4-氨基间二甲苯 - Uses and synthesis methods
chemical properties
Colorless oily liquid. The color becomes darker in light and air. Slightly soluble in water, soluble in ethanol, ether, benzene and acid solutions.
Use
2, 4-dimethylaniline is an intermediate for the synthesis of insecticidal and acaricide monoformamidine and amitraz, and can also be used to make azo dyes.
An important intermediate of azo dyes, it can be used to prepare latex colorants, and can also be used in organic synthesis and drug manufacturing.
Production method
2, 4-dimethylaniline is from m-xylene through nitration to obtain 2, 4-dimethylnitrobenzene and 2, 6-dimethylnitrobenzene. After rectification, 2, 4-dimethylnitrobenzene undergoes catalytic hydrogenation and reduction to obtain products.
