Methanol is an important organic chemical raw material, which is widely used in the production of various chemicals and fuels. In the field of chemical production raw materials, the upstream and downstream related products of methanol are very rich. Methanol and its downstream upstream and downstream associated products will be described in detail below.

1. methanol upstream product

1. Natural gas

Natural gas is one of the main raw materials for methanol production, through the oxidation of methane in natural gas to generate synthesis gas (CO H2), and then through the synthesis reaction made of methanol.

2. Coal

Coal is also one of the important raw materials for methanol production. Syngas is generated through coal gasification, and then methanol is generated through synthesis reaction.

3. Heavy oil

heavy oil can also be used to produce methanol, through the partial oxidation of heavy oil to generate synthesis gas, and then through the synthesis reaction to make methanol.

2. methanol downstream products

1. Formaldehyde

Formaldehyde is one of the main products of methanol downstream, used in the production of phenolic resin, urea-formaldehyde resin, melamine formaldehyde resin and other adhesives, but also used in the production of dyes, pharmaceuticals, pesticides and so on.

2. Acetic acid

Acetic acid is one of the important products in the downstream of methanol. It is used in the production of acetate fiber, acetate, acetate and other chemicals, as well as in the production of pesticides and medicines.

3. Dimethyl ether

Dimethyl ether is one of the downstream products of methanol. It has clean and efficient characteristics and can be used to replace liquefied petroleum gas (LPG) and coal gas and other fuels.

4. MTBE

MTBE is a gasoline additive that can increase the octane number of gasoline and improve the performance of gasoline. MTBE is one of the products downstream of methanol.

5. olefin

methanol can be produced by dehydration reaction of olefins, such as ethylene, propylene, etc., these olefins are important organic chemical raw materials, can be used in the production of various plastics, rubber, fiber, etc.

3. the application of methanol and its downstream products

methanol and its downstream products have a wide range of applications in various fields, the following are a few specific examples:

1. construction field

methanol downstream of formaldehyde, acetic acid and other products can be used to produce a variety of adhesives and coatings, widely used in the construction field.

2.

in the automotive field Methanol can be used as fuel for automobiles, and can also be used for the production of automobile tires, rubber products, etc. At the same time, products such as MTBE downstream of methanol can also be used as gasoline additives to improve the performance of gasoline.

3. pharmaceutical field

methanol downstream of many products, such as acetic acid, olefins, etc., can be used to produce a variety of drugs and medical equipment.

In short, methanol and its downstream products have an important position in the field of chemical production raw materials and are widely used in various fields.
