A novel method for determination of benzoyl peroxide with spectrophotometry was developed. Inclusion ratio of β cyclodextrin to dibenzoy peroxide and benzoic acid is obtained with spectrophotometry.The mechanism of the inclusion was studied,too. The results showed that β-CD react with dibenzoyl peroxide to form a 1:1 or 2:1 host-guest complex, with the apparent formation constants of 5.0× 10~2and 2.5× 10~4 , respectively.β-CD reacts with benzoic acid to form a 1:1 host-guest complex with the apparent formation constant of 6.9 × 10~2 after the dibenzoyl peroxide was reduced by hydroxyl ammonium chloride.

建立了用β环糊精测定过氧化苯甲酰的分光光度法，并测定了β环糊精与过氧化苯甲酰和苯甲酸的包结比，随着β-CD浓度的增大，可与BPO分别形成1：1或2：1的包容络合物，包结常数分别为5.0×10~2和2.5×10~4，与苯甲酸形成1：1的包容络合物，包结常数为6.9×10~2；由于包结物的吸光度值比过氧化苯甲酰的吸光度值大大增加，建立了一种当β-CD存在下，在水溶液中测定过氧化苯甲酰的方法。
