| Introduction | 4-Bromobenzoic acid, also known as P-bromobenzoic acid, is a white or light pink crystal. 4-bromobenzoic acid is an important fine chemical and can be used as a perfume raw material, an intermediate of 4-bromobenzoate, a standard for measuring strontium, carbon, hydrogen and bromine by organic microanalysis. |
| Application | 4-bromobenzoic acid is an important fine chemical used as an analytical reagent and an intermediate in organic synthesis, it is used in organic synthesis and is an intermediate of dyes and medicines. |
| preparation | phase transfer catalytic synthesis of p-bromobenzoic acid: P-bromotoluene, Catalyst TEBA, turn on the reflux condensate and stirrer. Water bath heating, when the water bath temperature rises to a certain temperature, add potassium permanganate to the three-necked flask in batches, after adding, temperature control reaction time is about 2.5 h, after the reaction is finished, take advantage of hot Suction filtration, the precipitate formed in the reaction is removed. The filter cake was washed twice with boiling water, and the washing solution was combined with the filtrate. If the color of the liquid is purple, add ethanol, heat the potassium permanganate decomposition, filtration, washing. The combined filtrate was concentrated, cooled and acidified by adding 50% sulfuric acid, and a white precipitate appeared. After cooling, the filter cake was filtered, washed with cold distilled water, and put into an infrared constant temperature drying oven for drying, weighing. Melting Point: 251~256 ℃. |
| Use | organic synthesis. Determination of strontium. Organic microanalysis for the determination of carbon, hydrogen and bromine standards. intermediates in organic synthesis. Determination of strontium. Organic microanalysis for the determination of carbon, hydrogen and bromine standards. used as analytical reagent, also used in organic synthesis |
| production method | p-bromotoluene is obtained by oxidation and acidification. After P-bromotoluene, water and potassium hydroxide were mixed, the mixture was heated and boiled, potassium permanganate was added in portions, and then refluxed for 4H, and then filtered and acidified to obtain crude product. In dilute ethanol with ammonia dissolution, filtration, hydrochloric acid neutralization, washing to get the finished product. |
