| Introduction | bromododecane is a halogenated hydrocarbon with the chemical formula C12H25Br, which can be used for the synthesis of neoglucene chloride and other chemicals. |
| uses | is mainly used in organic synthesis, in medicine for the synthesis of disinfection drugs such as neoglucinamide, Mesilate, etc. Used as solvent, it can also be used for the synthesis of flame retardant antimony Tris (dodecylmercaptan), antioxidant dodecylmercaptan, surfactant dodecyldimethyl benzyl ammonium chloride (benzalkonium bromide), benzalkonium bromide, and other flame retardants and surfactants. used as solvent, also used in organic synthesis |
| production method | 1. Hydrobromic acid method is derived from the interaction of lauryl alcohol (N-decanediol) and hydrobromic acid. Lauryl alcohol was added to the enamel glass reaction Pan, stirred and cooled, and sulfuric acid was slowly added. After stirring for 1H, additional hydrobromic acid was added. The temperature was gradually increased to 90-95 °c and the reaction was stirred for 8H. After completion of the reaction, the temperature was lowered to 30 °c and allowed to stand for 8H. The acid layer was separated, and the oil layer was adjusted to pH 8 with dilute alkali solution. The alkali solution was separated and washed with 50% ethanol. By distillation under reduced pressure, a fraction of 140-200 ° C. (3.33kPa) was collected to obtain purified 1-bromododecane. 2. Sodium bromide method 3. Bromination method |
