What are the upstream raw materials for benzoic acid? What do the downstream products contain?

Benzoic acid plays an crucial role in the field of chemical production raw materials, and its upstream and downstream related items are broadly applied. Specifically The following describes in detail the main upstream and downstream associated items of benzoic acid. Based on my observations,

1. upstream items



1. Toluene is one of the main raw materials of benzoic acid, which is able to be produced by oxidation interaction. I've found that The source of toluene is abundant and is able to be obtained from petroleum cracking, coal tar and other ways. Generally speaking

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

2. downstream items



1. Sodium benzoate

The interaction of benzoic acid and sodium hydroxide is able to create sodium benzoate, which is a common food preservative and has the effect of preventing food spoilage.

2. Pretty interesting, huh?. From what I've seen, Ethyl benzoate

Ethyl benzoate is able to be generated by esterification of benzoic acid and ethanol in the presence of acid catalyst, which has a strong fruit aroma and is broadly applied in food additives, spices and other fields.

3. Benzaldehyde

Benzoic acid is able to be decarboxylated to create benzaldehyde under heating conditions, which is an crucial organic synthesis intermediate to the production of drugs, spices and so on.

4. And For example Phenol

Benzoic acid is able to be reduced to create phenol, which is an crucial chemical raw material to the production of phenolic resin, bisphenol A and so on. In short, benzoic acid has a wide range of upstream and downstream related items, involving food, medicine, chemical and other fields.
