Propylene oxide is an important organic chemical raw material, which is widely used in various fields. In the field of raw materials for chemical production, there are many upstream and downstream related products of propylene oxide, some of which are described in detail below.

1. Upstream Associated Products

1. Propylene: The main raw material of propylene oxide is propylene, which generates propylene oxide through oxidation reaction. Therefore, the price and availability of propylene have an important influence on the production of propylene oxide.

2. Hydrogen: The production of propylene oxide requires the use of hydrogen as a reducing agent, so the price and availability of hydrogen will also have an impact on the production of propylene oxide.

2. downstream related products

1. Polyether polyol: propylene oxide can react with polyol to generate polyether polyol, which is an important polyurethane foam material, which is widely used in construction, home appliances, automobiles and other fields.

2. Propylene glycol: Propylene oxide reacts with water to produce propylene glycol, which is an important chemical raw material and can be used to produce unsaturated polyester resins, plasticizers, etc.

3. dimethyl carbonate: propylene oxide reacts with carbon dioxide to generate dimethyl carbonate, which is an environmentally friendly solvent and chemical raw materials, which can be used in the production of pesticides, pharmaceutical intermediates, etc.

4. acrylic acid and esters: propylene oxide can be further oxidized to generate acrylic acid and esters, these compounds are important raw materials for the preparation of coatings, adhesives, plastics, etc.

To sum up, the upstream and downstream related products of propylene oxide are very extensive, and there are many fields involved. Therefore, in-depth study on the production, market and application of propylene oxide is helpful to better understand the development trend and future development direction of chemical production raw materials.
