Description

General description

Mesitylene, also known as 1,3,5-trimethylbenzene, is a benzene derivative. Its carbon-13 spin-lattice relaxation times, dipolar relaxation rates and nuclear Overhauser enhancements have been measured to analyze the internal methyl rotation and intermolecular interactions. The anodic oxidation of mesitylene at a platinum electrode in the presence of different electroytes has been investigated. The ring deformation in mesitylene has been studied in the gas-phase by electron diffraction.

Application

Mesitylene may be used to:

• Grow fullerene(C₆₀)/1,3,5-trimethylbenzene (mesitylene) nanowires.
• Prepare 2′,4′,6′-trimethyl acetophenone with high slectivity by reacting with acetyl chloride in the presence of dodecatungstophosphoric acid (DTP)/K-10 montomorillonite clay.
• Synthesize 3,5-dimethylbenzaldehyde from benzene via peroxidative oxidation in the presence of vanadium(IV or V) compounds with N,O-ligands as catalysts.
