DIPENTAERYTHRITOL
Dipentaerythritol is a white, crystalline, odorless solid with the chemical formula C10H22O7. It is a polyhydric alcohol containing
five hydroxyl groups, making it highly hydrophilic and enabling it to form numerous hydrogen bonds. This characteristic contributes
to its excellent solubility in water and polar organic solvents. It has a high melting point of approximately 220-225°C and is stable
under normal conditions. Dipentaerythritol is non-volatile and exhibits low toxicity, which makes it safe for various industrial
applications. It is primarily used in the manufacture of alkyd resins, synthetic lubricants, and plasticizers due to its ability to
enhance thermal stability, durability, and resistance to oxidation. Additionally, its multi-functional nature allows it to serve as a
building block in the synthesis of various polymers and chemicals. The compound's structural complexity also enables it to
improve the performance characteristics of coatings, adhesives, and sealants.
