| 发明名称 | Production of aldehydes by oxidation in aqueous medium with selective recovery of the product by means of pervaporation | ||
| 摘要 | A process for the preparation of an aromatic aldehyde by means of the oxidation of the corresponding starting compound in aqueous medium, and separation of said aldehyde from said medium by pervaporation is disclosed together a plant for its carrying out. Advantageously, the process of the present invention allows control of oxidation reaction and recovery of the product with high selectivity and purity. Among others, benzaldehyde, anisaldehyde and vanillin can advantageously be prepared by this process. | ||
