What is 1,3-Dimethylbarbituric acid?
With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is 1,3-dimethylbarbiturates which has developed particularly rapidly in recent years. Do you know about 1,3-dimethylbarbiturates?
The official answer: 1,3-Dimethylbarbituric acid is a white or light yellow crystal, soluble in ethanol, melting point 121-123℃, is an important chemical intermediate, widely used in the chemical and pharmaceutical industries.
What’s the application of 1,3-Dimethylbarbituric acid?
1,3-dimethylbarbiturates and chlorinating agent are reacted with reflux in an organic solvent insoluble with water to obtain the reaction mixture; after quenching the reaction with water, 6-chloro-1,3-dimethyluracil is obtained; said chlorinating agent includes trichloroxaphor. The preparation method provided by the present invention reduces the use of phosphorus trichloride and eliminates the need to distill phosphorus trichloride under reduced pressure. Further, the present invention allows the addition of additives during the reaction, which can improve the yield of 6-chloro-1,3-dimethyluracil. The present invention also provides a method for synthesizing 1,3-diethyl barbituric acid, where 1,3-dimethyluracil, dimethyl malonate, and condensation agent are reacted in the organic solvent to obtain 1,3-diethyl barbituric acid, avoiding the use of large amounts of malonic acid and acetic anhydride.
