N2 - The acetoxylation of alpha-pinene was carried out over SBA-15 with sulfonic acid groups. The products of acetoxylation of alpha-pinene are acetates (alpha-terpinyl acetate, bornyl acetate and beta-fenchyl acetate) and hydrocarbons (camphene, tricyclene, limonene, gamma-terpinene, terpinolene and alpha-terpinene). Catalysts with different amount of sulfonic acid groups were prepared. It was observed that the activity increases with increase of the surface area and porous volume. Catalytic stability of the sample that showed the highest activity (C1) was evaluated by performing consecutive batch runs with the same catalyst sample. After the fifth batch, the catalyst exhibited a good initial activity.
