Green synthesis process for bornyl alcohol

The invention discloses a green synthetic method for borneol. The method comprises the following steps of: placing alpha-pinene, anhydrous oxalic acid and a catalyst of zirconium sulfate into a reaction bulb and heated with stirring to a temperature of between 40 and 150 DEG C to conduct an esterification reaction, after the esterification reaction lasts for 1 to 10 hours, the mixture is filtered to reclaimed the catalyst; the filtrate undergoes the removal of light oil to obtain a dicamphor oxalate, and a sodium hydroxide solution is added into the dicamphor oxalate to carry out a saponification reaction, a reaction product is collected while distillation is performed, and the product is borneol. The method has the advantages that the reaction is stable, the operation is safe, the catalyst is readily available, the preparation is simple and convenient, the raw materials can be used by only burning and crushing, the catalyst can be easily separated from the reaction product by filtration, no correction is caused to equipment, no pollution is caused to environment, and the catalyst is reusable, activable and renewable, with strong catalytic activity, and the selectivity of the reaction is excellent.
