Isobutanol is an important organic chemical raw material, widely used in medicine, pesticides, plastics, spices and other fields. In the field of raw materials for chemical production, the upstream and downstream related products of isobutanol mainly include the following aspects:

upstream products:

1. Propylene: Propylene is one of the main raw materials of isobutanol, and isobutanol can be produced through the hydration reaction of propylene.

2. Syngas: Syngas (a mixture of CO and H2) can also be used to produce isobutanol by reacting CO and H2 in the syngas to produce isobutyraldehyde, which is further hydrogenated to produce isobutanol.

downstream products:

1. Methyl methacrylate (MMA): Isobutanol can be used as one of the raw materials for the production of MMA. Methacrolein is generated by the reaction of isobutanol and formaldehyde, and then further oxidized to form MMA.

2. Isobutyl acetate: Isobutyl alcohol reacts with acetic acid to produce isobutyl acetate, which is an important solvent and fragrance.

3. Butanone: Isobutanol can be dehydrogenated to produce butanone, which is a solvent and an intermediate in organic synthesis.

4. Isobutyraldehyde: Isobutanol can also be oxidized to generate isobutyraldehyde. Isobutyraldehyde is an important organic synthesis intermediate, which can be used to produce drugs and pesticides.

In short, isobutanol plays an important role in the field of chemical production raw materials, and its upstream and downstream related products are extensive, which can promote the development of many fields.
