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

HS code 290911 covers the classification of diethyl ether, a versatile organic compound with a wide range of industrial applications. As an acyclic ether, diethyl ether is an important solvent and chemical intermediate, finding use in the production of various pharmaceuticals, plastics, and other essential materials. This code sits within the broader category of organic chemicals, a crucial sector that underpins the global economy through the supply of raw materials and specialty chemicals.

Production process

Diethyl ether is typically produced through the catalytic reaction of ethanol with sulfuric acid. This process, known as the Fischer-Speier ether synthesis, involves the dehydration of ethanol to form the ether compound. The reaction is carried out under controlled temperature and pressure conditions, with the resulting diethyl ether then purified through distillation to meet the required purity standards.

Production inputs

The main inputs for the production of diethyl ether under HS code 290911 include ethanol as the primary raw material, as well as sulfuric acid as the catalyst. Additionally, the process requires access to specialized equipment such as reaction vessels, distillation columns, and other process control infrastructure. Energy sources, such as steam or electricity, are also necessary to power the production facilities.

Production outputs

The primary output of HS code 290911 is diethyl ether, which is then consumed by a variety of downstream industries. These include the pharmaceutical sector, which uses diethyl ether as a solvent and in the synthesis of various drug compounds 300000 Pharmaceutical products. The chemical industry also utilizes diethyl ether in the production of plastics, resins, and other polymeric materials 390000 Plastics and articles thereof. Additionally, diethyl ether finds application in the fuel and lubricant industries, as well as in the manufacture of certain household and personal care products.
