Dipentaerythritol, a polyhydric alcohol, is a solid, white, odorless substance at room temperature. It forms easily through esterification reactions with common organic acids, showcasing low hygroscopicity and air stability. Structurally, it appears as two bonded pentaerythritol molecules and is produced by reacting formaldehyde and acetaldehyde in an alkali presence, typically as a byproduct of pentaerythritol production.
Its applications span across creating alkyd resins for coatings, polyurethane resins for paints and adhesives, rosin esters for adhesives, synthetic lubricants, vinyl chloride plasticizers for soft PVC products, surfactants, cosmetics, cross-linking agents, and explosives. Dipentaerythritol-based products are essential in industries ranging from automotive to textiles and beyond.
Featuring six hydroxy groups, dipentaerythritol is hydrophilic, enabling water solubility despite its considerable molecular weight. It dissolves in water at a few grams per liter at 20°C and has a melting point between 210°C and 220°C.
The molecule consists of two pentaerythritol units linked together, with the chemical formula (HOCH2)3CCH2OCH2C(CH2OH)3. Its six hydroxy groups facilitate a wide range of synthetic reactions, leading to diverse derivative compounds.
As a precursor for multifunctional cross-linkers, dipentaerythritol undergoes esterification with acrylic or methacrylic acid, producing compounds with acryloyl or methacryloyl groups. These cross-linkers enable the polymerization of monomers into highly crosslinked polymer compounds. Examples include dipentaerythritol triacrylate, tetraacrylate, pentaacrylate, and hexaacrylate, showcasing the versatility of dipentaerythritol in advanced material synthesis.
