Synthesis and Structural Characterization of Diisobornyl Oxalate
摘要
Abstract
Diisobornyl oxalate was obtained by rearrangement,addition and esterification reactions from camphene and oxalic acid with boric anhydride as catalyst. The effects of reaction conditions such as material ratio,dosage of catalyst,reaction temperature and reaction time on the conversion of camphene and the selectivity of diisobornyl oxalate were explored. The results showed that the optimal synthetic conditions were:the mass ratio of camphene,anhydrous oxalic acid and catalyst 1. 7∶2∶1,reaction time 96 h,and reaction temperature 55 ℃. Under these conditions,the conversion rate of camphene was 89. 5% and the selectivity of diisobornyl oxalate was 95. 6%. The structure of diisobornyl oxalate was characterized by IR, LCMS-IT-TOF, 1H NMR and 13C NMR.关键词
