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

neopentyl glycol raw material

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%.

Các ứng dụng của NPG

As a diol with four carbon atoms, NPG possesses desirable properties that make it suitable for a wide range of applications. Let’s take a closer look at some of its key uses:

  • Nhựa polyester: NPG is widely used in the production of alkyd and polyester resins that find applications in paints, coatings and adhesives. It improves the flexibility and weatherability of these resins.
  • Polyurethane: Around 60% of global NPG production goes into manufacturing polyurethane products like elastomers, foams, and coatings. NPG enhances the physical properties of polyurethanes.
  • Plasticizers: NPG and its derivatives function as internal plasticizers for PVC and other plastics. It enhances flexibility, transparency and low-temperature performance of plastics.
  • Lube Oil Additives: Esters of NPG are used as pour point depressants and anti-wear additives in automotive and industrial lubricating oils.
