Paraformaldehyde is an important raw material for chemical production, which is widely used in many fields. In the upstream and downstream industry chain of paraformaldehyde, related products are rich and diverse. This article will detail the upstream and downstream associated products of paraformaldehyde.
1. upstream associated products
1. Formaldehyde
paraformaldehyde production mainly formaldehyde as raw material, through polymerization reaction. Therefore, formaldehyde is the main upstream associated product of paraformaldehyde.
2. Methanol
Methanol is an important raw material of formaldehyde, which can be produced by oxidation reaction. Therefore, methanol is also one of the upstream associated products of paraformaldehyde.
2. downstream associated products
1. phenolic resin
paraformaldehyde can react with phenol and other phenolic substances to produce phenolic resin. Phenolic resin has excellent heat resistance, corrosion resistance, dimensional stability and other characteristics, widely used in FRP, coatings, abrasives and other fields.
2. urea formaldehyde resin
paraformaldehyde and urea reaction can generate urea formaldehyde resin. Urea-formaldehyde resin has good bonding performance and water resistance, and is commonly used in wood processing, construction, coatings and other industries.
3. melamine formaldehyde resin
the reaction of paraformaldehyde and melamine can be prepared melamine formaldehyde resin, also known as melamine resin. This resin has good heat resistance, water resistance, electrical insulation and other characteristics, can be used in the manufacture of tableware, electrical parts and so on.
4. pentaerythritol formaldehyde resin
paraformaldehyde and pentaerythritol reaction can generate pentaerythritol formaldehyde resin, also known as four hydroxymethyl methane formaldehyde resin. This resin has good heat resistance, water resistance, corrosion resistance and other characteristics, can be used in the manufacture of paint, coating and so on.
In short, paraformaldehyde has a wide range of upstream and downstream related products, involving many fields, such as chemical industry, building materials, wood processing, etc. Understanding these related products will help to better understand the important position and application value of paraformaldehyde in the field of chemical production raw materials.
