Y is a conjugated |pi~-linker including aryl, vinyl, or ethynyl groups or combinations thereof, and mes is the mesityl group, 2,4,6-|Me.

Celanese's Cangrejera plant will continue to produce other products including acetic anhydride, ethyl acetate, methylamines, acetone derivatives, and mesityl
oxide to meet customer commitments in Mexico and other countries.
of acetone to diacetone alcohol with the subsequent dehydration of the diacetone alcohol to yield mesityl oxide over an acidic ion exchange resin catalyst.
The mesityl oxide/water binary is an excellent example as it is a heterogeneous azeotrope.
