3,3-Dimethyl-2-butanone (DIBK) is an important organic chemical raw material, which is widely used in medicine, pesticide, spice and other fields. In the field of raw materials for chemical production, the upstream and downstream related products of DIBK mainly include the following categories:

upstream products:

1. isobutylene: DIBK can be prepared by the reaction of isobutylene and formaldehyde under the action of acidic catalyst. Thus, isobutylene is an important upstream feedstock for DIBK.

2. Formaldehyde: As another important raw material for DIBK synthesis, formaldehyde reacts with isobutylene to obtain DIBK.

downstream products:

1. Pesticides: DIBK can be used as an intermediate of pesticides and is used to synthesize certain pesticides, fungicides and herbicides. For example, DIBK can be reacted with chlorine to give 3,3-dimethyl-2-chlorobutanone, which is an effective insecticide.

2. Pharmaceutical intermediates: DIBK can be used as an intermediate in the pharmaceutical industry for the synthesis of certain drugs. For example, DIBK can go through a series of reactions to produce the antiepileptic drug pregabalin.

3. Fragrances: DIBK can be used as an intermediate in the synthesis of fragrances for the preparation of certain fragrances. For example, DIBK can be reacted with benzaldehyde to give vanillin, which is a fragrance widely used in food, cosmetics, etc.

In short, DIBK, as an important organic chemical raw material, has a wide range of upstream and downstream related products, involving medicine, pesticides, spices and other fields.
