| titleOfInvention | Preparation and recovery method of 2-methyl-5-iodobenzoic acid |
| abstract | The invention provides a preparation and recovery method of 2-methyl-5-iodobenzoic acid. The method comprises the steps: iodinating by using iodine/potassium periodate in a mixed acid solvent and taking otoluic acid as a raw material to obtain a mixture of 2-methyl-5-iodobenzoic acid, 2-methyl-3-iodobenzoic acid and 2-methyl-3, 5-diiodosalicylic acid; refining to obtain 2-methyl-5-iodobenzoic acid and a mother solution regenerant, wherein the mother solution regenerant is the mixture of 2-methyl-5-iodobenzoic acid, 2-methyl-3-iodobenzoic acid and 2-methyl-3, 5-diiodosalicylic acid; recovering otoluic acid and iodine ions through catalytic hydrogenation deiodination; oxidizing the iodine ions for recovering iodine. The whole process is circularly utilized. The preparation and recovery method has the advantages that the raw material is easy to obtain and low in price, the preparation process is simple in operation, the equipment requirement is low, and the method is suitable for large-scale industrial production. |
