Process flow of methyl acrylate
Methyl acrylate process flow: Methyl acrylate is an important organic chemical widely used in coatings, adhesives, resins, and other fields. The production process generally includes steps such as raw material preparation, esterification reaction, alcoholysis reaction, and distillation separation.Firstly, the raw material preparation stage requires the preparation of acrylic acid and methanol. Acrylic acid is usually produced through catalytic hydrogenation, while methanol is a common industrial chemical. The quality and purity of these two raw materials will directly affect the subsequent esterification reaction and product quality.
Esterification reaction is a crucial step in the production of methyl acrylate. In the reaction vessel, add acrylic acid and methanol together with the catalyst and heat and stir. Under appropriate temperature and pressure conditions, the reaction will occur, producing methyl acrylate and water. This is a reversible reaction that requires controlling the reaction conditions to improve yield and purity.
The next step is the alcoholysis reaction, which is used to remove the generated water. The upcoming alcoholysis reaction produces methyl acrylate, which reacts with excess methanol to produce methyl acrylate and water. This step is mainly to improve the purity of the product and remove impurities and moisture.
Finally, there is the distillation separation process. Send the reaction product into the distillation tower, evaporate it by heating, and then condense to separate the target product from impurities. This step will further improve the purity and yield of the product.
Through the above process flow, we can obtain high-purity methyl acrylate products. Of course, in industrial production, energy consumption, waste disposal, and safety production issues also need to be considered to ensure efficient, economical, and safe production throughout the entire process.
