Hydroxypropyl Acrylate HPA Preparation Methods
Reaction of Sodium Acrylate with ChloropropanolThe product synthesized by this method has a low yield and very unstable quality.
Reaction of Acrylic Acid with Propylene OxideThe main route for synthesizing hydroxypropyl acrylate at home and abroad is the reaction of acrylic acid and propylene oxide under a catalyst. The selection of the catalyst is the core of this synthesis research. At the same time, due to the difficulty of current catalyst methods in achieving high-yield and high-quality hydroxypropyl acrylate HPA in industrialization, preparation has become difficulty.
