4,5-Bis(2-methoxyethoxy)-2-nitrobenzonitrile, commonly referred to as Methoxy-Nitro-Benzonitrile (MNB), is a versatile chemical compound that has a wide range of applications in the chemical industry.
It is used as an intermediate in the production of various chemicals, including dyes, pigments, and pharmaceuticals.
Upstream Products
The production of Methoxy-Nitro-Benzonitrile involves several upstream processes, including the synthesis of 2-methoxyethanol and 2-nitrobenzaldehyde.
2-Methoxyethanol is prepared by the reduction of methyl ethanoate using a reducing agent such as lithium aluminum hydride.
The resulting 2-methoxyethanol is then nitrated using nitric acid to produce 2-nitro-1,3-propanedione, which is further hydrolyzed to yield 2-nitrobenzaldehyde.
Downstream Products
Once Methoxy-Nitro-Benzonitrile is synthesized, it can be used as an intermediate in the production of several downstream products.
One of the most common downstream products is 4,5-Diaminopyrimidine (DAP), which is used in the production of dyes and pigments.
The synthesis of DAP from Methoxy-Nitro-Benzonitrile involves several steps, including the oxidation of MNB to 2-nitro-1,4-benzenedicarboxylic acid, the decarboxylation of the acid to 1,4-benzenediacetate, and the condensation of the diacetate with a primary amine, such as ethylamine or aniline, to yield DAP.
Another downstream product of Methoxy-Nitro-Benzonitrile is Tetryloxyphenylmethane (TOPM), which is used as an intermediate in the production of pharmaceuticals.
The synthesis of TOPM from MNB involves several steps, including the oxidation of MNB to 2-nitro-1,4-benzenedicarboxylic acid, the condensation of the acid with formaldehyde to yield 1,4-benzenediacetonitrile, and the coupling of the diacetonitrile with tetrakis(hydroxymethyl)phosphonium chloride to yield TOPM.
Applications
Methoxy-Nitro-Benzonitrile is used as an intermediate in the production of various chemicals, including dyes, pigments, and pharmaceuticals.
It is a versatile chemical that can be used in a wide range of applications, making it an important compound in the chemical industry.
Dyes and Pigments
Dyes and pigments are widely used in various industries, including textiles, plastics, and food packaging.
Methoxy-Nitro-Benzonitrile is used as an intermediate in the production of several dyes and pigments, including 4,5-Diaminopyrimidine (DAP), which is used in the production of reactive dyes for cotton and wool.
Methoxy-Nitro-Benzonitrile is also used in the production of basic dyes, such as acid red 18, and direct dyes, such as methyl orange.
Pharmaceuticals
Methoxy-Nitro-Benzonitrile is used as an intermediate in the production of several pharmaceuticals, including Tetryloxyphenylmethane (TOPM), which is used in the production of several antibiotics, including erythromycin and
