1,3,5-TRIBROMOBENZENE

Bromobenzenes are organic halogen compounds of cyclic aromatics formed by replacing hydrogen atoms in benzene by 1-6 atoms of bromine. There are 12 compounds of chlorobenzenes of mono-, three isomeric substances each of di-, tri-, and tetra-, as well as penta- and hexachlorobenzene.

Lower bromobenzenes are clear liquid at room temperature while higher bromobenzenes are white to yellowish solids. They are practically insoluble in water and denser than water. . The water solubility is decreasing if more brominated. The flammability of bromobenzenes are very low, the octanol/water partition coefficients are moderate to high, increasing with more brominated, and vapour pressures are low to moderate, decreasing with more bromobenzenes. The taste and odour thresholds are low, decreasing with lower bromobenzenes. The commercial bromobenzenes are used as heavy liquid solvents, motor oil additives. and as an intermediates to manufacture organic chemicals including pharmaceuticals, pesticides and flame retardants for polymeric materials.
