| Abstract: | Dibenzylidene sorbitol( DBS) was synthesized and puried using orthogonal experiment method ,The optimum condition as follows: the mole proportion of benzaldehyde and sorbitol is 2.2∶1.0, the volume proportion of cyclohexane and methanol is 70∶30, and rate of mix round 450rpm,reaction time 5 h, in this condition, DBS was purified in the mixture of cyclohexane and propanone, and highpurity DBS was gotten, the recovery rate was 82.9%. |
