| 2-Bromobutane Usage And Synthesis |
| Chemical Properties | colourless liquid with a pleasant odour |
| Uses | 2-Bromobutane is used in the various organic synthesis, existing as a grignard reagent. |
| Uses | 2-Bromobutane is utilized in the synthesis of non-nucleosides. It is used as a solvent as well as an intermediate in organic synthesis. It is an important raw material used to prepare Grignard reagent by reacting with magnesium. Further, it reacts with hydrocyanic acid to prepare sodium salt to get (+-)-sec-butyl cyanide. It is an important raw material used to prepare Grignard reagent by reacting with magnesium. |
| General Description | A colorless to pale-yellow colored liquid with a pleasant odor. Flash point 65°F. Insoluble in water and denser than water. Vapors are heavier than air and may be narcotic in high concentrations. Used to make other chemicals. |
| Air & Water Reactions | Highly flammable. Insoluble in water. |
| Reactivity Profile | Halogenated aliphatic compounds, such as 2-Bromobutane , are moderately or very reactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. Low molecular weight haloalkanes are highly flammable and can react with some metals to form dangerous products. Materials in this group are incompatible with strong oxidizing and reducing agents. Also, they are incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides. Gives toxic fumes of bromine when burned. |
| Hazard | Narcotic in high concentration. Flammable, dangerous fire risk. |
| Health Hazard | Irritating to eyes, nose, throat, upper respiratory tract, and skin. Symptoms of exposure include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting. |
| Safety Profile | Narcotic in high concentrations. Questionable carcinogen with experimental neoplastigenic data. See also BROMIDES and CHLORINATED HYDROCARBONS, ALIPHATIC. Flammable liquid. Dangerous fire hazard when exposed to heat or flame. When heated to decomposition it emits toxic fumes of Br-; can react with oxidzing materials. To fight fire, use water, spray or mist, foam, Co2, dry chemical. |
| Purification Methods | Wash 2-bromobutane with conc HCl, water, 10% aqueous NaHSO3, and then water. Dry it with CaCl2, Na2SO4 or anhydrous K2CO3, and fractionally distil it through a 1m glass helices packed column. [Beilstein 1 IV 261.] |
