2-Methylacrolein (2-MAL) is an important organic chemical raw material, which is widely used in fine chemicals, polymer materials, medicine and other fields. The following are the upstream and downstream related products of 2-methacrolein:

upstream products:

1. Propylene: Propylene is the main raw material of 2-methacrolein, which generates 2-methacrolein through oxidation reaction.

downstream products:

1. 2-methacrylic acid (Methacrylic acid, referred to as MAA):2-methacrolein can be converted to 2-methacrylic acid by adding water reaction, which is an important polymer monomer, Used in the production of methyl methacrylate (MMA) and other polymers.
2. Methyl Methacrylate (MMA):2-methyl methacrylate is a transparent, high hardness, high toughness plexiglass material, widely used in construction, automotive, electronics and other fields.
3. 2-methacryl alcohol (2-Methyl-3-buten-2-ol): 2-methacrolein can be converted to 2-methacryl alcohol by hydrogenation reaction, which is an important fragrance and fine chemical intermediate.
4. 2-Methylacrylamide (2-Methylacrylamide): 2-Methacrolein can react with ammonia to obtain 2-methacrylamide, which is a water-soluble polymer monomer used in the production of sewage treatment agents, paper enhancers, etc.

In short, as an important organic chemical raw material, 2-methacrolein has a wide range of upstream and downstream related products, involving polymer materials, fine chemicals, medicine and other fields.
