Application
Ethyl Acrylate, stabilized with MEHQ, serves a vital role in various industrial and chemical applications due to its unique properties. As a colorless liquid with a sharp, acrid odor, it is sparingly soluble in water but readily mixes with alcohol and oils, making it highly versatile. Its ability to polymerize easily when exposed to air, heat, or daylight is carefully controlled by stabilization with MEHQ, ensuring safety and stability during handling and storage. Below 10℃, Ethyl Acrylate remains stable, but it is primarily valued for its ability to form a transparent, resilient, and odorless polymer. This compound is predominantly produced for use in paints, textiles, and non-woven fibers and also acts as a crucial reagent in synthesizing various pharmaceutical intermediates.
