In the field of chemical production raw materials, AA (acrylic acid) is an important organic compound and has a wide range of applications. AA has many upstream and downstream related products, and some of the main upstream and downstream products will be described in detail below.

1. the upstream products of AA

1. Propylene: Propylene is the main raw material of AA and produces acrylic acid through oxidation reaction. The supply of propylene has an important influence on the production cost and market price of AA.
2. Catalyst: In the production process of AA, a catalyst is needed to improve reaction efficiency and selectivity. Commonly used catalysts include oxides or salts of metals such as molybdenum, vanadium, and antimony.
3. Oxidizing agent: The oxidizing agent is used to oxidize propylene to produce acrylic acid, and the commonly used oxidizing agents include air, oxygen, etc.

2. AA downstream products

1. Acrylate: Acrylic acid can react with alcohols to generate acrylate, common acrylate products include methyl acrylate, ethyl acrylate, butyl acrylate, etc. These ester products are widely used in coatings, adhesives, plastics and other fields.
2. Polymer: Acrylic acid can be used as a monomer and copolymerized with other monomers to form a polymer. For example, acrylic acid and styrene are copolymerized to form an acrylic styrene copolymer (ASA), which has excellent weather resistance and heat resistance and can be used in outdoor buildings, automobile parts, etc.
3. Water treatment agent: Acrylic acid and its salts can be used as a water treatment agent for adjusting the pH value of water, removing metal ions, etc.
4. Paper coating agent: Acrylic emulsion can be used as a paper coating agent to improve the surface performance and printing performance of paper.

In conclusion, AA, as an important organic compound, has a wide range of applications in the field of chemical production raw materials. Its upstream and downstream related products are numerous, involving coatings, adhesives, plastics, polymers, water treatment agents and other fields.
