What is Diethyl Phthalate (DEP)?

Molecular Formula (Diethyl Phthalate (DEP)): C12H14O4

Molecular Weight: 222.24 g/mol

Chemical Name: Diethyl Phthalate

CAS Number: 84-66-2

It is a member of the group of phthalic acid esters known as phthalates. It belongs to the low molecular weight group, characterized by low viscosity and high volatility.

It does not have a significant odor. It is a clear, colorless liquid. It is a chemical denser than water, which is why it sinks to the bottom in water.

Its Other Names Are As Follows;

• Diethyl Phthalate
• DEP
• 84-66-2
• 1,2-Benzenedicarboxylic acid, diethyl ester
• Diethyl o-phthalate
• Diethyl Benzene-1,2-Dicarboxylate
• Phthalic Acid
• Diethyl Ester
• 1,2DEP

How is it Produced?

Its production is obtained by reacting Phthalic Anhydride with ethanol in the presence of concentrated sulfuric acid. It is then produced by careful purification in the subsequent process.

What are its Physical and Chemical Properties?
