1. Stage 1: Anthranilic acid nitrate

Anthranilic acid nitrate is the first intermediate product in the production of quinolone.
To prepare anthranilic acid nitrate, anthranilic acid and sodium nitrate are Reacted in the presence of a solvent such as water or acetone.
The reaction produces anthranilic acid nitrate, which is then purified by recrystallization to obtain a pure sample.

1. Stage 2: N-Formylated Anthranilic Acid

N-Formylated anthranilic acid is produced by the reaction of anthranilic acid nitrate with formaldehyde in the presence of an acid catalyst such as sulfuric acid.
The reaction occurs in several stages, and the product is purified by precipitation and filtration.

1. Stage 3: Nitro Anthranilic Acid

Nitro anthranilic acid is the next intermediate product in the production of quinolone.
To prepare nitro anthranilic acid, N-formylated anthranilic acid is treated with nitric acid in the presence of a solvent such as water or acetone.
The product is then purified by recrystallization.

1. Stage 4: Quinolone

Quinolone is produced by treating nitro anthranilic acid with sodium hydroxide in the presence of water.
The product is then purified by recrystallization and dried to obtain a pure sample.

1. Purification of the Product

The purification process of quinolone is critical to ensure the quality of the final product.
The purification process involves several steps, including recrystallization, filtration, and drying.
The purified product is then packaged and stored under appropriate conditions until it is used in subsequent processes.

In conclusion, the production process of 5,6,7,8-TETRAHYDROQUINOLINONE-5 involves several stages, starting from the preparation of raw materials to the purification of the final product.
Each stage requires careful monitoring and control to ensure the quality of the final product.
The production process of quinolone is complex and requires skilled operators, advanced equipment, and a controlled environment to ensure maximum efficiency and productquality.
