[Chemical Knowledge]:What are the upstream raw materials for benzoic acid? What do the downstream products contain?

Benzoic acid plays an important role in the field of chemical production raw materials, and its upstream and downstream related products are widely used. The following describes in detail the main upstream and downstream associated products of benzoic acid.

1. Upstream Products

1. Toluene

Toluene is one of the main raw materials of benzoic acid, which can be produced by oxidation reaction. The source of toluene is abundant and can be obtained from petroleum cracking, coal tar and other ways.

2. Oxygen

Oxygen is an oxidant in the production of benzoic acid, which reacts with toluene to produce benzoic acid.

2. Downstream Products

1. Sodium Benzoate

Benzoic acid and sodium hydroxide reaction can generate sodium benzoate, is a common food preservative, with the role of preventing food spoilage.

2. Ethyl benzoate

Ethyl benzoate can be generated by esterification of benzoic acid and ethanol in the presence of acid catalyst. It has a strong fruit aroma and is widely used in food additives, spices and other fields.

3. Benzaldehyde

Benzoic acid can be decarboxylated to benzaldehyde under heating conditions, which is an important organic synthesis intermediate for the production of drugs, spices, etc.

4. Phenol

Benzoic acid can generate phenol through reduction reaction. Phenol is an important chemical raw material, which is used to produce phenolic resin, bisphenol A and so on.

In short, benzoic acid has a wide range of upstream and downstream related products, involving food, medicine, chemical and other fields.
