Ionone synthesis (α, β and γ isomers) by PSEUDOIONONE (cas 141-10-6) cyclization was studied on zeolite HBEA, Amberlyst 35W, SiO2–Al2O3, and unsupported and silica-supported heteropolyacids (HPA/SiO2). Ionone formation was preferentially promoted on strong Brønsted acid sites. A 79% ionone yield was obtained on 58.5 wt.% HPA/SiO2 after 1.5 h of reaction at 383 K and 250 kPa. This value is similar to the best yields reported for the homogeneously-catalyzed reaction using sulfuric acid.
