Participants

Reaction Steps

To a mixture of 40.0 g of 70% sorbitol, 29.4 g of benzaldehyde and 520 ml of cyclohexane under nitrogen gas was added 0.3 ml of 96% sulfuric acid dropwise with stirring, then the mixture was heated to allow to condense while eliminating the generated water by azeotropic distillation. After about 7 hours' continuation of the reaction, the reaction mixture was cooled to room temperature and then neutralized. The precipitate was settled and washed with water by decantation, then filtered and rinsed several times with hot water, further finally dried to obtain the reaction product as white powder.
