| Application | trimethylpyruvic acid is an organic synthesis intermediate and pharmaceutical intermediate, which can be used in laboratory research and development of synthetic process and chemical biological research and development process. |
| preparation method | a synthesis process of trimethylpyruvic acid, comprising 1) Adding 250-350kg of dichloroefanone and 250-350kg of water to a reaction kettle, stir to 50? After 80 ℃, keep the temperature, add 800-1000kg of liquid alkali with concentration of 30% Dropwise within 5H, continue the reaction for 3h after adding, obtain aqueous solution containing intermediate; 2) add 200-300kg of potassium permanganate to the aqueous solution containing intermediate, during the period of 50? 60 ℃,5H added, continue the reaction for 3H, filter, collect the filtrate, adjust the filtrate pH = 1, extract the filtrate with 500kg dichloromethane to obtain the organic layer, the organic layer was distilled to 100 ℃ under atmospheric pressure, the temperature was cooled to 40 ° C., and 280-320kg of petroleum ether was slowly added, and the reaction was stirred at 5-10 ° C. For 5h, and centrifuged to obtain the product. |
| Use | 3, 3-dimethylbutanoic acid is an intermediate of the herbicide profezin. |
| production method | the preparation method is to add dichlorocyclocyanone into the reaction kettle, and then add water and a certain amount of alkali solution, heating hydrolysis under dilute alkali aqueous solution to produce sodium 3, 3-dimethyl-2-hydroxybutyrate, and then adding sodium hypochlorite solution Dropwise, oxidizing at low temperature and in the presence of catalyst, the 2-hydroxy group is oxidized to 2-oxygen, and after the oxidation is completed, the catalyst is filtered off, and the resulting filtrate, sodium 3, 3-dimethylbutanone, is further acidified to obtain a finished product. |
