Applicazioni

Mesitylene is used to make plastics and dyes. It acts as a solvent, ligand in organometallic chemistry and precursor to 2,4,6-trimethylaniline. It is also used as a developer for photopatternable silicones due to its solvent properties in the electronics industry. It is used as an internal standard in nuclear magnetic resonance (NMR) samples due to the presence of three equivalent protons in it. It is involved in the production of trimesic acid and antioxygen, epoxy firming agent and polyester resin stabilizers. Further, it is used as an additive and component in aviation gasoline blends.

Note

Incompatible with strong oxidizing agents.

Letteratura

The Adams modification of the Gattermann reaction for aromatic formylation by reaction with Zinc cyanide, L15836 , and HCl is exemplified: Org. Synth. Coll., 3, 549 (1955). The Vilsmeier formylation (see N,N-Dimethyl­formamide, A13547 ), has been extended to less activated substrates, including mesitylene, by use of the combination of DMF and triflic anhydride: J. Chem. Soc., Chem. Commun., 1571 (1990).

For conversion to mesitoic acid by Friedel-Crafts reaction with oxalyl chloride, and aqueous work-up, see: Org. Synth. Coll., 5, 706 (1973).
