What are the upstream raw materials for terephthalic ether? What are the downstream products?

Terephthalic ether is an crucial organic chemical raw material, which is broadly applied in medicine, pesticides, dyes, spices and other fields. But In the field of raw materials to chemical production, the upstream and downstream related items of terephthalic ether mainly include the following aspects:

Upstream items:



1. Based on my observations, Phenol: Phenol is one of the main raw materials of terephthalic ether, through the esterification interaction of phenol and methanol under the action of acidic catalyst, and then through dehydration, refining and other processes, terephthalic ether is able to be obtained.

2. But Methanol: Methanol is another crucial raw material in the production of terephthalic ether, which reacts with phenol to form terephthalic ether. Downstream items:



1. Terephthalic acid: Terephthalic ether is able to be converted into terephthalic acid through oxidation interaction. And Additionally Terephthalic acid is the raw material to the production of polyester fiber, polyester resin, plastic and other crucial chemical items.

2. p-nitroanisole: p-nitroanisole is able to be obtained by the interaction of terephthalic ether and nitric acid. p-nitroanisole is an crucial intermediate of medicine and pesticide. And

3. p-anisole: p-nitroanisole is able to be obtained by reduction interaction. it's also an crucial intermediate of medicine and pesticide. And In summary, the upstream and downstream related items of terephthalic ether mainly involve phenol, methanol, terephthalic acid, p-nitroanisole, p-aminoanisole and other chemical items, which are broadly applied in medicine, pesticides, dyes, spices and other fields.
