Cyclohexyl Acrylate, identified by its CAS number 3066-71-5, is a versatile acrylic ester that serves as a fundamental building block in various chemical industries. Its unique structure, combining an acrylate functional group with a cyclohexyl ring, imparts specific physical and chemical properties that make it highly sought after for applications ranging from advanced polymers to specialized coatings. For researchers, formulators, and procurement specialists, a thorough understanding of this compound is key to leveraging its full potential. This article provides an overview of Cyclohexyl Acrylate’s properties, synthesis, and its diverse applications, emphasizing the importance of sourcing from reliable manufacturers.

Key Physical and Chemical Properties

Cyclohexyl Acrylate is typically presented as a colorless liquid with a characteristic ester odor. Its molecular formula is C9H14O2, and it has a molecular weight of approximately 154.21 g/mol. Key physical properties include a boiling point around 182-184°C and a density close to 0.975 g/cm³. The refractive index is approximately 1.4600. As an acrylate ester, it possesses a reactive vinyl group that readily participates in free-radical polymerization and copolymerization reactions. This reactivity is central to its use in creating polymers with tailored properties. The presence of the cyclohexyl group influences the polymer's glass transition temperature (Tg), hardness, and solubility. It is often stabilized with inhibitors like 4-methoxyphenol (MEHQ) to prevent premature polymerization during storage and transport, a detail that a chemical supplier will always provide.

Synthesis and Manufacturing Overview

The industrial synthesis of Cyclohexyl Acrylate typically involves the esterification of acrylic acid with cyclohexanol. This reaction is commonly catalyzed by strong acids, such as sulfuric acid or p-toluenesulfonic acid, often with the removal of water formed during the reaction to drive the equilibrium towards product formation. Manufacturers employ various techniques to ensure high yields and purity, including distillation under reduced pressure to separate the desired ester from unreacted starting materials, by-products, and catalysts. The quality of the raw materials and the precision of the manufacturing process are critical determinants of the final product’s purity. Companies seeking to buy Cyclohexyl Acrylate should inquire about the synthesis process and the quality control measures employed by their potential suppliers.
