Acrylic acid catalyst
Highly selective catalytic solution for the two-stage oxidation of propylene to produce acrylic acid
Description
marker
▎Product overview
The acrylic acid catalyst is designed for key oxidation steps in the acrylic acid production process. In industry, acrylic acid is produced according to a two-stage scheme: first, propylene is oxidized to acrolein, which is then oxidized to acrylic acid. In this regard, the description of the catalyst should emphasize “sequential reactions, increasing selectivity and preventing overoxidation.” The industrial production of acrylic acid is based precisely on two-stage oxidation with acrolein as an intermediate product.
▎Process description
In the technological chain for the production of acrylic acid, the first stage is the conversion of propylene into acrolein, the second is the further oxidation of acrolein to acrylic acid. The description should emphasize that the key objective of the process is not the fact that the reaction occurs, but the ability to prevent overoxidation, provide high selectivity and stability in continuous production.
▎Key Benefits
• Optimized for two-stage oxidation process
• Emphasis on efficient conversion of the intermediate acrolein
• Control the risk of overoxidation
• Suitable for continuous industrial installations
• Helps increase the overall yield of the target product
▎Main technical characteristics
• Selectivity for acrylic acid
• Acrolein conversion
• Control of by-product formation
• Heat management ability
• Layer stability
• Service life
▎Typical Applications
• Acrylic acid production plants
• Raw material chain for the production of acrylic acid esters
• Upper stage for water-based coatings and adhesives
• Production of fine organic synthesis carboxylic acids
This is an industrial catalytic technology focused on “efficient deep oxidation of the intermediate acrolein” rather than a one-step direct conversion.
▎Frequently Asked Questions
Question: Why is it important to emphasize two-step oxidation for acrylic acid production catalyst?
Answer: Because the industrial route for the production of acrylic acid involves first the formation of acrolein, and then its oxidation to acrylic acid, and the description must clearly reflect this technological route.
