This article serves as a guide to this versatile acrylate, detailing its synthesis, properties, applications, and the importance of sourcing it from reputable manufacturers and suppliers.

What is 3,5,5-Trimethylhexyl Acrylate (CAS 45125-03-9)?

3,5,5-Trimethylhexyl Acrylate is an organic compound that belongs to the family of acrylate esters. Its molecular structure features a branched alkyl chain attached to the acrylate group. This specific structure is responsible for many of its desirable properties when incorporated into polymers, including enhanced flexibility, toughness, and modified surface characteristics. It is typically supplied as a liquid with a low viscosity and contains stabilizers like MEHQ to prevent premature polymerization.

Synthesis and Manufacturing Processes

The production of high-purity 3,5,5-Trimethylhexyl Acrylate typically involves direct esterification reactions. The most common industrial routes include:

  • Esterification of Acrylic Acid with 3,5,5-Trimethylhexanol: This is a widely used method where acrylic acid reacts with the corresponding alcohol in the presence of an acid catalyst. Optimization of reaction conditions, including temperature and water removal, is critical for achieving high yields and purity.
  • Alternative Synthesis Routes: Other methods may involve the synthesis of the precursor alcohol (3,5,5-trimethylhexanol) through processes like hydroformylation of diisobutylene, followed by esterification.

Reputable manufacturers employ stringent process controls and purification techniques, such as vacuum distillation, to ensure the final product meets the required purity standards for applications like polymer synthesis and formulation. When you are ready to buy, inquiring about the specific synthesis route and quality assurance processes from your supplier is a wise step.

Key Properties and Applications

The branched nature of the 3,5,5-trimethylhexyl group in CAS 45125-03-9 leads to:

  • Improved Mechanical Properties: Polymers incorporating this monomer exhibit increased flexibility and toughness, making them suitable for durable coatings, adhesives, and impact-resistant materials.
  • Reduced Shrinkage: In UV-curing applications, this monomer contributes to lower shrinkage, which is vital for dimensional accuracy and adhesion.
  • Hydrophobicity: The nonpolar side chain enhances water repellency, beneficial for protective surface treatments.
