1-Bromo Propane is colorless or light yellow transparent liquid, neutral or slightly acidic, light sensitive, m.p.-110℃,b.p.71℃, relative density 1.357 (20 ℃), n20d 1.4341, can be any proportion with alcohol, ether mixed, slightly soluble in water. 1-Bromo Propane, as an organic synthetic material, is used in the synthesis of organophosphorus insecticidal insecticide, parathion, C-P, C-bromo phosphate, etc., also can be used in medicine, dyestuff, spice industry, as well as the material of the GE reagent, CAS number is 106-94-5. The preparation methods of 1-bromo propane are mainly in the following two kinds. by N-propyl alcohol and hydrobromide reaction. Adding hydrogen bromate into concentrated sulfuric acid and adding N-propyl alcohol to heat reflux 0.5h. In 70-75 ℃, all the generated bromine propane is steamed out, then the concentrated hydrochloric acid is washed, then the sodium carbonate and the ph is 7. Use anhydrous sodium sulfate to dry, filtration, filtrate distillation, collect 69-74 ℃ fractions, obtain bromine propane. The reaction between n-propyl alcohol and sodium bromide. The N-propanol and water and sodium bromide are heated to the reflux, and the 69-72 ℃ drops and sulfuric acid are added, and then the reflux 2h is continued. Distillation, collect 68-100 ℃ distillate, wash with sodium carbonate solution to neuter, then distill, collect 68-76 ℃ distillate namely bromine propane. In addition, in the presence of red phosphorus, propyl alcohol and bromine can also be prepared for the preparation of bromine propane.
