Acetals and hemiacetals; whether or not with other oxygen function, and their halogenated, sulphonated, nitrated or nitrostated derivatives

HS v2017 Code: 2911

About acetals and hemiacetals; whether or not with other oxygen function, and their halogenated, sulphonated, nitrated or nitrostated derivatives

HS code 2911 covers a group of organic compounds known as acetals and hemiacetals. These compounds play a crucial role in various industries, including pharmaceuticals, flavors, and fragrances. They are valued for their unique chemical properties and versatility, making them an essential part of the global chemical supply chain.

Production process

The production of acetals and hemiacetals typically involves the reaction of alcohols with aldehydes or ketones. This process is often catalyzed by acids or bases, and can be carried out using a variety of techniques, such as distillation, extraction, and crystallization. Manufacturers may also employ specialized methods, such as the use of membrane reactors or continuous flow processes, to optimize efficiency and product quality.

Production inputs

The main inputs required for the production of acetals and hemiacetals include alcohols, aldehydes, and ketones, as well as various catalysts and solvents. Manufacturers may also require specialized equipment, such as reactors, distillation columns, and drying systems. Additionally, the industry relies on a range of supporting industries, such as 2901 Acyclic hydrocarbons, 2902 Cyclic hydrocarbons, and 2905 Acyclic alcohols and their halogenated, sulphonated, nitrated or nitrosated derivatives.

Production outputs

The primary outputs of the acetals and hemiacetals industry are the various compounds classified under HS code 2911. These products are widely used in the production of pharmaceuticals, flavors, fragrances, and other specialty chemicals. The outputs of this industry may be consumed by manufacturers in 2909 (Ethers, ether-alcohols, ether-phenols, ether-alcohol-phenols, alcohol peroxides, ether peroxides, ketone peroxides (whether or not chemically defined), and their halogenated, sulphonated, nitrated or nitrosated derivatives), 2914 Ketones and quinones, whether or not with other oxygen function, and their halogenated, sulphonated, nitrated or nitrosated derivatives, and 2918 Carboxylic acids with additional oxygen function and their anhydrides, halides, peroxides and peroxyacids; their halogenated, sulphonated, nitrated or nitrosated derivatives.
