Chemical Formula	C3H6O2
Molecular Weight of Methyl Acetate (C3H6O2)	74.079 g/mol
Density of Methyl Acetate	0.932 g/cm3
Melting Point of Methyl Acetate	−98 °C
Boiling Point of Methyl Acetate	56.9 °C

It is prepared by condensation of Acetic Acid with Methanol. Hydrogen in Acetic acid is replaced with a methyl group and it forms Methyl acetate. In the presence of strong acids or strong bases, the methyl acetate is hydrolyzed and forms back Acetic acid and Methanol.

Structure of Methyl Acetate (C₃H₆O₂)

Methyl Acetate Structure is added in the image below,

There are ten sigma (σ) bonds and one pi (π) bond in Methyl Acetate. The C–C–O bond of carbonyl carbon has a bond angle of 111.2°, whereas the O–C–O bond has a bond angle of 123.2°. In methyl acetate, the ester function group is flexible and spins around the C–O–C bond. Methyl acetate becomes less rigid and more volatile as a result of this flexibility.

Methyl Acetate Formula

Chemical formula for Methy Acetate is, C₃H₆O₂

Preparation of Methyl Acetate (C₃H₆O₂)

Heating of Methanol (Methyl alcohol) with Acetic Acid in the presence of Sulphuric Acid produces Methyl Acetate. Here, sulphuric acid acts as a catalyst. The reaction for the same is added below,

CH₃COOH + CH₃OH + H⁺   ↔   CH₃COOCH₃ + H₂O

This reaction is also called as, Eastrification Reactions

Production of Methyl Acetate

• Metyl Acetate in industrial level is prepared by Carbonylation of Methanol in which Methyl Acetate is byproduct of synthesis of Acetic Acid.
• Esterfication is also and imporatnt method in production of Methyl Acetate.

Methyl Acetate-Fcolourlessequently Asked Questions

What is Difference between Methyl Acetate and Acetone?

Methyl acetate, unlike acetone, has a mild odour, making it perfect for usage in furniture and automobiles. Methyl acetate may also be found in cosmetics like fragrances and nail paint removers, and it causes less harm to the nails than acetone.

What is Functional Group of Methyl Acetate?

Methyl acetate has Ester functional group. Symbol for ester is RCOOR′.

Can Methyl Acetate form Hydrogen Bonds with Water?

Methyl Acetate did not form hydrogen bonding with water since it lacks -OH bond.

How is Methyl Acetate Produced?

Methyl Acetate can easily be produced by Eastrification Reaction.

What is Name of C₃H₆O₂?

Name of C₃H₆O₂ is Methyl Acetate.
