- W2392889421 abstract "2,3-epoxypinane was synthesized from α-pinene by epoxidation with high selectivity.Effects of concentration and dosage of peracetic acid,dosage of anhydrous sodium carbonate,solvent types,reaction temperature and reaction time on the conversion of α-pinene were investigated,respectively.Mean while the selectivity of 2,3-epoxypinane and chemical compositions of the products were investigated too.The most suitable reaction conditions were finally determined as follows: temperature 0-10 ℃,concentration of peracetic acid 2.0 mol/L,molar ratio of α-pinene and peracetic acid 1∶1.1,molar ratio of α-pinene and Na2CO3 1∶1.2,reaction time 2.0 h,using CHCl3 as the solvent and volume ratio of α-pinene and CHCl3 1∶1.7.At this condition,conversion rate of α-pinene was above 99%,selectivity of 2,3-epoxypinane was more than 95%.The contents of the main impurities α-campholenic aldehyde and 3-pinonic in the final product were only 3.3% and 1.2% respectively." @default.
