Dipentaerythritol (CAS 126-58-9)

Product Selling Points

High density cross-linking capability: Featuring six active hydroxyl groups, this specialty polyol allows for the creation of exceptionally durable polymer networks that enhance the hardness and chemical resistance of finished coatings.
Outstanding high temperature performance: The inherent thermal stability of this material makes it a premier component for synthetic esters used in jet engine lubricants and high performance automotive fluids where heat resistance is critical.
Versatile synthetic resin intermediate: This product serves as a fundamental building block for advanced alkyd resins and UV curable monomers, providing manufacturers with the flexibility to engineer high performance industrial finishes.
Reliable industrial quality control: We maintain strict standards for purity and particle size distribution to ensure consistent reaction behavior and final product clarity in every batch delivered to our global partners.

Product Introduction

Dipentaerythritol (Di-PE), identified by CAS 126-58-9, is a high-performance hexa-functional polyol used extensively in the specialty resin and lubricant industries. Appearing as a white, odorless crystalline powder with the chemical formula C10H22O7, Dipentaerythritol is a co-product of pentaerythritol synthesis. It is distinguished by having six primary hydroxyl groups, which provide a higher level of functionality compared to monopentaerythritol. This structural advantage makes Di-PE an essential raw material for the production of dipentaerythritol hexaacrylate (DPHA), high-solids alkyd resins, and complex esters for high-temperature lubrication. Its ability to impart superior durability, heat resistance, and chemical stability makes it a cornerstone of high-end chemical engineering.

Applications

UV-Curable Coatings and Inks

Used as a precursor for hexaacrylate monomers (DPHA) to produce high-gloss, scratch-resistant UV coatings for electronics and flooring.

High-Performance Alkyd Resins

Enables the formulation of high-solids, low-VOC coatings with superior weathering resistance and film hardness for industrial equipment.

Synthetic Lubricants

Reacted with organic acids to produce high-temperature stable polyol esters for use in aviation, automotive, and industrial lubrication systems.

PVC Heat Stabilizers

Acts as a synergistic agent in calcium-zinc (Ca-Zn) stabilizer systems to improve the heat stability and initial coloring of PVC products.

Packaging & Logistics

Standard Packaging: 25 kg multi-layer paper bags with PE inner liner.
Bulk Solutions: 500 kg or 1,000 kg jumbo bags for large-scale production.
FCL Capacity: 18–20 MT (with pallets) per 20'FCL; 22 MT (without pallets).
Storage: Store in a cool, dry, and well-ventilated area. Keep away from moisture and strong oxidizers. Dipentaerythritol is stable under normal storage conditions but is hygroscopic.

Synonyms

Di-PE; Dipentaerythritol; 2,2,2'',2''-Tetrakis(hydroxymethyl)-3,3''-oxydipropan-1-ol; Bis(pentaerythritol).

Matching Materials

Acrylic Acid: Used in the esterification process to produce UV-curable dipentaerythritol hexaacrylate.
Phthalic Anhydride (CAS 85-44-9): A primary co-reactant in the production of high-performance alkyd resins.
Fatty Acids: Used to synthesize high-temperature synthetic lubricant esters.
Calcium/Zinc Stearates: Paired with Di-PE to create high-efficiency heat stabilizers for PVC.

Frequently Asked Questions

What is the main advantage of Di-PE over Mono-pentaerythritol?

Di-PE has six hydroxyl groups compared to four in Mono-pentaerythritol. This leads to a higher cross-linking density, resulting in resins with much better hardness, heat resistance, and chemical durability.

Does it dissolve easily in water?

No, Di-PE has low solubility in cold water. It dissolves much better in hot water or when reacted into resin systems through high-temperature esterification.
