The methoxylation of alpha-pinene was studied over sulfonic acid-functionalized mesoporous silica (MCM-41, PMO) at 60 degrees C. The support functionalization was achieved by the introduction of 3-(mercaptopropyl) trimethoxysilane onto the surface of these materials either by grafting or by co-condensation. The thiol groups were oxidized to SO(3)H by treatment with H(2)O(2). All the catalysts were active in the studied reaction being the PMO-SO(3)H-g the best one. Good values of selectivity to alpha-terpinyl methyl ether were obtained with these catalysts. Catalytic stability of the PMO-SO(3)H-g was evaluated by performing consecutive batch runs with the same catalyst sample. After the third batch it was observed a stabilisation of the activity.
