1-Bromobutane Chemical Properties,Uses,Production

Chemical Properties

clear colorless to slightly yellow liquid


1-Bromobutane is used in the synthesis of procaine and tetracaine.

General Description

A clear colorless liquid. Flash point 65°F. Denser than water and insoluble in water. Vapors heavier than air.

Air & Water Reactions

Highly flammable. Insoluble in water.

Reactivity Profile

1-Bromobutane is incompatible with strong bases and oxidizers [USCG, 1999].

Health Hazard

Irritating 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.

Purification Methods

Wash 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.]
