A. Cesana et al., A STUDY OF THE ORGANIC BY-PRODUCTS IN THE CYCLOHEXANONE AMMOXIMATION, Journal of molecular catalysis. A, Chemical, 117(1-3), 1997, pp. 367-373
The heterogeneous catalyzed ammoximation of cyclohexanone on titanium
silicalite catalyst has been studied. Cyclohexanone oxime is formed by
reaction of cyclohexanone with ammonia and hydrogen peroxide. The org
anic by-products formed in the reaction have been studied and the foll
owing products were identified: nitrocyclohexane, cyclohexenylcyclohex
anone, cyclohexenone oxime and cyclohexanone azine. The effect of some
reaction parameters on by-products formation have been investigated.
Experiments have been performed to verify if these by products are due
to side or consecutive reactions and derive from non-catalyzed or cat
alyzed reactions.
