NOVELTY - Resource utilization of canthaxanthin heterogeneous filter mother liquor involves taking isomerous filtering mother liquor containing canthaxanthin over-oxidizing impurity as reaction substrate, subjecting to deoxidizing and reducing reaction, under the action of modified catalyst and reducing agent to obtain product. USE - Method for resource utilization of canthaxanthin heterogeneous filter mother liquor. ADVANTAGE - The method improves the total yield of the heterogeneous reaction, and reduces the waste liquid production amount.
