Giới thiệu
Neopentyl glycol, often abbreviated as NPG, is an essential raw material in various industrial sectors. Its importance lies in its multifunctional properties, making it an essential component in the synthesis of polymers, resins, coatings, adhesives, etc. The neopentyl glycol raw material has excellent chemical stability, heat resistance and low volatility, ensuring the durability and performance of the final product. Its hydrophobic nature also makes it suitable for applications requiring waterproofing. Essentially, neopentyl glycol is a cornerstone of manufacturing innovation, driving material advancements with its unique properties.
Production of NPG
NPG is produced through the hydrodimerization and hydrogenation of formaldehyde. In this process, formaldehyde molecules dimerize to form hydroxypivaldehyde, which is then hydrogenated to yield NPG. Several catalysts such as nickel or ruthenium can be used to facilitate this reaction. The process takes place between 100-200°C with a pressure of 10-50 bar. Through careful control of temperature, pressure and catalyst selection, high-purity NPG can be obtained from this production method with a yield of over 90%.
