Question

BDC reaction with ethanol then products formed are?

Answer 1

Diethyl terephthalate

Answer 2

Solution:

The term “BDC” in many MOF‐synthesis contexts stands for the benzene dicarboxylate (specifically, the terephthalate or benzene‐1,4–dicarboxylate) group. When benzene–1,4–dicarboxylic acid (terephthalic acid) reacts with ethanol under typical esterification conditions (acid catalysis, reflux), both –COOH groups are converted into –COOEt groups. This produces the diester known as diethyl terephthalate along with water as a by‐product.

The overall reaction is:

$$\text{HOOC–C}_6\text{H}_4–\text{COOH} + 2\,\text{EtOH} \xrightarrow{\text{acid, heat}} \text{EtOOC–C}_6\text{H}_4–\text{COOEt} + 2\,\text{H}_2\text{O}$$

Core Explanation (minimal):

1. BDC refers to benzene–1,4–dicarboxylate (terephthalic acid).

2. Under acid‐catalyzed esterification with ethanol, both –COOH groups form –COOEt.

3. The product is diethyl terephthalate.
