About ethers; acyclic, and their halogenated, sulphonated, nitrated or nitrosated derivatives, diethyl ether

HS code 290911 covers the classification of diethyl ether, a widely used organic compound with diverse industrial applications. As an acyclic ether, diethyl ether is an important solvent, anesthetic, and chemical intermediate, playing a crucial role in various manufacturing processes and industries. Its versatility and global demand make it a significant component of the broader chemical and petrochemical sectors, which are vital to the global economy.

Production process

Diethyl ether is primarily produced through the catalytic dehydration of ethanol. This process involves the reaction of ethanol over an acidic catalyst, such as sulfuric acid or a solid acid catalyst, to form the ether compound. The reaction is carried out at elevated temperatures, typically between 100-150°C, to drive the equilibrium towards the formation of diethyl ether. Distillation is then used to purify the final product.

Production inputs

The main inputs required for the production of diethyl ether include ethanol as the primary raw material, as well as catalysts such as sulfuric acid or solid acid catalysts. Additionally, the process requires energy in the form of heat to facilitate the dehydration reaction. Specialized equipment, such as reactors, distillation columns, and storage tanks, are also necessary for the efficient production and handling of diethyl ether.

Production outputs

Diethyl ether, classified under HS code 290911, is a versatile chemical with a wide range of applications. It is commonly used as a solvent in various industries, including the production of pharmaceuticals, paints, and adhesives. Diethyl ether is also employed as an anesthetic agent in the medical field. Additionally, it serves as a chemical intermediate in the synthesis of other organic compounds, such as those classified under 290919 Ethers; acyclic, and their halogenated, sulphonated, nitrated or nitrosated derivatives, other and 290920 Ethers; cyclic, and their halogenated, sulphonated, nitrated or nitrosated derivatives.
