1-Bromobutane Usage And Synthesis
  • Chemical Propertiesclear colorless to slightly yellow liquid
  • Uses1-Bromobutane is used in the synthesis of procaine and tetracaine.
  • General DescriptionA clear colorless liquid. Flash point 65°F. Denser than water and insoluble in water. Vapors heavier than air.
  • Air & Water ReactionsHighly flammable. Insoluble in water.
  • Reactivity Profile1-Bromobutane is incompatible with strong bases and oxidizers [USCG, 1999].
  • HazardFlammable, dangerous fire risk.
  • Health HazardIrritating to the eyes, nose, throat, and upper respiratory tract. Symptoms of exposure include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting. Irritating to the skin.
  • Safety ProfileModerately toxic by intraperitoneal route. Mddly toxic by inhalation. Dangerous fire hazard when exposed to heat, flame, or oxidizers. Violent reaction with bromobenzene + sodium above 30℃. Can react with oxidizing materials. To fight fire, use CO2, dry chemical, mist or spray. See also BROMIDES.
  • Potential ExposureButyl bromide is a highly flammable, colorless liquid with a pleasant odor. Molecular weight 5 137.04. Specific gravity (H2O:1) 5 1.28 @ 20C; boiling point 5 101.3C; freezing/melting point 5 2112.4; vapor pressure 5 42 mmHg @ 25C; vapor density (air 5 1) 5 4.68; flash point 5 17.2C (n-); 21C (sec-isomer). Autoignition temperature 5 269C. Explosive limits: LEL: 2.5% @ 100C; UEL: 6.6% @ 100C. Hazard identification (based on NFPA-704 M Rating System): Health 1; flammability 3; reactivity 0 ?. Insoluble in water
  • ShippingUN1126 & UN23391- & 2-Bromobutane, Hazard Class: 3; Labels: 3—Flammable liquid.
  • Purification MethodsWash the bromide with conc H2SO4, water, 10% Na2CO3 and again with H2O. Dry it over CaCl2, CaSO4 or K2CO3, and distil it. Redistil it after drying with P2O5, or pass it through two columns containing 5:1 silica gel/Celite mixture and store it with freshly activated alumina. [Beilstein 1 IV 258.]
  • IncompatibilitiesVapor may form explosive mixture with air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. May accumulate static electrical charges and cause ignition of its vapors.
  • Waste DisposalDissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed
