Properties | Sevobutyric acid is also called perfluorobutyric acid. It is a colorless liquid at room temperature, smells like butyric acid, and has strong acidity. Perfluorobutyric acid has stable properties and can generate salt reaction, esterification reaction, substitution reaction, dehydration reaction and reduction reaction of alcohol hydroxyl group. |
use | perfluorobutyric acid and its derivatives are a class of chemical intermediates, which can be used as new medicine, gunpowder, perfume intermediates, as well as raw materials or additives for the synthesis of new organic polymer materials, and at the same time, they can also be used as organic solvents. Derivative reagents for the detection of aminoglycoside antibiotics. Ion pair reagents, protein sequencing. |
preparation | industrial perfluorobutyric acid is prepared by electrochemical fluorination method, butyyl chloride is used as the starting material, and anhydrous hydrogen fluoride occurs electrolytic fluorination reaction, and the anode product is neutralized and acidified to obtain the product. |
