1-Bromopropane
1-Bromopropane (n-propylbromide or nPB) is an organobromine compound with the chemical formula CH3CH2CH2Br. It is a colorless liquid that is used as a solvent. It has a characteristic hydrocarbon odor. Its industrial applications increased dramatically in the 21st century.
Preparation
Industrial routes to 1-bromopropane involve free-radical additions to the corresponding alkenes. In this way, the anti-Markovnikov product is obtained.
A laboratory synthesis involves treating propanol with a mixture of hydrobromic and sulfuric acids:
Alternate synthetic routes include treating propanol with phosphorus tribromide. or via a Hunsdiecker reaction with butyric acid.
Applications
Like many other liquid halocarbons, 1-bromopropane finds use as a liquid or gaseous solvent. It is a solvent for adhesives in aerosol glues that glue foam cushions together. It is a solvent in asphalt production, in the aviation industry for maintenance, and in synthetic fiber production.It is a solvent for degreasing plastics, optics and on metal surfaces, to remove soldering residues from electronic circuit boards.
