4,4'-diamino-2-methylazobenzene - Introduction
4,4 '-diamino-2-methylazobenzene is an organic compound whose chemical formula is C8H10N4. The following is a description of the properties, uses, preparation and safety information of the compound:
Nature:
- 4,4 '-diamino-2-methylazobenzene is a pale yellow to orange-yellow crystalline solid.
-At room temperature, it is almost insoluble in water, but soluble in a variety of organic solvents, such as ethanol, dimethyl sulfoxide and chloroform.
-It has a strong ability to absorb ultraviolet light, so it presents a gorgeous color.
-The compound will undergo oxidation in the presence of oxygen.
Use:
- 4,4 '-diamino-2-methylazobenzene is often used as a precursor for dyes and pigments.
-It can be oxidized into compounds of similar structure. These compounds have strong dyeing properties and are widely used in industries such as textiles, inks, plastics and coatings.
-It can also be used as a photosensitive material in the fields of lithography, optical storage and laser printing.
Preparation Method:
- 4,4 '-diamino-2-methylazobenzene can be obtained by reacting aniline with methylacetone. First, aniline and methyl acetone nucleophilic addition reaction, the formation of methylene products. Then, the methylated product connects two azobenzene rings to each other by an azotization reaction to form the target product.
