The production process of 4,5-Bis(2-methoxyethoxy)-2-nitrobenzonitrile involves several steps, including the synthesis of its constituent chemicals and their subsequent reaction to form the final compound.
Here is a brief overview of the production process of 4,5-Bis(2-methoxyethoxy)-2-nitrobenzonitrile:

1. Synthesis of methyl nitrate: The synthesis of methyl nitrate is the first step in the production of BMEMN.
   Methyl nitrate is prepared by the reaction of methanol with nitric acid, followed by hydrolysis of the resulting nitrate ester with sodium hydroxide.
   The resulting methyl nitrate is then used as the starting material for the next step.
   
2. Synthesis of 2-methoxyethanol: The next step in the production of BMEMN is the synthesis of 2-methoxyethanol, which is the precursor for the synthesis of the nitrobenzene ring.
   2-Methoxyethanol is prepared by the reaction of ethylene oxide with sodium methoxide in the presence of dimethyl sulfate.
   
3. Synthesis of nitrobenzene: The synthesis of nitrobenzene is the next step in the production of BMEMN.
   Nitrobenzene is prepared by the nitration of benzene with nitric acid and sulfuric acid.
   
4. Synthesis of 4,5-dihydroxy-2-nitrobenzene: The synthesis of 4,5-dihydroxy-2-nitrobenzene is the next step in the production of BMEMN.
   4,5-Dihydroxy-2-nitrobenzene is prepared by the reaction of nitrobenzene with a mixture of sodium hydroxide and hydrogen peroxide.
   
5. Synthesis of 4,5-dihydroxy-2-nitrobenzaldehyde: The next step in the production of BMEMN is the synthesis of 4,5-dihydroxy-2-nitrobenzaldehyde, which is the aldehyde form of the nitrobenzene ring.
   4,5-Dihydroxy-2-nitrobenzaldehyde is prepared by the catalytic reduction of 4,5-dihydroxy-2-nitrobenzene with hydrogen in the presence of a catalyst such as palladium on barium sulfate.
   
6. Synthesis of 4,5-Bis(2-methoxyethoxy)-2-nitrobenzonitrile: The final step in the production of BMEMN is the reaction of 4,5-dihydroxy-2-nitrobenzaldehyde with methyl nitrate in the presence of an acid catalyst, such as sulfuric acid.
   The reaction results in the formation of 4,5-Bis(2-methoxyethoxy)-2-nitrobenzonitrile.
   

Overall, the production process of 4,5-Bis(2-methoxyethoxy)-2-nitrobenzonitrile involves several steps, including the synthesis of the constituent chemicals and their subsequent reaction to form the final compound.
