Abstract: Esterification of terpineol with oxalic acid, chloroacetic acid and trichloroacetic acid by solid superacid MoO₃/TiO₂ was studied. Results showed that chloroacetic acid was the best reagent for esterification and the catalyst had satisfactory catalytic activity and selectivity. The yield of borneol and isoborneol was 52.93%, and selectivity for borneol was 60.46% at the conditions of programmed temperatures, reaction time 315 min, saponification time 1h, mass part of catalyst 5%,and terpineol:chloroacetic acid 100:25(mass ratio).

Key words: solid superacid, MoO₃/TiO₂catalyst, esterification, synthetic borneol
