2-Hydroxyethyl acrylate CAS # 818-61-1
      
                1. Low Melting Point: With a melting point of -70°C, it remains fluid in low-temperature conditions, offering versatility in various environments.
2. Versatile Solubility: Miscible with water and soluble in many organic solvents, ideal for diverse industrial and chemical applications.
3. Polymerization Control: Contains a 400 ppm inhibitor (hydroquinone monomethyl ether), preventing unwanted polymerization during storage and handling.
4. Stable and Safe: Exhibits a relatively high flash point (104°C) and low vapor pressure, ensuring safer handling and storage under normal conditions.
This product is a colorless liquid with a low melting point of -70°C, and a boiling point that varies between 90-92°C at 1.6 kPa, and 74-75°C at 667 Pa, depending on the environmental pressure. The liquid exhibits a relative density of 1.1098 at 20/4°C and a refractive index of 1.4, indicating its optical properties. Its flash point, measured in an open cup, is 104°C, meaning that it is relatively safe in terms of flammability under normal conditions. With a viscosity of 5.34 mPa·s at 25°C, it is fluid and flows easily, which makes it suitable for various applications where fluidity is important.
The product is miscible with water and is also soluble in a wide range of general organic solvents, giving it significant versatility in industrial formulations and processes. The presence of a 400 ppm inhibitor, hydroquinone monomethyl ether, helps to prevent polymerization, which can otherwise occur in certain conditions, thus ensuring stability during storage and handling. This makes it highly reliable for use in various chemical, pharmaceutical, and manufacturing processes where polymerization control is necessary.
