As an important chemical raw material, formaldehyde is widely used in various fields. In the field of chemical production raw materials, there are many upstream and downstream related products of formaldehyde, and some of the main products will be described in detail below.

1. upstream product

1. methanol

formaldehyde production mainly methanol as raw material, through oxidation or dehydrogenation reaction. Therefore, methanol is the main upstream product of formaldehyde.

2. natural gas

part of formaldehyde manufacturers will also use natural gas as raw material, through the steam reforming reaction to produce synthesis gas, and then further synthesis of formaldehyde.

2. downstream product

1. Phenolic resin

Phenolic resin is an important thermosetting resin with excellent heat resistance, corrosion resistance, electrical insulation and dimensional stability. Formaldehyde and phenol react under acidic conditions to produce phenolic resin, so formaldehyde is one of the important raw materials of phenolic resin.

2. Urea-formaldehyde resin

Urea-formaldehyde resin is a commonly used adhesive, with high bonding strength, good water resistance, low price and other advantages, widely used in wood processing, construction, automotive and other fields. Formaldehyde and urea react under alkaline conditions to produce urea-formaldehyde resin, so formaldehyde is also one of the important raw materials of urea-formaldehyde resin.

3. Melamine formaldehyde resin

Melamine formaldehyde resin is a thermosetting resin with excellent heat resistance, water resistance, electrical insulation and mechanical properties. It is widely used in wood processing, coatings, fabric treatment and other fields. The melamine formaldehyde resin is prepared by the reaction of formaldehyde and melamine under acidic conditions, so formaldehyde is also one of the important raw materials of melamine formaldehyde resin.

4. 1,3-Butadiene

Formaldehyde can also be prepared by the addition reaction of acetylene and formaldehyde under acidic conditions to produce 1,3-butadiene, which is an important chemical raw material and can be used in the production of synthetic rubber, synthetic fiber and other fields.

In conclusion, formaldehyde has a wide range of upstream and downstream related products in the field of chemical production raw materials and has important application value.
