Hydroxypropanedioic acid - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Overview | tartaric acid is a high value-added chemical that is widely used in the pharmaceutical field, it can inhibit the conversion of carbohydrate into fat in the human body, prevent the accumulation of fat in the body, and has the effect of losing weight and preventing coronary heart disease. |
| pharmacological studies | Modern pharmacological studies have shown that cucumber fruit contains tartaric acid, which can prevent the accumulation of fat in the human body, have the effect of weight loss and prevention of coronary heart disease. The astringent taste of Cucumber mainly comes from tartaric acid contained in cucumber, which is not contained in other common vegetables. The fusion of tartaric acid and saliva has a slightly astringent taste. |
| Use | for organic synthesis. |
| production method | using diethyl malonate as a raw material, bromine is first added under illumination, and diethyl malonate bromide is distilled under reduced pressure to obtain diethyl malonate bromide. Potassium hydroxide solution was then added, hydrolyzed by heating at reflux for 4H and neutralized to pH 5 with acetic acid. Barium chloride solution was added to form barium hydroxymalonate. After acidification, it was distilled under reduced pressure, extracted with ether, and finally refined with acetic acid to obtain a finished product. |
