53250-83-2 - Reference Information
| Chemical properties | the product is white crystal, insoluble in water, soluble in toluene, dichloromethane and other organic solvents. |
| Use | 2-chloro-4-methylsulfonylbenzoic acid is an intermediate of the herbicides sulfonones and nitrones. used as intermediate in organic synthesis organic intermediate. |
| production method | the preparation method is to add 2-chloro-4-sulfonyl chlorobenzoyl chloride Dropwise to the aqueous solution of sodium sulfite and sodium bicarbonate at a reaction temperature of 40 ℃, reaction at the temperature of 3H, then rose to 75 deg C, then add chloroacetic acid and a small amount of sodium hydroxide, Reflux reaction at 105 deg C for 21h, cooling, acidified to pH = 1, the resulting crystals were filtered, the product was dried. Either oxidation with nitric acid with 2-chloro-4-methylsulfonyltoluene or with air in the presence of a cobalt salt as a catalyst gives the product. |
