The Synthetic Routes of 1,2-Benzenediacetic acid

1,2-Benzenediacetic acid, also known as benzene diacetic acid, is a versatile organic compound that is commonly used in the chemical industry.
It is a white or slightly yellowish solid that is soluble in water and has a characteristic odor.
Benzene diacetic acid is used in a variety of applications, including the production of dyes, pharmaceuticals, and other chemical products.
In this article, we will explore the synthetic routes for producing benzene diacetic acid and the various applications of this versatile compound.

One of the most common methods for producing benzene diacetic acid is through the reaction of benzene with acetic anhydride in the presence of an acid catalyst.
This reaction is known as the Bouveault-Blanc-Krebs (BBK) reaction, and it involves the following steps:

1. Benzene is treated with acetic anhydride and an acid catalyst, such as sulfuric acid, to form benzene diacetic acid.
   
2. The resulting product is then hydrolyzed, which involves the addition of water to the reaction mixture.
   This step converts the benzene diacetic acid into its diacid form, which is then further processed to produce the final product.
   

Another method for producing benzene diacetic acid involves the oxidation of benzene using a combination of nitric acid and sulfuric acid.
This reaction is known as the Phillips reaction, and it involves the following steps:

1. Benzene is treated with nitric acid and sulfuric acid to form an intermediate compound.
   
2. The intermediate compound is then hydrolyzed, which involves the addition of water to the reaction mixture.
   This step converts the compound into its diacid form, which is then further processed to produce the final product.
   

Both of these synthetic routes involve the use of strong acids and can be hazardous if proper safety precautions are not taken.
In addition, these methods can be expensive and may produce impurities that need to be removed through additional processing steps.

One alternative method for producing benzene diacetic acid involves the use of a biotechnological process.
This process involves the use of bacteria that are capable of converting benzene
