The Production Process of 2-CHLORO-3-CYANOQUINOLINE

The production process of 2-chloro-3-cyanopyridine, commonly referred to as CCP, is an important process in the chemical industry.
CCP is used as a building block for the synthesis of various pharmaceuticals, agrochemicals, and other chemicals.
The production process of CCP involves several steps, which are outlined below.

1. Manufacture of Chlorine: The first step in the production of CCP is the manufacture of chlorine.
   Chlorine is manufactured by the electrolysis of brine, which involves the electrolysis of sodium chloride in water to produce chlorine gas and hydrogen gas.
   
2. Production of Hydrogen Chloride: The chlorine gas produced in the previous step is then converted into hydrogen chloride by passing it through a bed of activated carbon.
   This process removes any impurities present in the chlorine gas and results in the production of pure hydrogen chloride.
   
3. Manufacture of Cyanogen Chloride: The next step in the production of CCP is the manufacture of cyanogen chloride.
   Cyanogen chloride is produced by passing hydrogen chloride gas over a mixture of sodium hydroxide and hydrogen cyanide.
   This process results in the formation of a solution of cyanogen chloride in water.
   
4. Hydrolysis of Cyanogen Chloride: The next step in the production of CCP is the hydrolysis of cyanogen chloride.
   Hydrolysis is the process of breaking down a compound using water.
   In this case, the cyanogen chloride is hydrolyzed using water to produce hydrogen cyanide and sodium hydroxide.
   
5. Nitration of Hydrogen Cyanide: The next step in the production of CCP is the nitration of hydrogen cyanide.
   Hydrogen cyanide is nitrated using nitric acid to produce 2-chloro-3-cyanopyridine.
   
6. Purification of 2-Chloro-3-Cyanopyridine: The final step in the production of CCP is the purification of the 2-chloro-3-cyanopyridine.
   This is done by crystallization, which involves cooling the solution of 2-chloro-3-cyanopyridine and allowing it to crystallize.
   The crystals are then separated from the solution and dried to produce pure CCP.
   

In conclusion, the production process of 2-chloro-3-cyanopyridine involves several steps, which are all carefully designed to ensure that the final product is pure and of high quality.
The process involves the manufacture of chlorine, the production of hydrogen chloride, the manufacture of cyanogen chloride, the hydrolysis of cyanogen chloride, the nitration of hydrogen cyanide, and the purification of 2-chloro-3-cyanopyridine.
The production process of CCP is a complex and multistep process that requires careful attention to detail and the use of specialized equipment and chemicals.
