomposes and releases oxygen. It is a strong oxidant; It is a deep purplish red solution dissolved in water, soluble in acetone and methanol, and decomposed in case of ethanol and hydrogen peroxide.

2、 Use

It is used as bleaching agent for special fabrics, oils, waxes and resins, oxidant for the purification of inorganic salt products, water treatment, sewage purification and bactericide in agriculture. In the circuit board process, it is mainly used for drilling dirt in the hole after drilling.

3、 Product quality（GB1608-2008）

Appearance: dark purple crystal

Content (KMnO4)% ≥ 99.1

Chloride (CL)% ≤ 0.02

Sulfate (calculated as SO42 -)% ≤ 0.10

Water insoluble matter% ≤ 0.20

4、 Packaging and storage

50kg per barrel. It should be sealed and stored in a cool, dry and ventilated place. Do not be heated during transportation and storage, let alone exposed to fire. Contact with organic matter will cause combustion and even explosion.

5、 Safety measures

When the skin is splashed with potassium permanganate solution, the black spots caused by reduction are attached to the skin, which can be removed by washing with water and then smearing with dilute sodium bisulfite solution. If it is accidentally splashed into your eyes, you will feel burning. You should immediately wash it again with a large amount of distilled water, and then wash it with ascorbic acid solution once or twice, and then ask a doctor for treatment.

6、 Others

The purchase of potassium permanganate and potassium permanganate chemicals shall be filed with the public security department.
