Pivalic acid is an organic compound, chemical formula for C5H10O2, is an important raw material for the production of chemical products. The upstream and downstream associated products of pivalic acid are extensive, and their upstream and downstream products are described below.

Upstream Products:

1. Isobutene: Isobutene is an unsaturated hydrocarbon that can be used to prepare pivalic acid through oxidation.
2. Methanol: Methanol can be reacted with isobutylene to obtain pivalic acid, and then pivalol can be oxidized.

downstream products:

1. pivaloyl chloride: pivalic acid can react with chlorine to obtain pivaloyl chloride, which is an important organic synthesis intermediates, can be used for the preparation of pesticides, pharmaceuticals, dyes and so on.
2. pivalic acid ester: pivalic acid can be obtained by the reaction of pivalic acid with alcohols, which is a plasticizer widely used in plastics, rubber, coatings and other fields.
3. Pivalic anhydride: Pivalic acid can be obtained by dehydration reaction, which is an important raw material for organic synthesis and can be used to prepare a variety of derivatives.
4. Tepentylamine: Tepentylamine can be obtained by the reaction of pivalic acid with ammonia, which is an organic base and can be used for the preparation of catalysts, drugs, etc.

In short, the upstream and downstream associated products of pivalic acid are extensive and have important application value. In the production process, it is necessary to pay attention to safety, environmental protection and other issues to ensure product quality and production sustainability.
