Description
Production：
Translucent white orthorhombic crystals or small pieces. The apparent density is 1.80 to 1.85 g/cm3. Soluble in water, slightly soluble in alcohol. It has extremely strong reducibility at high temperature, which can make the dyed color disappear, so it is called the white block. Decomposes in the presence of acid, and decomposes at 120 ° C to produce toxic gases such as formaldehyde and hydrogen sulfide. The water-free hanging white block is very stable, but gradually decomposes in humid air.
