chromate(1-), bis[3-[4,5-dihydro-4-[(2-hydroxy-5-methyl-3-nitrophenyl)azo]-3-me - Introduction
sodium bis[3-[4,5-dihydro-4-[(azo) azo]-] benzene-1-sulphonamidato(2-)]chromate(1-), also known as sodium chromate, is a chemical compound having the following properties, uses, methods of manufacture and safety information:
Nature:
-Appearance: Sodium chromate is a dark red crystalline solid.
-Solubility: Soluble in water and acidic solutions.
-Stability: relatively stable in a humid environment, but easy to decompose in a dry environment.
Use:
-Sodium chromate is an important chromium complex, commonly used in catalysts, dye synthesis and organic synthesis.
-it is often used in organic synthesis oxidation reaction, the synthesis of aromatic sulfonic acid and aromatic ketone reduction reaction.
Preparation Method:
-Sodium chromate is usually prepared by the method of synthesizing chromium complexes. In the synthesis process, 4,5-dihydro -4-[(2-hydroxy-5-methyl-3-nitrobenzene) azo-3-methyl-5-oxo-1h-1-pyrazolyl]] benzenesulfonamide is reacted with chromic acid, followed by addition of the sodium salt to form sodium chromate.
Safety Information:
-Sodium chromate is generally non-toxic to humans. However, as a chemical, it should still be treated with caution.
-Avoid skin contact and ingestion. If contact occurs, rinse immediately with plenty of water.
-Wear appropriate personal protective equipment such as gloves, safety glasses and protective clothing during use.
-It should be stored in a dry, ventilated place, separated from combustibles, oxidants and acids.
