2-Hydroxyethyl acrylate
Low-Temperature Fluidity: The compound maintains liquid state at cryogenic conditions due to its melting point of -70°C, ensuring operational functionality across diverse thermal environments.
Solubility Profile: It demonstrates complete miscibility with aqueous systems and organic solvents, supporting versatile implementation in chemical processing and industrial formulations.
Polymerization Stabilization: Incorporation of 400 ppm hydroquinone monomethyl ether as an inhibitor effectively suppresses spontaneous polymerization during storage and handling operations.
Safety Characteristics: The material exhibits enhanced handling safety through its elevated flash point (104°C) and minimal vapor pressure, maintaining stability under standard storage conditions.
This chemical product is a colorless liquid characterized by a low melting point of -70°C. Its boiling point demonstrates pressure-dependent variation, measuring 90-92°C at 1.6 kPa and 74-75°C at 667 Pa. The liquid possesses a relative density of 1.1098 at 20°C and a refractive index of 1.4. With an open-cup flash point of 104°C, the substance presents relatively low flammability risk under standard handling conditions. The measured viscosity of 5.34 mPa·s at 25°C indicates favorable flow characteristics, supporting its utility in applications requiring enhanced fluidity.
