Dibornyl oxalate was synthesized from esterification reaction between borneol and oxalic acid catalyzed by metatitanic acid or boron anhydrous. The effect of reaction conditions such as selectivity and dosage of catalyst, material ratio, reaction temperature and reaction time on the conversion of borneol and product selectivity of dibornyl oxalate were explored. The results showed that the optimal synthetic conditions of this reaction were: mass ratio of borneol with anhydrous oxalic acid and catalyst 5.0∶12.0∶3.0, reaction temperature 55℃ and reaction time 96 h. Under the reaction conditions, the conversion rate of borneol and the selectivity of dibornyl oxalate were 95.8% and 99.4%, respectively. The structure of dibornyl oxalate was identified and characterized by HRMS, IR, 1H NMR and 13C NMR.
