Quinoline-3-carboxylic acid ethyl ester is a chemical compound that is used in a variety of applications in the chemical industry.
It is a colorless liquid that is soluble in water and has a strong, unpleasant odor.
The production process for quinoline-3-carboxylic acid ethyl ester involves several steps, including the synthesis of the starting materials, the reaction of the starting materials to form the ester, and the purification of the final product.
The synthesis of the starting materials typically involves the reaction of 3-iodquinoline with sodium hydroxide in the presence of water.
This reaction results in the formation of 3-hydroxyquinoline, which is then treated with ethyl bromide in the presence of a catalyst, such as aluminum chloride, to form quinoline-3-carboxylic acid ethyl ester.
The reaction of the starting materials to form the ester typically occurs in a reaction vessel, which is equipped with a stirring system, a heating system, and a condenser.
The reaction is typically carried out at a temperature of around 100 degrees Celsius and under a pressure of around 5 kilopascals.
The reaction is usually complete within a few hours, and the product is typically allowed to cool to room temperature before it is purified.
The purification of the final product typically involves the use of a variety of techniques, including filtration, distillation, and crystallization.
The product is typically filtered to remove any solids or impurities that may be present, and then distilled to separate the ester from any remaining impurities.
The pure ester is then crystallized from a solvent, such as ethyl acetate, to produce a pure sample of the final product.
In conclusion, the production process for quinoline-3-carboxylic acid ethyl ester involves the synthesis of the starting materials, the reaction of the starting materials to form the ester, and the purification of the final product.
The final product is a colorless liquid that is soluble in water and has a strong, unpleasant odor.
It is used in a variety of applications in the chemical industry, and the production process is relatively straightforward and efficient.
