Alcohols; polyhydric, pentaerythritol
HS v2022 Code: 290542
About alcohols; polyhydric, pentaerythritol
HS code 290542 covers the classification of polyhydric alcohols, specifically pentaerythritol. These types of alcohols are essential chemical compounds with a wide range of industrial applications, including the production of alkyd resins, lubricants, and explosives. The global pentaerythritol market is expected to grow steadily in the coming years, driven by increasing demand from various end-use industries, such as paints and coatings, plastics, and personal care products.
Production process
Pentaerythritol is typically produced through the condensation reaction of formaldehyde and acetaldehyde, followed by hydrogenation. The process involves several key steps, including the initial reaction, purification, and final hydrogenation to obtain the desired product. Advanced manufacturing techniques, such as continuous processing and optimization of reaction conditions, have helped improve the efficiency and yield of pentaerythritol production.
Production inputs
The main inputs required for the production of pentaerythritol include formaldehyde, acetaldehyde, and hydrogen. Additionally, the process may require various catalysts, solvents, and other auxiliary chemicals. Specialized equipment, such as reactors, distillation columns, and hydrogenation units, are also essential for the manufacturing of this polyhydric alcohol.
Production outputs
The primary output of HS code 290542 is pentaerythritol, which is then used as a feedstock for the production of a wide range of downstream products. Some of the key industries that consume pentaerythritol include 320910 Paints and varnishes, 340211 Organic surface-active agents, and 360200 Explosives. Pentaerythritol is also used in the manufacture of 290920 Epoxide resins and 290560 Alcohols, other polyhydric, further expanding its applications within the broader chemical industry.
