Acetals and hemiacetals; whether or not with other oxygen function, and their halogenated, sulphonated, nitrated or nitrostated derivatives
HS v2022 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, fragrances, and solvents. Acetals and hemiacetals are widely used as intermediates in the production of other chemicals, making them an essential part of the broader chemical industry and global trade.
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 in both batch and continuous processes. Distillation and other separation techniques are commonly used to purify the final products.
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. Specialized equipment, such as reactors, distillation columns, and purification systems, are also necessary for the manufacturing process.
Production outputs
The primary outputs of HS code 2911 are the acetals and hemiacetals themselves, which are then used as intermediates in the production of a wide range of other chemicals. These include 2912 Aldehydes, 2914 Ketones and quinones, and 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).
