Summary
-
1.
Vapor phase conversion of mesityl oxide and diacetone alcohol was studied over tricalcium phosphate.
-
2.
It was shown that like H+ and OH− ions, calcium phosphate selectively catalyzes the reaction of vapor phase hydrolytic cleavage of mesityl oxide into acetone.
-
3.
It was found that dealdolization of diacetone alcohol proceeds more completely and under more mild conditions over this catalyst than does the hydrolytic cleavage of mesityl oxide.
-
4.
The results of our work indicate that both in homogeneous catalysis and over a solid catalyst, the hydrolytic cleavage of mesityl oxide proceeds through a hydration step which limits the overall rate of the process.
