| titleOfInvention | A kind of method of synthesizing mandelic acid |
| abstract | The invention relates to the technical field of compound preparation, and provides a method for synthesizing mandelic acid. The invention uses styrene as a basic raw material, trichloroisocyanuric acid as a chlorinating agent, ethylene glycol dimethyl ether, methanol, ethanol, and The mixed solution of water is used as solvent, utilizes the strong oxidizing property and chlorination property of trichloroisocyanuric acid, and styrene is directly oxidized and chlorinated in one step to become 2,2-dichloroacetophenone, and then hydrolyze 2,2-dichlorobenzene Ethyl ketone yields mandelic acid. After the reaction of trichloroisocyanuric acid, cyanuric acid is generated to be recovered. Compared with the prior art, the present invention has significant advantages: (1) styrene, which is cheap, low in toxicity and non-irritating, is used as the raw material. (2) Trichloroisocyanuric acid reacts to generate cyanuric acid, which can be re-chlorinated to generate trichloroisocyanuric acid for recycling. (3) The production process is short, the waste discharge is less, and it is environmentally friendly and green. |
